About MaiPDF - Secure PDF

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. Support: [email protected] Privacy Policy: https://maipdf.com/privacy.html
