How does the 20KB image resizer work?

The tool re-encodes JPG and WebP output at progressively lower quality and compares the result with 20KB. Exact size depends on image detail and browser encoding. If the target cannot be reached without shrinking the image dimensions, the result explains that instead of silently resizing it.

Common uses

Prepare a smaller image for a form with a stated file-size limit.
Reduce storage or transfer size while keeping the original pixel dimensions.

Privacy and limitations

Your image stays in this browser. Highly detailed images may remain above 20KB unless their dimensions are explicitly reduced with the Image Resizer.
