Why use this free tool

Payroll, contracts and medical records should not sit unprotected in an inbox. Set an open password and the file is encrypted with AES-256, the same standard used by Acrobat, so it cannot be read without the password.

How does the free protect pdf work?

1
Upload the document you need to secure.
2
Choose a strong password and set permissions.
3
Download the encrypted PDF and share the password separately.

अक्सर पूछे जाने वाले प्रश्न

Which encryption is used?

AES-256 with revision 6 handlers, supported by every current PDF reader.

Can you recover my password later?

No. The password is never stored on our side. If you lose it, the document cannot be opened.

Can I stop people copying text?

Yes. Text extraction and editing are blocked by default, and you can also decide whether printing is allowed.
