Why use this 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 to protect pdf in three steps

  1. 1

    Upload the document you need to secure.

  2. 2

    Choose a strong password and set permissions.

  3. 3

    Download the encrypted PDF and share the password separately.

Frequently asked questions

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.
