Pingo - image optimizer for web

Automatic image compression — pingo could try to detect image specifications and adjust the lossy type or quality itself. it supports many transformations like lossy filtering, color quantization, or paletted

PNG, JPG, WebP, or APNG — it should optimize or convert those formats recursively for the web. it could do some alternative lossy transform to preserve image visual perception for PNG/WebP or SVGZ and lossy compression

Fast and strong image optimizer — it does progressive and highly optimized compression / speed ratio. You can see the 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 ehancement

Remove all private data — pingo can remove all private data from JPG or PNG chunks that do not affect how the image is rendered. This could be done during the optimization process or without processing image data
