Target Compressor: Max 100 KB
Add your images to compress them automatically to 100 KB or less.
The 100 KB limit is one of the most common file ceiling requirements across online job applications, civil service portals, passport upload tools, and school admission forms.
Our image compressor uses iterative binary quality search to adjust JPEG and WebP encoding parameters so your photo lands at or under 100 KB without unnecessary quality loss.
Why the 100 KB Limit is Common
- Online visa, passport, and exam application portals enforce strict 100 KB maximum file thresholds.
- Corporate email servers and web forms often reject photos exceeding 100 KB.
Tips for Hitting 100 KB
- Crop away extraneous background area before compressing to keep essential details sharp.
- Use JPG or WebP instead of PNG when compressing photos to 100 KB.
