Bulk Image Watermark
Watermark a whole batch with a text caption or a PNG logo. Size and margin are relative to each image, so the mark stays proportional across a mixed set.

Recommended next steps
Good to know
- Text and logo sizes are percentages of the image, so results stay consistent across different resolutions.
- Tiling repeats the watermark across the frame to make removal harder.
- For a logo watermark, a PNG with transparency gives the cleanest result.
Your files stay on your device
This tool decodes and re-encodes images inside your browser using the Canvas API and Web Workers. Nothing is uploaded, and there is no server that could receive your files. Closing the tab discards everything.
