Key Features

Full Control Over Every Shared PDF

No-Download Viewer

Recipients view in the browser without a download or save button, so the original file never leaves your control.

Expiration Dates

Set a date or countdown timer. Once expired, the link stops working automatically — no manual revocation needed.

View Limits

Cap total opens per link so shared URLs cannot be redistributed and reused beyond your intended audience.

Password Protection

Require a password before the document can be viewed, adding a gate even if the link is accidentally forwarded.

Email Verification

Require viewers to verify their email address before access, so you know exactly who opened the document.

Dynamic Watermark

Overlay viewer-specific details like email, IP, and timestamp on every page to deter leaks and trace any capture.

Telegram Alerts

Get instant notifications on Telegram whenever someone opens your shared PDF, with device and location info.

Access Audit Log

Review a full history of opens with timestamps, IP addresses, device types, and geographic locations.

Why It Matters

Email Attachments Aren't Secure

Once you email a PDF, you lose all control. Anyone can forward it, download it, or print unlimited copies. MaiPDF replaces attachments with a controlled viewer link that enforces your security policy in the browser.

  • No file ever leaves your control
  • Revoke access at any time with one click
  • Works on every device and browser

FAQ

Secure Sharing Questions

No. MaiPDF delivers your document through a secure browser viewer instead of a downloadable file. Download, save, and print buttons can be disabled so recipients can only view the content online.

You set a date or time window when uploading. After that point the link automatically stops working, and the document cannot be accessed by anyone — even if they bookmarked the URL.

A view limit caps the total number of times your link can be opened. Once the limit is reached the document becomes inaccessible, preventing uncontrolled redistribution.

Yes. MaiPDF can overlay viewer-specific details such as email address, IP, and timestamp on every page so you can trace any leak back to the person who captured it.

MaiPDF supports PDF uploads up to 100 MB. For larger documents, consider compressing or splitting the file before uploading.
