Protect photos with a semi-transparent text watermark, placed once or tiled across the image.

What the Image Watermark does

Protect your photos with a text watermark such as your name, website or copyright notice. Place it in a corner or tile it diagonally across the whole image so it is harder to crop out. Batch up to 20 images with the same watermark.

Placement (nine positions or tiled), Text size, Color and Opacity.
Tile angle for the tiled pattern.
