How to compress an image to 100KB
- Select or drag your photo (JPG, PNG or WebP). You can add several at once.
- The tool automatically tries different quality levels and, only if needed, slightly reduces the dimensions until the file is 100 KB or smaller.
- Click Download. The result is a JPG that is guaranteed to fit the 100 KB limit.
Where is a 100KB limit used?
100 KB is a common upload limit for online job applications, CNIC/passport document uploads, email attachments and CV photos. Many people get the error "file size too large" just before a deadline — this page fixes it in seconds without installing any app.
Tips for the best quality under 100KB
- Crop extra empty space first — fewer pixels means better quality at the same size.
- Photos with plain backgrounds compress much better than busy ones.
- If a form also asks for exact pixel dimensions, use our Image Resizer first, then compress here.
