How your files are handled

We built these tools so you never have to wonder where your documents go. Here is exactly what happens when you use them.

  • Your files are processed entirely in your browser using open-source libraries (pdf-lib, PDF.js, and others).
  • Nothing is uploaded to our servers. We have no backend that receives, stores, or scans your documents.
  • We cannot see, store, or access your files — not during processing, not after, not ever.
  • Processing uses your device's memory and CPU. Large files may take longer, especially on phones and tablets.
  • All tools are free with no paywall tricks, no hourly task limits, and no watermarks on your output files.

How it works

Three simple steps. Your files never leave your device, and the result downloads straight to your computer or phone.

How to add Page Numbers

Add Page Numbers stamps numbers onto your PDF in the position and format you choose, with a live preview of page one. It works well for reports, contracts, and printed handouts.

  1. Add your PDF; it loads locally and is processed only on your device.
  2. Pick the position, number format, starting number, font size, and which pages to number.
  3. Check the live preview on page one to confirm placement.
  4. Click Add page numbers, then preview and download the numbered PDF.

Everything happens in your browser — your file is never uploaded, and there is no sign-up, watermark, or limit.

Frequently asked questions

Are my files uploaded to a server?

No. Every tool runs entirely in your browser using open-source libraries, so your file is processed on your own device and is never uploaded. We have no backend that receives, stores, or scans your documents.

Is it really free, and will there be a watermark?

Yes. There is no account, no sign-up, and no hourly limit, and the tools never add a watermark to your output. UnboundPDF is free and is not affiliated with Adobe.

Does it work on a phone or tablet?

Yes. The tools run in any modern mobile browser as well as on desktop. Because the work uses your device's own memory and processor, very large files simply take longer on phones.

Can I start numbering from a page other than the first?

Yes. Set the page range to number and the first number independently, so you can skip a cover page or begin counting at any value.

What number formats are available?

You can use plain numbers, 'Page 1', '1 of N', or 'Page 1 of N', and choose small, normal, or large text.
