pingo optimizer
pingo, a fast image optimizer
pingo is an experimental, fast Web PNG/JPG optimizer with visually lossless or lossy compression. it performs image reductions over iterations with a recursive multi-processing system
Version:
0.91b — ZIP, Windows XP/7/8/10 — Free — manual — (32-bit version)
pingo usage
installer
- install pingo
- right click on files/folders
- Send to > Optimize for Web (pingo)
installed version can be used from Path — see how it works. alternatively, you can download 32-bit version
do backup before using pingo

usage
important
always do backup before using pingo. try on test files/folders especially made for this. understand that this tool is processing all files in subfolders. it could convert/reduce the visual quality of your files and overwrite them without any backup or warning
see the manual before using pingo
