Frequently asked questions
How strong is the protection?
It uses standard PDF encryption - solid protection against casual access. No password protection stops a determined expert with the file in hand.
Can I remove the password later?
Yes - use our Unlock PDF tool with the password you set.
Do recipients need special software?
No - any standard PDF reader asks for the password and opens the file.
