Compress an image to 100 KB
A 100 KB limit is popular for profile photos, ID uploads, CMS thumbnails and email signatures.
The target is already set to 100 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 100 KB, counting 1 KB as 1,000 bytes, so the file also passes on systems that count 1,024 bytes.
What fits in 100 KB
As a JPG or WebP, a typical photo of about 800 by 800 to 1,100 by 1,100 pixels fits in 100 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 100 KB at a reasonable size, the list tells you and shows the smallest result.
Tips for reaching 100 KB
- This is a comfortable size for a face photo: sharp on a normal screen without visible blocks.
- For a web thumbnail, WebP at 100 KB shows more detail than JPG at the same size.
- Compress from your original file. Compressing a copy that was already compressed loses more detail.
