What 30KB means
30KB is approximately 30,720 bytes. This target is commonly useful for upload forms and websites with a specific file-size limit.
What if my image is already below 30KB?
If the original file is already smaller than 30KB, recompressing it is usually unnecessary and can reduce quality. Keep the original unless you also need a different format or dimensions.
Why the result may not be exactly 30KB
Image detail, dimensions, format and transparency all affect compression. The tool aims to stay at or below the target while preserving as much usable quality as practical. Very detailed images may need smaller pixel dimensions to reach a tiny target.
JPG, PNG and WebP quality
JPG usually reaches very small targets more easily because it uses lossy compression. PNG is better for transparency and sharp graphics but can remain larger. WebP often provides a useful balance between quality and file size while supporting transparency.
