Protect / Unlock PDF

Add a password to a PDF to keep sensitive content private, or remove a password from a file you own but no longer need locked. Both options take seconds — upload your file, set or enter the password, and download the result.

Password protection is worth adding to anything containing personal, financial, or confidential information before emailing or sharing it — contracts, invoices, ID scans, and HR documents are common examples. On the flip side, if you have an old password-protected file you created yourself and no longer need locked, unlocking it removes that extra step for future access.

Files are encrypted in transit during processing and automatically deleted within 12 hours, so your password and document content are never stored longer than necessary. No account required.
