How to password protect a PDF
- Choose your PDF.
- Type a password twice. Optionally choose what people may do with the PDF (print, copy, edit…).
- Press Protect and download the encrypted PDF.
Good to know
- AES-256 encryption, the strongest standard PDF encryption, supported by all current PDF readers.
- Restrictions (no printing, no copying…) are respected by most PDF apps, but some ignore them; only the password itself truly protects the content.
- An optional second password allows changing the restrictions later.
- There is no way to recover a forgotten password. Keep it somewhere safe.
Your PDF stays in your browser
The file is read and changed on your device. Nothing is uploaded, so contracts, statements and IDs stay private.
Частые вопросы
How strong is the protection?
With a long password it is very strong: AES-256 can't be broken by guessing. Short, simple passwords can be guessed, so use at least 10 characters.
Is my password sent anywhere?
No. The PDF is encrypted in your browser; neither the file nor the password leaves your device.
Is my PDF uploaded?
No. Everything happens in your browser.
