Use online view-only PDF sharing when you need fast no-download links. Upgrade sensitive files to MaiPDF App DRM / .maipdf when screenshots, device access, license revocation, and watermark tracing matter.

How It Works
Open MaiPDF and upload your PDF from the header, or log in to manage files from your dashboard.
Turn off download and print, disable copy and selection, add FenceView, watermarks, expiration, and view limits.
Distribute a secure link or QR code. Recipients view in the browser under the restrictions you set.
Key Features
Deliver content in a secure viewer so recipients stream the document instead of saving a portable file.
Remove print routes from the viewer so the document stays on screen and off paper trails.
Block text selection and clipboard copy so content cannot be lifted with a simple highlight and paste.
Use browser deterrence for quick sharing, then move high-risk files into the MaiPDF App protected viewer when screenshots are the main concern.
Overlay viewer-specific identifiers on each page to trace leaks and deter unauthorized photography.
Package sensitive PDFs into protected .maipdf files so access stays controlled by the App license instead of the copied file alone.
Cap opens per link so shared URLs cannot be reused endlessly across unknown recipients.
For App DRM files, manage open limits, expiry, device checks, and revocation from the license layer.
Choose the right protection level
For everyday secure sharing, MaiPDF online delivery keeps the original PDF away from a direct attachment: recipients open a controlled link or QR code, while you manage download, print, copy, expiry, watermark, and access records.
When the real risk is screenshots, forwarded copies, or a file that keeps circulating after download, move the workflow to the MaiPDF App. The App packages a protected .maipdf file and checks license rules before rendering inside a protected viewer.
.maipdf files.
Browser view-only sharing for fast controlled links.
App protected viewer for high-risk .maipdf files.
Comparison
Password-only rows reflect typical consumer PDF tools. Online sharing controls links and viewer behavior; App DRM is the stronger path when you need protected .maipdf files, license checks, and screenshot-aware app viewing. A separate camera can still record any screen.

Updated MaiPDF protection path
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.
Upload a PDF, share a browser link or QR code, and keep read code / modify code management.
Package the PDF in the MaiPDF App with local encryption, license rules, expiry, open limits, and revoke control.
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.
