Batch image resizer

Add several JPEG, PNG or WebP images, set a longest side, format and quality, and download the results one by one or as a ZIP. Runs in your browser.

How to use this tool

Add several images.
Set the longest side, format, quality and optional KB target; override the size for single images if needed.
Select Process images; each file shows its own status.
Download files individually or as one ZIP.

When to use it

Shrinking a folder of photos for email.
Preparing many pictures for a website.
Converting a set of images to one format.

Limits

Up to 50 images of 25 MB each, 40 megapixels per image. The longest side is resized with proportions kept; this tool does not crop. Targets in KB are best effort and not available for PNG. Cancel stops after the current image.

Privacy and file handling

Images are processed on your device with canvas. Nothing is uploaded.

Troubleshooting

A failed image shows the reason (empty, wrong type, damaged, too large) and the others still finish. Duplicate names get numbered in the ZIP.

Frequently asked questions

How do I set an exact KB size?
