About SafePDF
Reinventing document privacy through client-side WebAssembly.
0-Byte Egress
For over a decade, users were forced to upload confidential tax returns, medical files, and contracts to unknown cloud servers. We created SafePDF to provide a private, client-side alternative.
100% Free Forever
Traditional converters spend millions on cloud compute servers to process user files. Because SafePDF runs on your device CPU/GPU via WebAssembly, our server costs are nearly zero—allowing us to offer unmetered tools without paywalls.
Native Speed
Powered by modern open-source WebAssembly libraries (pdf-lib, PDF.js, SheetJS, JSZip) to deliver instantaneous processing speeds directly in your browser.
Reinventing Document Privacy
For over a decade, users were forced to upload confidential tax returns, medical files, and contracts to unknown cloud servers. We created SafePDF to provide a private, client-side alternative. SafePDF operates entirely in your browser memory without transmitting a single byte to external servers.
