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 split PDF

Split PDF lets you pull a specific range of pages out of a document, or break a PDF into one file per page. Use it to save just the pages you need or to separate a bundle into individual pages.

  1. Add one PDF by dropping it in or browsing; it is read locally on your device, with nothing sent anywhere.
  2. Choose Extract pages and click thumbnails (or type a range like 1-3, 5), or choose Every page to get one PDF per page.
  3. Check the selection summary, then click Split PDF.
  4. Preview the output and download a single PDF of your chosen pages, or a ZIP when splitting every page.

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.

How do I type which pages to keep?

Enter page numbers and ranges separated by commas, such as 1-3, 5, 8-10. Clicking thumbnails fills in the same box automatically.

What do I get when I split every page?

You get a ZIP file containing one single-page PDF for each page of the original document.
