Your PDF is processed locally in your browser.

PDFSimplify processes documents on your device using client-side WebAssembly and Web Workers. No document data is transmitted to our servers or external cloud services during processing.

How Unlock PDF Works in Your Browser

Decrypts the document using the provided password locally in your browser and re-saves the document without security restrictions.

Why client-side processing is more private:

Unlike conventional online converters, your documents never traverse external networks to third-party processing servers. Everything happens inside your local machine’s memory.
