Methodology
Large images were first encoded with Mozjpeg at q85 filesizes. Big is 125% of Large. Medium is 60% of Large. Small is 60% of Medium. Tiny is 60% of Small. Everything else was matched to +/- 5% filesize.
All the pictures have been compressed from RGB PNGs.
Formats
This study compares 6 differents encoders:
The Python scripts used to generate the compressed images are available on the GIT repository. The configuration file containing the codec settings is recipes.json.
