MaiPDF - Secure PDF
DRM Reader for Protected PDFs
Free · Designed for iPad. Not verified for macOS.
MaiPDF turns ordinary PDFs into protected documents you fully control.
Wrap any PDF into a secure .maipdf file, share it only with the people you choose, and decide exactly how it can be read — with access limits, device binding, expiry, and instant revocation. Protected documents open only inside MaiPDF, where anti-screenshot protection and a traceable watermark help keep your content from leaking.
KEY FEATURES
• Anti-screenshot & screen-recording protection — protected documents are blocked or blacked out on capture.
• Traceable watermark — if a screenshot leaks, trace who opened the file, when, and on which device.
• Device binding & limits — control how many devices each recipient can use.
• Access limits & expiry — set how many opens are allowed and when access ends.
• Reader whitelist — share only with specific recipients.
• Revoke anytime — cut off access instantly, even after sharing.
• .maipdf format — opens only inside the MaiPDF app.
HOW IT WORKS
1. Add a PDF and protect it as a .maipdf file.
2. Set your rules: opens, expiry, devices, recipients.
3. Share it — recipients open it securely inside MaiPDF.
4. Manage, revoke, or trace leaks anytime.
Built for anyone sharing sensitive documents — contracts, reports, courseware, designs, financials.
