About Protect PDF
Set a password and the PDF is encrypted with AES-256, so it can only be opened by someone who has the password. It is a sensible step before emailing contracts, statements or anything personal.
The password is used once to encrypt the file. It is not stored or written to logs, and there is no way to recover it, so keep it somewhere safe.
Choosing a strong password
- Use a long phrase of several unrelated words; length matters more than symbols.
- Don’t reuse a password from an email or bank account.
- Share it separately from the file, never in the same email.
What protection covers
The password controls who can open the file: without it, the contents stay encrypted. Once someone opens the PDF they can read it and could save or share it, so only send it to people you trust.
During processing your file is handled on GlobTool’s server, and the protected copy is deleted automatically after about an hour.
