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.

Can I restrict printing or copying with this tool?

Not currently. This tool protects the PDF from being opened without the password; it does not provide separate printing or copying controls.
