Local · No uploadJJPG compression reduces file size by discarding some image data. The key is finding the balance between size reduction and visible quality loss. Near-lossless compression uses perceptual models to remove data that the human eye cannot easily detect — the result looks identical but is significantly smaller.
This tool uses MozJPEG-quality encoding when available, falling back to standard browser JPEG encoding. The compression is tuned for web delivery: smaller files mean faster page loads, lower bandwidth costs, and better user experience. For most photos, 80-85% quality produces files that are 40-60% smaller with no visible degradation.
Unlike many online compressors that upload your photos to a server, this tool runs entirely in your browser. Your images stay on your device. This also means there is no queue, no registration, and no file count limit — just drop, compress, and download.

JPG is always lossy by definition. However, "near-lossless" compression removes only data that is invisible to the human eye, so the result appears identical to the original.
Typical photos compress 40-60% smaller with no visible quality loss. Highly detailed images (screenshots, text) may show artifacts at high compression levels.
