What Swift-Slide does well,
and where it struggles.

Conversion & quality

How long does conversion take?

In measured examples as of July 2026, a single page finishes in about 30 seconds, 15 pages in about 1 minute, and even a large 111-page deck in about 4 minutes. Multiple pages are processed in parallel, so the time doesn't scale linearly with page count. Everything runs on the server, so conversion continues even if you close the screen, and you can check the status anytime from the dashboard (times vary with load and source material and are not guaranteed).

How many pages can I convert?

There is practically no page limit (up to 1,000 pages per upload). File size is up to 50MB for a PDF, and you can convert as many pages as your credit balance allows (1 page = 1 credit). If your balance is short, you can also choose a partial conversion that processes only as many pages from the start as your balance covers.

Can I upload a PowerPoint (.pptx) file directly?

Supported formats are PDF and images (PNG, JPEG, WebP). PowerPoint and Word can't be uploaded directly. Export a PDF from PowerPoint ("Export" / "Save as PDF") and upload that PDF instead (up to 50MB for PDF, 10MB for images).

I heard NotebookLM was renamed to Gemini Notebook. Can I convert Gemini Notebook slides?

Yes. Gemini Notebook is the new name for NotebookLM (renamed in July 2026) — it's the same product. Slides and infographics generated with Gemini Notebook convert exactly as before.

Does it work with PDFs and images from tools other than NotebookLM?

Yes. Beyond NotebookLM (now Gemini Notebook), it converts slides and infographics made with Canva, Gamma, and other AI tools, as well as scanned images — any material that ends up as a PDF or PNG/JPG. See the sections above for what converts best.

Can I use the converted files commercially?

Yes. You retain the rights to the materials you upload (Terms of Service, Article 5), and the converted PPTX is yours to use — there are no restrictions from us on business or commercial use.

Can I convert slides in languages other than Japanese (e.g. English)?

Yes. Text recognition supports multiple languages, so slides in English and other languages can be made editable. Note that the font is standardized to Meiryo, so Latin text may look somewhat different from the original.

Will it look exactly like my original slide?

Not an exact match. Swift-Slide prioritizes handing you an editable result over reproducing the exact look. Text size and placement are estimated from the original image and reproduced, but the font is standardized to Meiryo and colors may differ slightly. You can fine-tune the finish in the editor or in PowerPoint.

What if some text was recognized incorrectly?

Double-click the text in the editor to rewrite it on the spot. Drag to move it, and use the left/right handles to adjust the width (wrapping). Text size is changed from the number in the properties panel (dragging the frame doesn't change it).

Where do I edit the other pages of a multi-page document?

Switch pages with the "Page 1", "Page 2"… tabs at the top of the editor. Edits are saved automatically per page. Pages that failed to convert appear as red tabs, and you can re-run them from there.

What happens to tables, charts, and photos?

Figures, charts, and photos are kept as images (as "part of the artwork"), and readable text on top of them is made editable. A table's cell structure itself does not become an editable table — it stays as an image (to preserve the layout, the whole figure is treated as a single image).

Text on top of a logo or illustration didn't get removed

That's by design. Text overlapping logos, icons, and illustrations is treated as "part of the design," and we deliberately don't remove it or turn it into text so as not to break the artwork. If you do want to remove that text, brush over the spot with the editor's "eraser (background repair)" and the AI will cleanly repair it along with the background (no credits needed).

A figure, logo, or illustration disappeared

Conversely, a figure or logo can be mistaken for standalone text and get removed. Use the editor's "insert from original" to crop the part from the pre-conversion image and restore it as-is (no credits needed). See the "Insert from original" section on this page for details.

Decorative text (comic sound effects, 3D styling) turned into plain text

Flashy decorative text — burst/comic sound effects, onomatopoeia, 3D or multi-outline styling — can't be reproduced by PowerPoint's standard features, so we try to keep it as an image. Depending on the slide, though, it may get converted into plain editable text. To keep the original design, use the editor's "insert from original" to crop that part and paste it back as an image (no credits needed).

Which software can open the exported PPTX?

It's exported in the standard PowerPoint format (.pptx), so besides Microsoft PowerPoint (Windows / Mac / web), you can also import and edit it in Google Slides or Keynote.

Can it export as PDF?

