Add Watermark

Add a text watermark such as DRAFT or CONFIDENTIAL to selected consecutive pages, then inspect a preview before saving.

Add your watermark

1. Choose Add Watermark and open your PDF.
2. Enter Watermark text and choose Position.
3. Set First page and Last page.
4. Choose a Font size from 12 to 96 points, Opacity from 10% to 100%, and Angle from −90° to 90° in 15° steps.
5. Click Preview Watermarked PDF and check every affected page.
6. Click Save PDF… and save a separate copy.

Appearance and limits

The tool overlays black text on the selected pages. Long text shrinks to fit within 24-point margins. Pages outside the range stay unchanged. Use the preview to check overlap with existing text and images.

The watermark is text; image watermarks are not supported. A visible label does not add password protection or prevent copying.

If Preview is disabled, enter nonempty text and check the range and settings. Changing settings clears the prepared result, so preview again before saving.

Use Edit PDF Metadata to change document details instead of adding visible page content.
