What is JPG Compressor?
JPG Compressor reduces photo file size by re-encoding JPG images with a selected quality level. JPG compression is lossy, so lower quality settings create smaller files by discarding more detail. The tool previews the result, compares file sizes, and preserves the original image dimensions.
How does JPG Compressor work?
This tool decodes the JPG file in the browser, draws it to canvas, and exports a new JPG at the selected quality value. The width and height stay the same, but the encoder changes compression strength. Lower settings reduce bytes more aggressively and can introduce visible artifacts.
