Lossless compression could be optimized for jpg files

pdewouters opened this issue · comments

Using this tool https://yellowlab.tools - to scan a web page with images served by tachyon, it recommended optimisations to file size. These are pretty significant ( total of 1.6MB ).

To test this assumption, I downloaded an image from the page, and optimised it with the ImageOptim app, using lossless compression with default settings. Note that there is an "insane" setting...
The results showed an extra gain of 28.3%
