Compress Image to 100 KB

Reduce any photo to 100 KB or less — no upload, no watermark, 100% private

100% private — images are compressed inside your browser and never uploaded to any server.

How to Compress an Image to 100 KB

Choose your image above and click Compress — the tool automatically finds the highest possible quality that fits under 100 KB. It first tunes JPEG compression quality with a binary search, and only reduces the image dimensions if the size target can't be met by quality alone. You see the original size, the final size and the output dimensions, then download the result with one click. Multiple images can be processed in the same batch.

The 100 KB limit is common for profile photos, document scans on application portals, and email attachments on slow connections. It's also the sweet spot for web images that must load fast without visible quality loss. The output is a standard JPG that every form portal, email system and website accepts.

Completely private — no upload

Unlike most online compressors, this tool never sends your photo to a server. Compression happens inside your browser using the canvas API, so personal photos, ID images and documents stay on your device from start to finish. There's no watermark, no signup and no file limit per day.
