About this app

MaiPDF turns ordinary PDFs into protected documents you fully control.

Wrap any PDF into a secure .maipdf file, share it 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 the MaiPDF app, where anti-screenshot protection and a traceable watermark help keep your content from leaking.

KEY FEATURES
• Protect any PDF — turn a PDF into a secure .maipdf document in seconds.
• Anti-screenshot & screen-recording protection on supported platforms.
• Traceable watermark — if a screenshot leaks, trace who opened the file, when, and on which device.
• Access limits — set how many times a document can be opened and when it expires.
• Device binding & limits — control how many devices each recipient can use.
• Reader whitelist — share only with specific email recipients.
• Revoke anytime — cut off access instantly, even after sharing.
• Cross-platform — read protected documents on iOS, Android, macOS and more.

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 who shares sensitive documents — contracts, reports, courseware, designs, financials — and wants them to stay private.
