About quietpdf
quietpdf is a collection of PDF tools that run entirely in your browser. We built it on one principle: your files should never leave your device.
Conventional online PDF tools upload your documents to a server to process them. We don't. Every operation — merging, splitting, compressing, converting — happens locally using WebAssembly and JavaScript. Nothing is uploaded, and there's nothing to sign up for.
Because the code is public, you don't have to take our word for it. You can read exactly what runs, and you can watch your browser's Network tab to confirm your file stays put.
