How to compress an image to 100 KB

Drop your image above and download — the tool keeps your original dimensions and lowers the JPEG quality by binary search until the file fits just under 100 KB, so it stays as clear as possible. Everything happens on your device; nothing is uploaded. 100 KB holds a readable A4 document scan or a higher-quality photo. Good when a form says “upload below 100 KB”.

FAQ

How do I compress an image to 100 KB?

Drop your image above; the tool lowers the JPEG quality just enough to bring it under 100 KB while keeping it sharp, then you download. If it can't reach 100 KB at full size, use the resize tool to reduce the dimensions first.

Will it reduce the image dimensions?

No — it keeps your original width and height and only reduces the file size. To change dimensions too, use the resize tool.

Is my image uploaded anywhere?

No. Compression runs entirely in your browser; your image never leaves your device.
