Reduce an image to under 100 KB
Upload the image and set the target size to 100 KB. The tool lowers the quality — and the dimensions if needed — step by step until the file fits. You see the result right away and can compare it with the original.

Where tight limits appear
Government portals, job applications, exam registrations and visa forms often limit photos and signatures to 50–200 KB. A phone photo is usually 2–5 MB — 20 to 50 times too large.
Size first, then quality
For a passport photo or a signature, 600–800 pixels are enough. Reducing the dimensions first with Resize images keeps much more quality than heavy compression of a huge image.
| Use | Suggested size |
|---|---|
| Signature | 400–600 px wide |
| Profile / passport photo | 600–800 px on the long side |
| Document photo | 1200–1600 px on the long side |
Tips
- WebP is usually much smaller than JPG and PNG at the same quality.
- PNG is lossless — for photos, converting to JPG or WebP pays off.
- Dimensions too large? Also resize the image.
