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.

Updated MaiPDF protection path

Use Online Cloud Sharing for speed; use MaiPDF App DRM when screenshots, forwarding, or device access matter

SendPDFOnline pages now describe MaiPDF as a two-level product family: Online Cloud Sharing creates quick browser links and QR codes, while the MaiPDF App creates protected .maipdf packages for sensitive PDFs that need App DRM controls.

Fast cloud link

Upload a PDF, share a browser link or QR code, and keep read code / modify code management.

Protected .maipdf file

Package the PDF in the MaiPDF App with local encryption, license rules, expiry, open limits, and revoke control.

App-only protections

Use protected viewer, device binding, screenshot-aware controls, watermark trace, and license management where supported.

No web page can fully stop screenshots. MaiPDF App DRM is positioned as the stronger path: reduce casual copying, bind access to identity/devices, revoke licenses, and trace leaks with visible watermark information.

Need stronger control?

Create protected .maipdf documents with MaiPDF App DRM.
