No upload. No server. 100% in your browser.

PDF tools that never upload your files

Merge, split, compress, redact and convert PDFs right in your browser. Your documents are processed on your device and never sent anywhere — verify it yourself with DevTools.

Why pdfnoupload?

100% private — your files never leave your device

Your files never leave your device

Most online PDF tools upload your documents to a server to process them. We don't — and we can't. Every operation runs locally in your browser using WebAssembly, so your sensitive contracts, IDs and financial documents stay on your machine.

Works offline after the first visit

Once loaded, pdfnoupload keeps working with no internet connection. The app is a Progressive Web App that caches itself, so you can merge or redact a PDF on a plane, in a SCIF, or anywhere you don't trust the network.

Verifiable privacy, not just a promise

Open your browser's DevTools, switch to the Network tab, and process a file. You'll see zero upload requests. Privacy you can confirm with your own eyes beats a privacy policy you have to take on faith.
