Compress to 100 KB

Add an image to enable compression.

Compress an image to 100KB free, directly in your browser. 100KB is the most common upload limit on the web — application forms, job boards, forum avatars, email signatures and CMS media fields all use it — and a modern phone photo of 3–8MB sails way past it.

This tool automatically finds the highest JPEG quality (and, when needed, the right dimensions) that fits under 100KB, so you don't have to guess with a quality slider and re-export five times. It runs entirely on your device: your image is never uploaded, there's no sign-up, and the compressed JPG downloads instantly.

Frequently asked questions

How do I compress a photo to exactly 100KB?

Just drop the photo in and press compress — the tool automatically searches for the best JPEG quality that lands under 100KB, shrinking dimensions only when it has to. There's no slider to fiddle with and no trial-and-error re-exporting.

Will my image lose quality at 100KB?

Slightly, but 100KB is a comfortable budget for most photos at screen resolution — the result usually looks identical to the original unless you zoom right in. The tool always picks the clearest version that fits the limit.

Is my image uploaded during compression?

No. Everything runs in your browser using the Canvas API, so the photo never leaves your device. The tool is free, with no account and no watermark.
