Why wtfpdf

Nothing is uploaded

Most online PDF tools send your file to their servers. wtfpdf runs the whole PDF engine in your browser, so your files stay on your device.

Works offline

After your first visit every tool keeps working with no connection. You can install wtfpdf as an app from your browser.

Free, with no catches

No account, no watermark, no file size cap and no daily limit. Your device does the work, so there is nothing to ration.

Questions

How can PDF tools work without uploading my file?

wtfpdf is a PDF engine written in Rust and compiled to WebAssembly. Your browser downloads the engine once and runs it on your device, so your files never need to go anywhere.

How can I check that my files are not uploaded?

Open your browser’s developer tools, go to the Network tab and use any tool. You will see no request carrying your file. You can also switch off your network and every tool still works.

Is wtfpdf free?

Yes. Every tool is free, with no account, no watermark and no daily limit.

Does it work on my phone?

Yes. wtfpdf works in modern browsers on iPhone, iPad and Android, as well as on Mac, Windows and Linux.

Is there a file size limit?

There is no limit set by wtfpdf. Very large files are limited only by your device’s memory.
