Convert PDF to Secure Links

Stop emailing PDF attachments you can't control. Turn any PDF into a secure, trackable link with access controls, watermarks, and real-time analytics.

Create Secure Link How It Works

Email Attachments vs Secure Links

Email Attachments

  • No control after sending — anyone can forward
  • No way to know if it was opened
  • File size limits reject large PDFs
  • Cannot revoke access once sent
  • No watermarks or download prevention
  • Cannot update content after sending

MaiPDF Secure Links

  • Full control — set passwords, limits, expiration
  • Real-time tracking of every view
  • No file size restrictions
  • Revoke access instantly anytime
  • Dynamic watermarks + download prevention
  • Replace PDF without changing the link

Link Security Features

View Limits

Set maximum number of views (e.g., 3, 5, 10). Link automatically expires when the limit is reached.

Instant Revocation

Revoke any link immediately through the control panel. The document becomes inaccessible, no matter how widely shared.

IP Filtering

Restrict access to specific IP addresses/ranges. Useful for office-only document access.

Dynamic Watermarks

Display viewer's email or IP on every page. Deters screenshots and identifies the source of leaks.

Print Control

Disable printing completely. Documents can only be viewed online in the browser.

Download Prevention

Block all download attempts. View-only mode with no local copies possible.

Use Cases

Client Proposals

Share proposals as secure links with view limits and watermarks. Track when clients open them to time your follow-up. Revoke access after the decision is made.

Sales Materials

Share pitch decks with analytics. Know which prospects engage most. Set expiration dates to create urgency and keep materials current.

Course Materials

Distribute study guides and lecture notes with download prevention. Students access online without creating unauthorized copies.

Contracts & Legal Docs

Share contracts with password protection and audit trails. Know exactly when each party reviewed the document.

Frequently Asked Questions

Upload your PDF to MaiPDF, configure security settings (password, watermarks, view limits), then copy the generated secure link to share with recipients.

Only if you allow it. Enable download prevention to force view-only mode where recipients can read the PDF online but cannot save it.

Unlike email attachments, secure links give you ongoing control. You can revoke access, set view limits, track opens, add watermarks, and prevent downloads — none of which is possible after emailing a file.

Yes. Real-time analytics show view count, viewer location, access time, browser, and device information.

The link automatically becomes inaccessible. Anyone trying to open it sees a message that the document is no longer available.

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.
