Key Features

Powerful Watermark Protection

Dynamic Watermark (Viewer-Specific)

Each viewer sees a unique watermark containing their identity. If a screenshot leaks, you know exactly who shared it.

Custom Text

Add your company name, "CONFIDENTIAL", document ID, or any custom text as a watermark across every page.

IP & Timestamp

Automatically embed the viewer's IP address and exact access timestamp into the watermark for forensic tracing.

Leak Tracing

If a watermarked document surfaces online, the embedded viewer data lets you identify the source of the leak instantly.

Screenshot Deterrent

Visible watermarks discourage screenshots and photos. Viewers know their identity will be captured in any leak attempt.

No-Download Mode

Combine watermarks with disabled download and print buttons for maximum document protection.

Access Analytics

Track every open alongside watermark data — see who viewed, when, from where, and correlate with the unique watermark.

Dynamic Watermark Example

Every Viewer Sees a Unique Mark

The watermark is rendered at view time, not baked into the PDF file. This means each viewer sees their own email, IP, and timestamp overlaid on every page — making every copy uniquely traceable.

  • Viewer email embedded in watermark
  • IP address and timestamp included
  • Adjustable opacity and positioning
  • Appears on every page automatically

FAQ

Frequently Asked Questions

A dynamic watermark is generated at view time and contains viewer-specific information such as their email address, IP address, and the exact timestamp. Unlike static watermarks, each viewer sees a unique mark that can be traced back to them.

Yes. MaiPDF allows you to choose which fields appear — email, IP, timestamp, or custom text. You can also adjust position, opacity, and font size.

While no software can technically block a screenshot, dynamic watermarks act as a strong deterrent. If a screenshot is taken, the viewer's identity is visibly embedded in the image, making unauthorized sharing traceable.

Yes. Because each viewer sees a unique watermark with their identity, any leaked screenshot or photo can be traced back to the specific person who captured it.

Basic watermarking with custom text is available on the free tier. Dynamic watermarks with viewer-specific fields like email and IP are available on paid plans.
