Frequently Asked Questions About PDF Protection

How secure is the PDF encryption?
Our PDF protection uses military-grade 256-bit AES encryption, which is the same security standard used by:
  • Government agencies - For classified document protection
  • Financial institutions - For banking and transaction security
  • Military organizations - For secure communications
  • Healthcare providers - For HIPAA-compliant patient data
The encryption happens 100% in your browser - files are never uploaded to our servers. We use secure password hashing (SHA-256) and industry-standard cryptographic libraries.
What types of permissions can I set?
You have complete control over PDF permissions:
  • Printing - Allow or restrict printing entirely
  • Copying - Prevent text and image copying
  • Editing - Block document modifications
  • Form filling - Control interactive form access
  • Annotations - Restrict comments and markups
  • Document assembly - Prevent page insertion/deletion
  • Content extraction - Block content copying for accessibility
  • Expiration dates - Set automatic document expiration
Each permission can be individually controlled with owner password protection.
Can I protect multiple PDF files at once?
Yes, batch protection is fully supported! You can upload and protect multiple PDF files simultaneously with the same or different security settings:
  • Same settings - Apply identical protection to all files
  • Individual passwords - Set unique passwords for each file
  • Bulk download - Download all protected files at once
  • Progress tracking - Monitor protection progress for each file
There's no limit to the number of files you can protect in one batch.
What's the difference between user and owner passwords?
Two-level password protection provides enhanced security:
  • User Password - Required to open and view the PDF document
  • Owner Password - Required to change permissions and security settings
You can set:
  • Same password - One password for both opening and permission changes
  • Different passwords - Separate passwords for opening vs. permission changes
  • Owner password only - Document opens freely but needs password for permission changes
This allows flexible security models for different use cases.
Is there a file size limit for protection?
No file size limits! You can protect PDF files of any size. However, for optimal performance and browser compatibility, we recommend protecting files under 100MB at a time. Larger files might take longer to process but will complete successfully. The tool works entirely in your browser, so there are no server upload limits or restrictions.
