Frequently Asked Questions
What's the difference between user and owner passwords?
A user password restricts who can open the document. An owner password controls what actions (printing, copying, etc.) are allowed even after opening the document.
How secure is PDF password protection?
PDF encryption uses strong algorithms, but the security largely depends on the password strength. Use a long, complex password for better protection.
Is there a file size limit?
You can upload PDF files up to 10MB in size.
Can I remove the password later?
Yes, you can use our "Unlock PDF" tool to remove passwords, but you'll need to know the current password.
