More free PDF tools
Same quality bar. Still free. Still no upload.
Your files never leave your device
Free to use, with no account, no usage limit and no watermark, because the work runs on your device rather than on our servers.
This is not a promise about how carefully we handle your upload. There is no upload. The file you choose is read into memory by your own browser, processed there, and handed back as a download — the tool has no server component and makes no network request with your data.
- Nothing is stored. We never receive the file, so there is no copy to retain, no retention period to disclose, and nothing to delete on request.
- Nothing is transmitted. No upload endpoint, no analytics payload carrying file contents, no third-party processor.
- You can verify it. Load this page, disconnect from the internet, and use the tool. It still works, because everything it needs is already on your machine.
- Nothing persists after you close the tab. Files are held in page memory only — not in local storage, not in a cache, not in a database.
A note on wording, because it matters: we do not describe these tools as “encrypted.” Encryption protects data that travels to somebody else's computer. Your file does not travel, so there is nothing to encrypt and nothing to intercept — which is a stronger guarantee than encryption, not a weaker one. The page itself is served over HTTPS like the rest of the site.
This makes the tools safe for material you are contractually barred from uploading to third-party services — client footage under NDA, unreleased campaign assets, anything covered by a confidentiality clause.
How it works
1. Drop a PDF
Up to 150 MB and 500 pages, opened in your browser.
2. Set the format
Pick one of six positions, a start number, margin, size and a template like {page} / {pages}.
3. Download the numbered PDF
Numbers are added as real text in Helvetica, so the rest of the page is untouched.
Questions
Why is the number on the wrong edge of a landscape page?
PDF rotation is a flag on the page, not a rewrite of its coordinate system. Numbers are placed in that native space. bottom-centre is the bottom of the unrotated media box. A page stored as portrait and flagged 90° will show the number on a visual side. Rotate the page first if the edge has to match the screen.
Can I use my brand font?
No. The stamp is Helvetica, one of the 14 fonts every PDF viewer already has, so nothing extra is embedded. Characters outside WinAnsi (most emoji, many CJK glyphs) are replaced with a question mark rather than aborting the file.
Can I start numbering at a number other than 1?
Yes. Set Start at, and every number shifts by that much, including {pages}, so a file starting at 5 with 10 pages reads 5 / 14 on its first page. Use {page} alone if you only want the page number.

These rearrange files. Versely makes new ones.
Everything on this page works on a file you already have, which is why it costs nothing. Generating something that did not exist (video from a prompt, a voice, a score) runs a model, and that costs credits.
