PDF Security & Encryption Auditor
Drop in a PDF and get an instant security verdict: is it encrypted, with which algorithm (RC4 40/128-bit, AES-128 or AES-256), what key length and permissions, and whether it leaks metadata, JavaScript or embedded files. Everything is analyzed on your device — the file never leaves your browser. Built for auditors, compliance teams and anyone who has to prove a document is protected.
Run the audit
Runs entirely in your browser — nothing is uploaded; your answers are saved only on this device.
Frequently asked
Does my PDF get uploaded?
No. The file is read and analyzed entirely in your browser; nothing is sent to any server.
Can it open a password-protected PDF?
It audits the encryption without cracking it — it reports the algorithm, key length and permissions, not the contents.
What does it flag as a risk?
Weak/absent encryption, permissive permissions, exposed author/metadata, embedded JavaScript, and embedded files — each with plain-language guidance.
