about pingo
  • it is speed/space based — it will not provide maximum compression
  • pingo could adjust quality whatever the lossy option
  • pingo has quality limitations because lower will be probably bad
bugs report
  • i am interested to fix bugs in current version (not older)
  • be sure you are using the latest pingo
  • please do report with all informations (version, options, OS, files, etc.)
  • any feedback is welcome even to say that it is working
  • sorry but i do not have time to help about how tools work — do trials yourself
  • for maximum performance, you should not use in a file-per-file process
  • it could be less efficient to combine pingo with other tools
  • tools seem to work on Linux (using wine)
  • i do not provide any other tool
  • i do not provide older/other versions
  • there is no roadmap — no previsions — no dates
  • all tools are experiments and maybe sub-optimized
other techs
  • Guetzli is not used in pingo — see why
  • Lepton is a JPG packer, not and optimizer — see PackJPG
