Can you truly prevent PDF forwarding?

You cannot block someone from copying and pasting a link. However, MaiPDF makes forwarding useless by limiting views, requiring email verification, adding watermarks with viewer identity, and preventing downloads — so even if a link is forwarded, unauthorized viewers are blocked or identified.

What happens when the view limit is reached?

When the view limit is reached, the link automatically becomes inactive. Anyone clicking it will see an access denied message. The document owner can increase the limit or generate a new link if needed.

How do watermarks prevent forwarding?

Dynamic watermarks display the viewer's email or IP address on every page. If someone screenshots or photographs the document, the watermark identifies them as the leak source, which strongly deters unauthorized sharing.

Can I revoke access after sharing?

Yes. MaiPDF allows instant access revocation with one click. The shared link immediately becomes inactive, and no further views are possible — even if the recipient bookmarked the link.

Security Best Practices

Updated MaiPDF protection path

Use Online Cloud Sharing for speed; use MaiPDF App DRM when screenshots, forwarding, or device access matter

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.

Fast cloud link

Upload a PDF, share a browser link or QR code, and keep read code / modify code management.

Protected .maipdf file

Package the PDF in the MaiPDF App with local encryption, license rules, expiry, open limits, and revoke control.

App-only protections

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.

Need stronger control?

Create protected .maipdf documents with MaiPDF App DRM.
