Compress an image to 150 KB
A 150 KB limit suits product thumbnails, blog images and forms that allow a slightly larger scan.
The target is already set to 150 KB. The tool tries the highest quality first and lowers it step by step until the file fits. It shrinks the pixel size only when quality alone cannot get under the limit. It aims slightly below 150 KB, counting 1 KB as 1,000 bytes, so the file also passes on systems that count 1,024 bytes.
What fits in 150 KB
As a JPG or WebP, a typical photo of about 1,000 by 1,000 to 1,400 by 1,000 pixels fits in 150 KB. Screenshots, logos and scans of text behave differently: flat colors compress very well, and fine texture or noise compresses poorly. If the file cannot reach 150 KB at a reasonable size, the list tells you and shows the smallest result.
Tips for reaching 150 KB
- Photos at this size keep fine detail such as hair and the lettering on signs.
- If the picture is a screenshot with flat colors, PNG with 128 colors is often smaller than a JPG and keeps text crisp.
- Compress from your original file. Compressing a copy that was already compressed loses more detail.
