about pingo
  • it is speed/space based — it will not provide maximum compression
  • pingo could adjust quality by itself whatever the lossy option
  • pingo has quality limitations because lower will be probably bad
  • if you want help about how pingo works — read usage
  • for maximum performance, use pingo alone and not throught a front-end/batch
  • you should not use throught single/multithreading: pingo does this by itself
  • it seem to work on Linux (using wine)
  • i do not provide any other tool than pingo
  • i do not make custom build or provide older version
  • there is no roadmap — no previsions — no dates
  • i could not guarantee that the tool works correctly
bugs report
  • i am interested to fix bugs in current version (not older)
  • be sure you are using the latest version of pingo
  • it could help if you do trials yourself — if it bugs on a file, provide it
  • please do report with all informations (version, options, OS, files, etc.)
  • here is the way to contact me
other techs
  • those techs are not used in pingo
  • Guetzli — mainly because of speed (see comparisons)
  • Lepton — which is a JPG packer, not an optimizer (see PackJPG)
