Mark your images as yours
A watermark deters people from reusing your photos without credit and labels documents as DRAFT or CONFIDENTIAL. This tool overlays your text across an image with full control over size, opacity, colour and placement.
Use a faint diagonal or tiled watermark to cover the whole image, or a small corner mark for a subtle signature. Everything is rendered locally.
How to use it
- Drop your image.
- Type your watermark text and choose placement, size, opacity and colour.
- Click Add Watermark and download.

Frequently asked questions
Can I tile the watermark across the whole image?
Yes - choose the Tiled placement to repeat the text diagonally across the entire image, which is hardest to crop out.
Will it keep transparency?
PNG and WebP outputs keep transparency; JPG is placed on a white background as usual.
Are my images uploaded?
No. The watermark is drawn in your browser, so your images never leave your device.
