Image Compressor
Upload an image to compress it — entirely in your browser, using your browser's own image encoder.
About this tool
Your image is never uploaded to a server — compression happens entirely in your browser via the Canvas API. PNG is a lossless format, so it doesn't have a quality slider the way JPEG and WebP do; choose JPEG or WebP for the largest size reductions.
