SafeTools PDF Studio FAQ

Everything you need to know about our privacy-first document ecosystem.

Are my PDFs uploaded to any server?

Absolutely not. SafeTools uses WebAssembly (WASM) to process PDFs directly on your device. Your data never leaves your browser.

What engines do you use?

We use a combination of QPDF, MuPDF, and custom WASM binaries to ensure the highest performance and compatibility.
