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 redact PDF

Redact PDF lets you draw boxes over sensitive content and, when rasterized, permanently removes the text and images underneath. Use it before sharing documents that contain private information.

  1. Add your PDF; pages render on your device and are never uploaded.
  2. Click and drag on a page to draw a black redaction box, and click a box to remove it.
  3. Keep 'Rasterize redacted pages' checked so the hidden content is truly deleted.
  4. Click Apply redaction, then preview and download the redacted PDF.

Good to know: Covers areas and re-renders pages so hidden text is removed.

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.

Is the hidden text really gone, or just covered?

With rasterize enabled (the default), redacted pages are re-rendered as images, so the covered text no longer exists in the file. Unchecking it only draws boxes on top, and the text underneath could still be extracted.

Which pages get rasterized?

Only the pages you drew boxes on are re-rendered; untouched pages are copied through unchanged.
