FAQ
Protect PDF FAQ
Common questions about password protecting PDF files.
What encryption is used?
DocMint uses AES-256 encryption — the same standard used by banks and governments — to protect your PDF.
Can I restrict printing and copying?
Yes. You can set permissions to prevent printing, copying text, and editing while still allowing the document to be opened and read.
Can the password be recovered if forgotten?
No. AES-256 encryption cannot be reversed without the password. Keep your password in a safe place.
Is this tool free?
Yes. DocMint's protect tool is completely free with no signup required.
