How it works
A watermark can identify a document as a copy, draft or internal version. Enter a short label that fits across the page.
Choose the right inputs
Text is drawn diagonally with the selected opacity. Lower opacity makes the label less intrusive while still remaining part of the page content.
Understand the output
The built-in font encodes supported Latin characters. Unsupported glyphs produce an error rather than silently replacing the watermark with missing-character boxes.
Use the result carefully
Watermarks are visual identifiers, not a mechanism to stop copying. They also do not remove, redact or authenticate the underlying document.

The default COPY label uses 48-point text at 20% opacity, leaving the source text selectable underneath.
