About Bulk Image Resizer.

Batch resizing in your browser

Resize multiple images using one set of settings. Width and height modes preserve proportions. Exact dimensions offer contain, cover and stretch fitting. Percentage scaling applies separately to each source image.

Transform and export

Rotate in 90-degree steps, flip horizontally or vertically, and apply grayscale or sepia. Export JPG, PNG or WebP, or preserve these source formats with Original. Other Original inputs export as PNG. Transparent outputs are available with PNG and WebP.

Target file size

Target-size mode adjusts compression and, when necessary, pixel dimensions to stay under the requested size. Results depend on the source and format; exact byte equality is not guaranteed.

Local processing

Files stay on your device. Animated images become a still frame. Batch and dimension limits protect browser memory; review the output before downloading.
