Why TrustPDF

Runs on your device

Processing happens in your browser with open-source libraries. Close the tab and nothing remains.

Nothing to sign up for

No account, no email, no cookies. Not even a cookie banner, because there is nothing to accept.

Fast and free

No queues, no limits, no watermarks. Files are ready the moment the work is done.

Verifiable

The code is public under the AGPL v3. Read it, run it yourself, or check it on GitHub.

How it works

  1. Open a tool. The page loads open-source PDF libraries into your browser.
  2. Add your file. It is read straight from your disk into the page's memory, never sent over the internet.
  3. Save the result. Your browser builds the new file and saves it to your device. Close the tab and nothing is left behind.

Frequently asked questions

Is TrustPDF really free?

Yes. Every tool is free, with no sign-up, no watermarks, no daily limits and no premium tier. The project is open source and supported by donations and a few clearly marked affiliate links.

Are my files uploaded to a server?

No. All processing happens in your browser with open-source JavaScript libraries (pdf-lib and PDF.js). Your files never leave your device, and the site's Content-Security-Policy stops pages from sending anything to any other site.

Does TrustPDF work offline?

Yes. After your first visit the browser keeps a copy of the site's pages and scripts, so the tools open and work with no internet connection at all; switch off your Wi-Fi and try it. OCR, password tools and non-Latin watermark fonts need one online use first, because their larger files are stored when first used. You can also install TrustPDF as an app from your browser's menu.

Does it work on phones and tablets?

Yes. TrustPDF works in any modern browser on Windows, macOS, Linux, Android and iOS. Very large files can be slow on older phones.

Can I use TrustPDF for confidential documents?

That is what it is built for. Since files are never uploaded, nobody else can see or keep them. You can verify this in the source code on GitHub, or watch your browser's network tab while you use a tool.

What can't TrustPDF do yet?

It cannot crack a password you don't know, fill PDF forms, or convert PDFs to Excel. OCR, PDF to Word, signing, cropping and password protection are all here and run in your browser.