Export is PPTX only. If you need a PDF, open the exported PPTX in PowerPoint or Google Slides and use "Export as PDF" there.

What happens to a PDF that mixes portrait and landscape pages?

PowerPoint allows only one slide size per PPTX file. The slide size is therefore based on the orientation used by the majority of pages (landscape if tied), and pages with the other orientation are scaled down — keeping their aspect ratio — and centered on the slide with margins on the sides. Nothing gets cropped or distorted.

Data safety

What happens to the PDF I upload?

The original file you upload is automatically deleted once the conversion finishes. The editor images and edit data are kept only for your plan's retention period (Free: 24 hours / Starter: up to 7 days / Pro & Business: up to 30 days), and are permanently deleted once that period passes.

Could my slide content be used to train AI?

No. Each AI service we use for text recognition and image repair is contracted and configured not to use input data for training (via zero data retention and similar). See the list of subprocessors in our Privacy Policy for details.

Is it safe to upload confidential materials?

All communication is encrypted, stored data is kept in private storage, and the original file is deleted right after processing. If you want to be extra careful, you can shorten the retention period to as little as 1 day on the settings page, or manually delete the project after converting.

Where (which countries) is my data stored and processed?

Your data is stored and processed on the cloud services we use. The main locations are Japan and the United States (the application platform runs on Google Cloud's Tokyo region; background restoration and text recognition use data centers in Japan or the US; authentication, database, and storage are mainly in the US). The location of each subprocessor and how cross-border transfers are handled are described in the "External services (subprocessors)" and "Cross-border transfer" sections of our Privacy Policy. Uploaded original files are deleted right after processing, and edit data is permanently deleted after the retention period.

Can I get a copy of the personal data you hold about me?

Yes — you can download it yourself as a JSON file from "Download your retained personal data" on the settings page. Request a confirmation code, enter the 6-digit code sent to your registered email address, and the download starts. It includes your account information, conversion history, credit records, support history, and payment records (date, amount, plan name, status, and receipt). It does not include the uploaded documents themselves, data whose retention period has passed and which we no longer hold, or our own accounting details such as processing fees. If you have a large number of entries, some sections are capped and both the screen and the file say so — request the complete set from our inquiry desk. Correction and suspension-of-use requests are handled at the same desk.

Does an AI read my support inquiries?

Yes. To reply faster, we send the content of your inquiry to Google's AI service (Vertex AI / Gemini) to generate a reply automatically. We use it configured so that your input is not used to train the AI model. Anything the AI cannot answer reliably is handled by a member of our staff. Statutory requests — such as disclosure, correction, or suspension of use of your personal data — and anything involving legal matters are never answered automatically by the AI; a member of our staff always handles them. Individual inquiries cannot be excluded from this AI processing, so please keep that in mind if your inquiry needs to include confidential details.

How do I delete my account and data?

You can delete your account from the settings page. All projects, edit data, and account information are erased and can't be recovered. On a paid (individual) plan, the subscription is cancelled immediately when you delete (there are no prorated refunds; since deleting mid-period wastes the remaining days, we recommend deleting after your renewal date). If you are a team owner, deleting your account dissolves the team: all members return to Free and the team's contract (including seats and boosts) is cancelled immediately — the team does not remain even if members are still in it (to keep the team, transfer ownership before deleting). If you are a team member (not the owner), only you leave and the team and the owner's contract continue.

Using it & troubleshooting

What happens to my credits if a conversion fails?

Credits are only used for pages that convert successfully. If the whole thing fails, nothing is used. Please re-upload the same file from the dashboard. If it keeps failing, contact us.

Only some pages failed to convert

When the completion screen shows "Converted N/M pages (some failed)," the failed pages aren't included in the PPTX or the editor, and no credits were used for them. Failed pages are automatically retried once after about 30 minutes. If you want to fix them right away, you can re-run processing from the failed pages (red tabs) in the editor or from the processing status screen (no need to re-upload the file).

The conversion progress isn't moving / it's taking a long time

This is usually temporary load or the processing server warming up after a period of inactivity. Everything runs on the server, so it's fine to close the screen. As soon as the dashboard shows "Completed," you can edit and download. Pages that didn't succeed are retried automatically. If the progress (%) hasn't changed for more than 30 minutes, please contact us.

Can I convert a password-protected (encrypted) PDF?

