Most images leaving a camera or design tool are far larger than they need to be on the web. A 4 MB PNG from Figma, a 6 MB photo from an iPhone — neither needs to be that size to look sharp on screen. This tool applies smart lossy compression and optional downscaling, then gives you back a file that's typically 60–80% smaller with no visible difference at normal viewing sizes. Everything runs in your browser via WebAssembly; the original file is never uploaded anywhere.
Unlike other sites, we process your photos locally. Your files never touch our servers, protecting your privacy 100%.
For photographs, compressing to 70–80% of the original quality is typically invisible to the naked eye. The "Balanced" preset targets this range. For graphics with flat colours (logos, screenshots), PNG compression is lossless so you won't lose any quality at all.
Yes. PNG compression is lossless — the tool optimises the PNG data structure without removing any image information. File size reductions on PNG are usually smaller (10–40%) compared to JPG, but no quality is lost.
Image size is the single biggest factor in page load time. Google's Core Web Vitals score — which directly affects search rankings — heavily penalises slow-loading images. Compressing before upload is the easiest fix.
