Everything happens locally in your browser. Your PDF is processed on your own device using your browser's built-in capabilities, so it is never uploaded to a server and never leaves your computer. That makes PDF Password fast — there is no upload or download wait — and private by default.
Because it is web-based, PDF Password works on any operating system — Windows, macOS, Linux, Android, and iOS — straight from your browser, with nothing to install.
