Frequently Asked Questions
🔐 Which protection method should I choose?
For confidential files, use password protection with encryption. To allow reading but block reuse, add permission restrictions. For maximum security, combine all three methods.
🆓 Are all these tools included?
Yes. PDF Agile includes password protection, copy restrictions, and editing locks. No cloud upload, no subscription required.
🔒 What's the difference between encryption and permissions?
Encryption controls who can open the file (Bank-grade). Permissions control what users can do after opening (copy, print, edit). For maximum security, use both together.
