About Image Compression

Image compression reduces file size by re-encoding the image at a lower quality level. This tool uses the Canvas API to process images entirely in your browser. No files are uploaded to any server. JPEG and WebP formats support lossy compression with adjustable quality, while PNG uses lossless compression. Lower quality values produce smaller files but may introduce visible artifacts. For most web use cases, a quality of 70 to 85 provides a good balance between file size and visual quality.
