Drop your PDF onto the tool
Set a password (4–64 characters)
Download the encrypted PDF — it now requires the password to open
How strong is the encryption?
AES-256 — the same standard used by banks and governments. Without the password, the document does not open.
Do you keep a copy of my password?
No. The password is used for the encryption pass and discarded. Files are never stored either — lose the password and the document stays locked.
Is password protection free?
Your first conversion is free with no account. Plans start at $5/month.
Unlock PDF
Remove password protection from your own PDF when you know the current password, leaving a clean, open document.
Redact PDF
Permanently redact PDF text and regions — blackout boxes or exact-phrase search, burned into the file forever.
Add Watermark to PDF
Add a diagonal text watermark to every page of a PDF — CONFIDENTIAL, DRAFT, or any custom text.
