Compress JPEG to 100KB
Modern phone cameras produce JPEGs of 3–8MB — thirty to eighty times larger than the 100KB many forms accept. This tool is built specifically for that gap: it re-encodes your JPEG at the highest quality that fits under 100KB, reducing dimensions only when absolutely necessary.
100% private — this tool runs in your browser. Your image is never uploaded to any server.

Frequently asked questions
What is the difference between JPEG and JPG?
Nothing — they are the same format. JPG is just the three-letter version of the extension from old Windows systems. Portals asking for either will accept the file this tool produces.
How much can a JPEG be compressed without visible loss?
A camera JPEG can usually shrink 5–10x before quality loss becomes obvious, because cameras encode at conservative settings. Going from 4MB to 100KB (40x) will soften fine detail, but faces and documents stay clearly readable.
Can I compress multiple JPEGs at once?
Yes — use our bulk image compressor, which applies the same KB target to a whole batch and gives you a download link for each file.