No. Password-protected PDFs show an error at upload. Remove the PDF's password protection and upload it again.

Can I use it on a smartphone?

Yes. Uploading, converting, and downloading the PPTX all work the same on a smartphone. Editing works too, but for finer adjustments we recommend landscape orientation or a PC.

How do I operate the editor on a smartphone?

Use two fingers to move (pan) the slide and pinch to zoom in and out. You can select, move, and edit elements with taps and drags. Swipe left or right to switch pages (except while zoomed in or with an element selected). For finer adjustments we recommend a PC or landscape orientation.

I want to compare before and after the conversion

Use the "Compare" button at the top of the editor to overlay the pre-conversion original image and the converted slide (background) with a slider (your text edits aren't included in the comparison).

Can I change the color of just part of the text, or add highlighter?

Text color can be changed for just a selected range while editing the text. The highlighter (marker) is applied per text box (it can't be applied to only part of the text).

Can I use the eraser (background repair) as many times as I want?

It doesn't use credits, but there's a limit on how many times it can be run per page (Free 1 / Starter 2 / Pro 3 / Business 5; this count is shared with Separate objects). Each run is recorded as a version, and you can always go back to a previous state from the thumbnails at the bottom of the eraser screen (going back does not restore the used count). For pages that hit the limit, adjust in PowerPoint after exporting the PPTX, or re-convert the project.

What happens to inserted images when I revert the eraser to a previous version?

Inserted images (such as those pasted back with "insert from original") remain as they are. Only the background reverts, so if the content looks duplicated, select and delete the images you no longer need.

Is it safe to edit in multiple tabs or on multiple devices at the same time?

Simultaneous editing is not supported. If the same project is open and edited in multiple tabs or devices at once, whichever saves last overwrites the rest and earlier edits can be lost. Please edit in a single tab (device).

Is there a list of keyboard shortcuts?

Ctrl+Z (undo) / Ctrl+Y (redo) / Ctrl+D (duplicate) / Ctrl+A (select all text) / Ctrl+S (save now) / Delete (delete) / arrow keys (move 1px; 10px with Shift) / Escape (deselect). On Mac you can use Cmd instead of Ctrl. Shift+click for multi-select, and right-click opens a menu with duplicate, bring to front / send to back, and delete.

Can I make text or images semi-transparent?

Yes. Select the element and adjust the "Opacity" slider in the properties panel. The opacity you set is reflected in the exported PPTX as well.

How do I remove the watermark?

PPTX files exported on the Free plan include a watermark. After upgrading to Starter or higher, re-download the PPTX from the same project to get it without the watermark (within the retention period, no re-conversion is needed and no credits are used).

Can I get a receipt?

From "Payment history" under "Plan & billing," open the "Details" for each payment to view and save the receipt (issued by Stripe). Note: on an enterprise invoice contract (bank transfer), payments do not appear in the on-screen history — we send invoices and receipts to you directly.

How do I use it with a team?

The Business plan includes 3 seats, so you can invite team members and share the monthly credits (additional seats are ¥2,200/seat per month with +150 monthly credits per seat). Projects themselves are kept separate per member and aren't visible to other members.

I can't sign in — what should I check?

Swift-Slide uses Google or Microsoft sign-in (there is no password). First, make sure you're signing in with the same account you used when you registered. If the problem persists, contact us via the no-sign-in contact form linked in the page footer, or by email (info@swift-slide.com).

I signed in with a different Google/Microsoft account and my projects disappeared

An account is created per email address, so signing in with a different account creates a new, empty account and your previous projects won't appear. Sign back in with the account (email address) you used before to see your data. Note that moving or merging data between accounts is not possible.

If I sign in with Google or Microsoft, is it the same account?

In principle, yes — if the email address is the same, the two sign-in methods are automatically linked to the same account, and either one gives you the same projects and credits. However, with some organizational Microsoft accounts the email address can't be verified; for safety the accounts are not linked in that case and the second sign-in method may fail with an error. If that happens, use the sign-in method you originally used.

Something seems broken — where can I check service status?

swift-slide.com/status shows the current status and the last 30 days of incident history for each feature group (conversion, editor & storage, payments). If something seems off, please check there first.

What can I do in the demo editor on the top page?

