- 03
Download and review
Run the watermark action. Inspect every page in the downloaded copy, especially pages with different dimensions.
Settings
- Position
- Choose center, diagonal, top-left, top-right, bottom-left or bottom-right. The watermark is applied to every page.
- Size and opacity
- Font size spans 12–120 points and opacity spans 5–100%. Lower opacity makes the text less prominent.
Help and limitations
Can I add a logo?
The current working watermark feature is text only; it does not add an image or logo.
Can I choose a custom angle?
The diagonal preset uses a fixed angle. There is no separate angle control.
Before you use the output
Long text or large lettering can extend beyond page edges, especially at corner positions. Check the export; a watermark does not prevent copying.
