automatic image compression — pingo could try to detect image specifications and adjust 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 format recursively for 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 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 ehancement
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