It's a lightweight version you can try without signing up: text editing and PPTX export. AI features such as the eraser (background repair) and insert-from-original are not available in the demo, edits are not saved, and demo PPTX exports include a watermark. To convert your own file, try the Free plan (free to sign up, no credit card required).

I'm not receiving emails from Swift-Slide

Check your spam folder and make sure you can receive emails from info@swift-slide.com. If you're using a company email address, the message may also be quarantined by your organization's filter. If instead you want fewer emails, you can turn off "Conversion complete", "New features and campaigns", and "Expiry reminders" individually under "Email notifications" on the settings page (the unsubscribe link in each email works too). Messages tied to your contract and transactions — payments, replies to your inquiries, team invitations, and changes to the Terms — cannot be turned off.

Do you issue qualified invoices (Japan invoice system)?

We are currently considering registration as a qualified invoice issuer. Invoices and receipts issued at this time do not include a registration number. Once registered, subsequent invoices will include it.

Where can I send feedback about conversion quality?

From the dialog shown right after downloading your PPTX. Choose "Satisfied" to optionally rate your satisfaction (1-5 stars) and pick what you liked, or "Something could be better" to select issue categories and leave a comment. Your feedback is used to improve quality.

I agreed to have my comment published as a user testimonial, but want to withdraw it

Contact us via "Support" in the app and we will unpublish it promptly. Only comments with explicit consent are published, each is reviewed by a person before publishing, shown anonymously (the display name you entered or your plan name), and automatically unpublished if you delete your account.

What is "Separate objects"?

AI detects illustrations, icons, and figures on the slide and lifts them off the background so you can move them individually (available on Starter plans and above). Open "Separate objects" at the top of the editor, tap the candidate boxes (or drag to add your own selection), review the cutouts, then apply. Applying uses one of the per-page uses shared with the eraser (background repair) — one use no matter how many objects you select, and no credits are consumed. Separated objects are also exported to the PPTX as transparent images.

Object separation cuts out poorly / the button doesn't appear

Complex illustrations with many overlapping elements and ring shapes like donut charts are hard to cut out. Choosing "Keep background" on the review screen inserts the object as a rectangle instead, which is usually enough for layout adjustments. To rotate a separated object, use the editor's rotation handle after separating. This feature also requires a supported browser (the latest Chrome / Edge, etc.); on unsupported browsers the button appears locked and explains that it isn't available.

How does the selection screen work? (select all, limits, etc.)

Tap the detected boxes to select or deselect them, or use "Select all" / "Deselect" to toggle them at once. Drag on empty space to add a manual region; a selected box can be moved, resized, or deleted. Up to 30 objects can be separated at a time. The first run downloads the cutout AI model (about 84MB), which may take a while — it's cached in your browser, so later runs skip the download.

Credits & retention

How much can I try for free?

On first sign-up you receive a bonus of 20 credits (valid for 30 days from grant), so together with the 3 monthly credits you can convert up to 23 pages in your first 30 days — enough to convert a full real document. Exports on the Free plan include a watermark (bonus credits included). The first-time bonus is granted once per account.

When are credits replenished?

The Free plan resets to 3 credits on the 1st of each month. Paid plans reset to the plan's monthly credits on your billing renewal date. Unused credits don't carry over to the next month.

What is the first-month boost (bonus credits)?

When you subscribe to a paid plan for the first time, bonus credits are granted separately from your monthly credits (Starter +30 / Pro +100 / Business +300; valid for 30 days from grant; Business bonuses are shared by the whole team). When upgrading, only the difference from the highest plan you've ever reached is granted (e.g. +70 when moving from Starter to Pro). No re-grant occurs when re-subscribing to or re-reaching a plan you've held before.

What's the expiration and usage order for credit packs and bonuses?

Packs are valid for 90 days from purchase; bonuses (first sign-up / first-month boost) are valid for 30 days from grant. Credits are used automatically in the order "monthly credits → bonuses and packs (closest expiration first)," so the shortest-lived credits are never wasted. Purchased packs and granted bonuses stay usable until their expiration even if you later change or cancel your plan.

What happens to my remaining credits when I upgrade?

Your remaining credits carry over. In addition, the difference in monthly credits between plans is added in proportion to the time left in your billing period (pro-rated), and if you're reaching the plan for the first time, the first-month boost (bonus, valid 30 days from grant) is granted separately. When switching from Free to a paid plan, the full monthly credits of the paid plan are added. Upgrading to Business creates a new contract under the team's name; your individual plan ends immediately and your remaining credits carry over into the team's credits.

