What is the simplest secure PDF sharing method?

Secure Links are the simplest method. Upload your PDF, configure access settings (view limits, expiration, password), and share the generated link. No recipient setup needed.

Can I combine multiple sharing methods?

Yes. MaiPDF allows layering security. You can combine a secure link with email verification AND domain restriction for maximum protection. Additional controls like view limits, expiration, and watermarks can also be added.

Secure PDF Sharing Methods: Links, Email Verification & Domain Lock

Q: How does email verification for PDF access work?

When email verification is enabled, viewers must enter their email address before accessing the PDF. MaiPDF sends a verification code to confirm identity, creating an audit trail of exactly who viewed the document.

Q: Can I restrict PDF access to a specific company?

Yes. Domain restriction limits PDF access to viewers with email addresses from specific domains (e.g., @company.com). Only verified users from approved domains can view the document.

Q: Which method should I use for legal documents?

For legal documents, use email verification combined with domain restriction. This ensures verified identity, creates an audit trail, and limits access to authorized organizations — meeting compliance requirements.

Security Best Practices

Match Method to Risk

Use Secure Links for low-risk, Email Verification for medium-risk, Domain Restriction for high-risk.

Set Expiration Dates

Always set an expiry. Even trusted documents should not live forever on shared links.

Enable Watermarks

Dynamic watermarks show viewer identity and deter unauthorized redistribution.

Monitor Analytics

Review access logs regularly. Revoke links immediately when access is no longer needed.

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?
