What Is Image Compression?

Image compression reduces the file size of images while preserving acceptable visual quality. This tool uses browser-native Canvas API to re-encode images at your chosen quality level, with no server upload required. Lower quality values produce smaller files but may introduce visible artifacts. WebP generally offers the best compression ratio, while PNG is lossless and best for graphics with sharp edges or transparency.
