How this image compressor works
LeanPix compresses images entirely inside your browser — no server upload, no waiting, no daily limit. Drop your images above and they're processed locally on your device, then downloaded straight to your disk.
Most compressors upload your file to their server first. LeanPix skips that step entirely: there is no server that receives your images, so you can disconnect from the internet after the page loads and keep working.
It's free with no sign-up, no watermark, and no card required. The only limits — 25 MB per image, 30 per batch — are your browser's memory, not a service cap.
