pingo — fast web image optimizer

download pingo for free


  • automatic image compression — pingo could try to detect image specifications and do automatic image compression for web. it supports many near-lossless transformations like lossy filtering, color quantization or palettization
  • web optimizer — pingo supports many formats: PNG optimizer, JPG optimizer with chroma controls, an alternative WebP optimizer or its own WebP near-lossless (both different from the lib), lossless/lossy APNG optimizer, and could convert PNG to SVGZ
  • fast and strong image optimizer — it does highly optimized compression/speed ratio, targeting better image transformations instead of more iterations. you could see some comparison with other PNG tools
  • image transformations — it could do some image manipulation like auto-rotation of JPG, CMYK JPG auto-conversion to RGB, PNG conversion to sRGB, removing PNG transparency, image to grayscale, JPG resizing, image details enhancement
  • remove all private data — pingo could remove all private data from JPG or PNG chunks which does not affect how the image is rendered. this could be done during optimization process or without processing image data
