Compress JPEG to 100KB
Compressing a JPEG to 100KB is the most common upload requirement — job portals, visa and passport applications, and government forms frequently cap photos at 100KB. This tool automatically finds the best quality under that cap, with nothing uploaded to any server.

What fits in 100KB — realistic expectations
100KB comfortably holds a 1200–1600px photo at good quality (roughly 60–75%), which is why so many application portals use it as a ceiling. Passport-style photos, scanned ID documents, and CV headshots all fit well within it.
Very large originals may still need a resize first — a 6000px scan can't fit 100KB without extreme degradation. If the result comes back over target or visibly rough, resize to about 1500px on the long edge and run it again; document scans also compress better with even lighting and a flat background.

Frequently asked questions
Why do so many forms require images under 100KB?
It keeps storage and processing predictable for high-volume systems. 100KB holds a 1200–1600px JPEG at good quality — plenty for identification and document purposes.
Will my photo still look good at 100KB?
For images up to ~1600px, yes — quality typically lands at 60–75%, which is visually clean. Larger originals should be resized first for the best result.
Is my image uploaded to compress it?
No. The size search and compression run entirely in your browser — your image never leaves your device.
