Confidential document security — password protection, watermarks, and access control

Once you email a confidential PDF, you lose all control. It can be forwarded, downloaded, printed, and shared with anyone — and you'll never know. MaiPDF replaces that uncontrolled process with a secure, monitored link that gives you full visibility and control over who accesses your sensitive documents, for how long, and under what conditions.

How It Works

Secure a Confidential PDF in 3 Steps

1

Upload Confidential PDF

Drag and drop your sensitive document. Files are encrypted during upload and stored securely in the cloud.

Security Features

Eight Layers of Document Protection

Password Protection

Require a password before anyone can view the document. Change or revoke the password at any time.

Email Verification

Recipients must enter a one-time code sent to their email. You know exactly who accessed the document.

Dynamic Watermark

Overlay viewer email, IP, and timestamp on every page. If leaked, trace it back to the source instantly.

View Limits

Allow 1–5 views for highly sensitive documents. The link auto-disables after the limit is reached.

Expiration Dates

Set an automatic expiration so the link stops working after the deadline passes.

No Download / No Print

Disable the download and print buttons. Recipients can only view the document in the secure viewer.

Access Audit Trail

See who viewed the document, when, how many times, and from what device — all in real time.

Revoke Access

Disable any sharing link instantly. Even forwarded links stop working the moment you revoke.

FAQ

Frequently Asked Questions

Upload your confidential PDF to MaiPDF and configure layered security: enable password protection, set view limits (1–5 for highly sensitive docs), add dynamic watermarks, set an expiration date, and disable downloads. Share the controlled link through a secure channel and send the password separately. Monitor access through the analytics dashboard.

Yes. With MaiPDF you can disable any sharing link instantly from your dashboard. Once revoked, the link stops working immediately — even if it was forwarded to others. This is impossible with traditional email attachments or cloud storage links.

MaiPDF's dynamic watermarks overlay the viewer's email address, IP address, and timestamp on every page of the document. If someone takes a screenshot or photo of the content, the watermark identifies exactly who leaked it. This acts as both a deterrent and a forensic tool.

Any PDF document: legal contracts, financial reports, investor updates, HR records, salary offers, research papers, product roadmaps, board meeting minutes, medical records, insurance documents, and any other sensitive business files.
