How it works

Three steps — all on your own device.

Your browser reads only the tiny encryption header — the file itself never leaves your device.

It builds likely passwords from your words & numbers, or a pattern you define, and tests each one.

When a guess reproduces the PDF's stored fingerprint, that's your password — instantly revealed.
