How do I resize multiple images at once?

Upload all images to the Bulk Image Resizer, set your target dimensions, and click process. All files are resized simultaneously in your browser — no server upload needed.

Will resizing change the aspect ratio?

Only if you choose 'crop to fill' or 'stretch to fit.' The default 'maintain aspect ratio' mode scales proportionally, preserving the original proportions.

What image formats are supported?

PNG, JPG, WebP, and GIF. The output format matches the input by default, or you can convert all to a single format during processing.
