About Image Compression
This tool uses the browser's built-in Canvas API to re-encode images at a lower quality. JPEG and WebP support lossy compression with a quality slider. PNG uses lossless compression — use JPEG or WebP for significant size reduction.
Note: WebP encoding requires Chrome, Edge, or Firefox. PNG compression via Canvas re-encodes at full quality with no quality slider effect — convert to JPEG or WebP for smaller file sizes.
