Use this page to pick the right path: a quick online PDF link, a QR code, a controlled browser viewer, or MaiPDF App DRM / .maipdf when screenshots and forwarded copies are the real risk.
Link + QR Access control App DRM for screenshots
Method Matrix
| Method | Best for | What to enable | Main risk |
|---|---|---|---|
| Secure Link | Proposals, sales decks, client docs | Password + expiry + watermark | Link forwarding |
| QR Sharing | Events, brochures, printed handouts | Expiry + optional view limits | Public scan access if unrestricted |
| Email Invite | Formal one-to-one delivery | Email verification + access records | Attachment version drift |
| Controlled Viewer | Confidential or internal documents | No-download + watermark + view limits | Overly strict settings hurt usability |
MaiPDF App DRM / .maipdf |
Paid training, contracts, investor decks, sensitive files where screenshots matter | Protected viewer + license rules + revoke + watermark trace | No software can stop someone filming the screen with another phone |
Decision point
For most PDF sharing, Online Cloud Sharing is the right first choice: upload once, send a link or QR code, set expiry and watermarks, then check access records.
Move to MaiPDF App DRM when the file itself must remain license-controlled after it leaves your browser workflow. The App packages a protected .maipdf file and opens it inside a protected viewer with license checks, revocation, and watermark tracing.
Fast links, QR codes, expiry, watermarks, and access logs for everyday sharing.
Screenshot-sensitive PDFs, forwarded copies, device rules, license revoke, and traceable leaks.
Honest boundary: no software can stop a separate phone camera, but App DRM makes casual capture and copied files much less useful.
How It Works
Upload file and define audience.
Set expiry, limits, and watermark.
Send link or QR and track opens.
Workflow Diagram
Access Records
Use Read Code + Modification Code to query access records. This is the fastest way to audit shared links.
Practical Controls
Baseline protection for client access links.
Limit exposure window for temporary docs.
Restrict repeated open attempts.
Discourage leaks with viewer identity overlay.
Execution
Playbook
| Scenario | Recommended controls | Follow-up action |
|---|---|---|
| Sales proposal | Password + 7-day expiry + watermark | Review open timeline before pricing follow-up |
| Investor update | Verified viewer + no-download + revoke switch | Disable access after board cycle ends |
| Training materials | QR sharing + view limits + printable allowed | Track completion and refresh old versions |

Use Online Cloud Sharing to upload the PDF, create a link or QR code, and send it through email, chat, or a website. Add a password or expiry date when the audience is known but not highly sensitive.
Use browser sharing plus view analytics so you can see whether a prospect opened the file, which link they used, and whether follow-up is needed.
Use MaiPDF App DRM and package the document as a .maipdf file when forwarding, copying, device control, or post-share revocation matters more than convenience.
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.
