Watermark images in batch
Add your images, choose a text watermark or upload your own logo, then set position, opacity, scale and (for text) color and rotation. One image is previewed before you run the batch.

JPG · PNG · WebP — files stay on your device
How to use it
- Add the images to watermark.
- Choose text or a logo image; set position, opacity and scale.
- Check the first-image preview, then run the batch and download.
Limits & formats
Up to 20 images per batch, each up to 20 MB and 25 megapixels. Output keeps the input format (JPEG gets no transparency — pick PNG to keep it). Watermark text uses your device's system fonts. A watermark marks ownership; it does not by itself prevent someone from cropping it out.
Privacy
Your images are processed locally in this browser tab. YYSI servers never receive your files. Only anonymous usage counters (tool name, success or failure, rough size range) are recorded.
