Frequently Asked Questions
How secure is the PDF protection process?
All PDF processing happens entirely in your browser using client-side encryption. Your documents and passwords never leave your device, ensuring complete privacy and security.
Can protected PDFs be opened on mobile devices?
Yes, protected PDFs use standard security features that work with all PDF readers, including mobile apps, web browsers, and desktop software like Adobe Acrobat.
What happens if I forget the password?
If you forget the password, there's no way to recover it or unlock the PDF. This is by design for security. Always keep a backup of your passwords in a secure password manager.
Can I remove protection from a PDF later?
You can remove protection if you have the permissions password. However, you'll need the original unprotected file or the correct password to make changes to a protected PDF.
Is there a file size limit for PDF protection?
Our tool can handle PDFs up to 100MB in size. For larger files, consider splitting them into smaller documents or using compression before applying protection.
