What does Watermark Image do?
Watermark Image is a free online tool that can add a text watermark to an image. The PNG result from Watermark Image is a separate copy to inspect before you use it elsewhere. One possible use is sample photos visibly marked before a review.
Image watermarking adds your chosen text near the bottom-right of a picture. It is useful for a visible sample label or credit line, and the form lets you set the font size.
The text is drawn with a dark backing and light lettering so it can stand out, but placement and contrast still need review. A watermark is a visible annotation, not a technical restriction on copying or editing the image.
The mark is placed near the bottom-right of the image. Font size and wording affect how much of the source it covers.
A dark backing helps white text stand out. It is still a visible mark that can be cropped or edited. Check it at the final display size before sharing a sample.
