How It Works
Open MaiPDF and upload your document (up to 100 MB). Sign in or use the quick upload in the header.
Toggle the dynamic watermark option in settings. Configure expiration, access limits, and Telegram alerts alongside it.
Distribute via link or QR code. Every viewer sees a unique watermark with their identity embedded on each page.
Watermark in Action
When a recipient opens your watermarked PDF, MaiPDF renders a unique overlay on every page in real time. The watermark includes a QR code that encodes the viewer's email or session identifier, their IP address, and the exact access timestamp.
Because the watermark is generated per viewer and per session, no two people ever see the same mark. If a screenshot or photograph of the document surfaces, scanning the QR code instantly reveals who accessed it, when, and from where.
You control the watermark opacity, position, and supplementary text through the MaiPDF settings panel — balancing readability with security.
Capabilities
Each viewer gets a unique QR code on every page, encoding their identity and session data for full traceability.
The watermark shows the viewer's email or name directly on the page, making leaks immediately attributable.
Every watermark embeds the viewer's IP address and the exact date and time of access for forensic evidence.
The access log records the browser, operating system, and device type alongside the watermark data.
If a document surfaces outside its intended audience, scan the QR code to identify the exact source of the leak.
Visible watermarks discourage recipients from capturing and sharing the document, as their identity would be exposed.
Add your own text alongside the dynamic data — company name, confidentiality notice, or any custom message.
Combine QR watermarks with download prevention, view limits, expiration, FenceView, and password protection.
