Free Image Compressor Online

Image Compressor reduces the file size of photos and graphics so they load faster on the web. It works entirely in your browser by drawing the image onto a canvas and exporting it at a lower quality setting. JPEG images are compressed by reducing the quality level (1-100), which discards subtle color information. PNG compression here converts to JPEG to achieve size reduction, since PNG is inherently lossless.

The image is decoded and drawn onto an HTML Canvas element. For JPEG output, the canvas is exported using toBlob() with the chosen quality level (0.0 to 1.0). Lower quality = smaller file. The tool shows the original and compressed file sizes so you can see the exact savings achieved.
