What Watermark Image does

Use Watermark Image when you need to mark product photos before sending previews to clients.

When to use it

  • Mark product photos before sending previews to clients.
  • Add a logo or ownership note to social and marketplace images.
  • Label drafts so unfinished assets are not reused by mistake.

How to use it

  1. Add the image and choose text or logo watermark mode.
  2. Set position, opacity, and size so the mark is visible but not destructive.
  3. Export and check both bright and dark areas of the image.

What to check

  • Watermarks can be cropped out if they sit only on the edge.
  • Keep an unmarked master image for future edits.