What is "priority processing"?

It processes Pro/Business plan conversions in a priority lane during busy periods. When it's not busy, all plans are processed at the same speed.

What payment methods are available?

All plans are paid by credit card (Visa, Mastercard, American Express, etc.; Stripe Link is also supported). Bank transfer and convenience-store payment are not supported. Invoices and receipts (PDF) are issued on all paid plans, but payment itself is by card. The name (company name) can be set on the "Plan & billing" page. Exception: enterprise invoice contracts (bank transfer, annual upfront) are billed by our team directly.

How will it appear on my card statement?

It appears as "SWIFTSLIDE.COM".

Who are the Business plan's contract and billing tied to? (corporate use)

The Business plan is a contract under the team's name, and billing (card, invoices, receipts) is tied to the team and managed by the owner. Members can't buy credit packs or change billing settings (ask the owner if needed). The name (company name) on receipts and invoices can be set on the "Plan & billing" page.

What if we need more than 50 seats, or purchase-order / bank-transfer procurement? (Enterprise)

If you need to go beyond the Business plan's limits (50 seats, +9,000 monthly boost credits), or need purchase-order / bank-transfer procurement or security questionnaire support, we handle these individually. Enterprise contracts are offered only as annual contracts (1 year or longer) paid upfront by bank transfer — we do not offer monthly or short-term individual contracts. Use "Enterprise & large-scale deployment" on the pricing page or the "Deployment inquiry" category in the contact form, and tell us your expected scale (people, pages per month) and requirements. A member of our team will review and respond.

How do I invite members?

Invite them from the team page by entering their email address. They can join via the link in the invitation email. Invitations expire after 7 days, so send a new one if it has expired.

What happens to billing when I change the team owner?

Even if you change the owner, the contract and billing stay with the team and carry over, and service isn't interrupted. The email that invoices are sent to switches to the new owner. If the payment card needs to change, the new owner can update it anytime from the "Plan & billing" page.

Where can I find receipts and invoices? Can I set the name (company name)?

From "Payment history" on the "Plan & billing" page, use the "Details" link for each payment to view invoices and receipts (downloadable as PDF). Plans, additional seats, and boosts are issued as invoices, while add-on credit packs are issued as receipts. The name (such as a company name) can be set under "Name on receipts and invoices" on the same page and applies to documents issued afterward (it isn't applied retroactively to already-issued documents). For team use the owner sets it; on an individual plan you set it yourself. Note: for enterprise invoice contracts (bank transfer), invoices and receipts are sent by our team instead.

What happens to my credits if I downgrade or cancel?

You can keep using your current plan and credits until the current billing period ends. On your next renewal date you switch to the new plan, and your credits reset to that plan's monthly amount. If you cancel, you return to the Free plan (3 credits/month) after the renewal date. There are no prorated refunds.

Can I pause my subscription?

Yes. Instead of cancelling a paid (individual) plan, you can choose to "pause" — skipping payment for just one upcoming renewal (it's offered as a retention option when you go to cancel). While paused, that renewal's charge and monthly credit grant are skipped, and your next grant/renewal date shifts back by one cycle. You can still convert using the credits you already have while paused (plan perks stay too). It resumes automatically after one cycle, and you can also resume immediately from "Plan & billing." Note: team members (other than the owner) can't use this.

Can I re-register after deleting my account?

You can re-register anytime with the same account. However, the first sign-up bonus (+20 credits) is checked against deletion records to prevent abuse and is generally not granted again on re-registration. Data deleted when you closed your account can't be recovered.

How long is my converted data kept?

The retention period for edit data varies by plan (Free: 24 hours / Starter: up to 7 days / Pro & Business: up to 30 days). Within that period you can re-edit in the editor and re-download the PPTX as many times as you like. Once the period passes, the data is permanently deleted and can't be recovered (you'd need to upload again). You can shorten it further under "Retention days" on the settings page. Note that this retention period is about your slide edit data. Records of your purchases (date, amount, plan name, and so on) are kept as accounting books required by law, for 10 years from the end of the fiscal year in which the transaction falls (see our Privacy Policy).
