Complete PDF Security Features

Eight layers of protection for your sensitive documents

Basic

Password Protection

Require a password before anyone can view your PDF. Set unique passwords for each document or sharing link.

Basic

View Count Limits

Set the maximum number of times a document can be accessed. The link automatically expires after the limit is reached.

Advanced

Email Verification

Require recipients to verify their email address before accessing your PDF. Know exactly who viewed your document.

Advanced

Dynamic Watermarks

Add watermarks that display viewer-specific information (email, timestamp, IP) to deter unauthorized screenshots and sharing.

Advanced

Download Prevention

Disable download and save options. Recipients can only view the document in their browser — no local copies can be made.

Advanced

Print Restrictions

Prevent viewers from printing your PDF document. Combined with download prevention, this stops physical redistribution.

Enterprise

IP-Based Access Control

Restrict document access to specific IP addresses or ranges. Ideal for corporate environments with fixed network infrastructure.

Enterprise

Real-time Analytics

Monitor every access attempt with detailed analytics — timestamps, device types, geographic locations, and engagement metrics.
