About this image compressor
Drop in an image and control compression with the quality slider (10–95); output as JPEG, WebP, or keep the original format. After processing you get the original size, the compressed size, a compression badge such as -62%, and a preview thumbnail before downloading. PNG is a lossless format with no quality parameter — to shrink PNG files noticeably, switch the output to WebP or JPEG.
Compression re-encodes the image through Canvas using the browser's native encoders, entirely on your device — nothing is uploaded. Try several quality levels on the same picture to find the best trade-off between size and clarity.
