Use this for quick sharing
Online Cloud Sharing
Create a secure browser link or QR code, set view limits, add watermarks, track opens, and keep a modify code for later changes. This is the fastest path for normal proposals, reports, class handouts, and public-facing materials.
Use this for sensitive files
MaiPDF App DRM
Package the PDF as .maipdf, open it in the protected viewer, enforce license rules, bind access to identity/devices where enabled, revoke access, and use screenshot-aware controls on supported platforms.
Important truth
No website can promise 100% screenshot blocking
A browser page can disable selection, hide controls, or add watermarks, but it cannot fully prevent screenshots or someone taking a photo with another device. MaiPDF positions anti-screenshot as an App DRM layer: make casual capture harder, keep access revocable, and show traceable identity/time/license watermarks if a leak happens.
Open sensitive files inside MaiPDF instead of a normal PDF reader.
Use platform security APIs where supported and show clear limitations.
Tie access to accounts, devices, open counts, and expiration policies.
Change license status and use watermark information for leak investigation.
Recommended workflow
From PDF link to protected .maipdf
- Use Online Cloud Sharing when the reader only needs convenient browser access.
- Switch to MaiPDF App DRM when the file is confidential, paid, internal, or contract-level.
- Create the
.maipdffile, set expiry / open limits / identity or device rules, then send the protected package. - Readers open the file in MaiPDF protected viewer; the owner can manage licenses and revoke access later.
