Key Features

Complete Access Control for Your PDFs

Password Gate

Set a custom password that recipients must enter before they can open your PDF. Change it any time from your dashboard.

Email Verification Code

Require a one-time code sent to the viewer's email. Know exactly who opened your document with verified identity.

View Limits

Set the maximum number of times your PDF can be opened. Once exhausted, the link automatically deactivates.

Expiration Date

Make your PDF link expire on a specific date. Perfect for time-sensitive proposals, contracts, and offers.

No-Download Mode

Disable the download and print buttons so recipients can only view your document online — never save a copy.

Dynamic Watermark

Overlay viewer-specific watermarks showing email, IP, and timestamp. Deter screenshots and trace leaks.

Access Log

See a full audit trail of every view — who opened, when, from where, and on which device.

Telegram Alert

Get instant Telegram notifications the moment someone opens your protected PDF. Stay informed in real time.

Email Verification in Action

Viewers Must Verify Before Reading

When email verification is enabled, the viewer sees a gate screen asking for their email. A one-time code is sent instantly. Only after entering the correct code can they access the PDF — and their identity is logged.

  • One-time verification code via email
  • Verified viewer identity in access log
  • Works alongside password protection
  • No account required for the viewer
