🛡️

PDF Security & Protection

How can I prevent someone from editing my PDF?
You can prevent PDF editing using offline software like Adobe Acrobat Pro to set permissions, or use online platforms like MaiPDF that provide dynamic access controls. Learn more in our guides: [Offline PDF Edit Protection](/posts/prevent-pdf-editing-offline-complete/) and [Online PDF Protection](/posts/prevent-pdf-editing-online-complete/).
What's the difference between password protection and DRM?
Password protection is a basic security measure that requires a password to open the file, but once opened, the file can be copied or shared. DRM (Digital Rights Management) provides comprehensive protection including copy prevention, print restrictions, access tracking, and dynamic watermarks. [Learn about PDF DRM here](/posts/free-pdf-drm-online/).
Can I revoke access to a PDF after sharing it?
Yes! With online PDF protection platforms like MaiPDF, you can revoke access instantly, even after the document has been shared. This is one of the key advantages over traditional PDF encryption. [See how it works](/posts/online-pdf-edit-protection-guide/).
How do I stop people from forwarding my PDF files?
The best way is to use protected links instead of sending PDF files directly. Services like MaiPDF allow you to create secure links with access controls, view limits, and expiration dates. [Complete guide to preventing forwarding](/posts/stop-pdf-forwarding-tips/).
Is online PDF protection more secure than offline encryption?
Online protection offers advantages like real-time access control, dynamic permissions, and comprehensive tracking that offline encryption cannot provide. However, both have their place depending on your needs. [Compare both methods](/posts/pdf-comparison/).

Can I track QR code scans?
