How to batch resize and watermark

Resize a whole batch of images to a consistent size and stamp the same watermark in the same spot on every one — text or a logo. Up to 20 images at a time, all in your browser (nothing is uploaded).

Steps

1. Add images — up to 20 at once (extra files beyond 20 are ignored to keep things fast).
2. Set the longest side (256–2048 px). Each image keeps its aspect ratio.
3. Configure the watermark:
   • Type: Text or Image / logo.
   • Text — choose the font; or Image — upload a logo and set its size (% of each image).
   • Position — any of 9 anchor points.
   • Opacity — how strong the watermark is.
4. Resize & download ZIP. Files are named name_<width>x<height>.png.

Your settings are saved

Your watermark settings (type, text/logo, font, position, size, opacity) are remembered in this browser, so the next time you open the tool they're already filled in. Change anything and the new value is used and saved.
