Free online PDF editor

pdfredX is a free PDF editor that runs entirely in your browser. Merge, split and compress PDFs, add annotations and watermarks, recognize text with OCR, redact confidential data and convert photos to PDF — with no software to install and no sign-up.

What makes it different is privacy: your files are never uploaded to a server. All processing happens on your own device, so documents never leave your computer or phone. The tools work on Windows, macOS, Linux, Android and iOS.

Frequently asked questions

Is pdfredX free to use?
Yes. Every pdfredX tool is free with no limits. No account and no payment required.
Are my files uploaded to a server?
No. pdfredX processes PDFs and images directly in your browser on your device. Files are never sent anywhere and stay fully private.
Do I need to install anything or sign up?
No. pdfredX works in the browser with no installation and no account. You can optionally add it to your home screen as an app using the «Install» button in the header.
Which formats are supported?

Does pdfredX work on mobile?
