Am I missing something? When I read this…
Optimising the file size of your images shouldn’t mean making them grainy or blurred. Squash can maintain quality while reducing file size and saving space.
…I imagined Squash doing the work of figuring out what compression level to use. But all I can see is a quality slider like every other JPEG exporter.
Given I have to choose a single quality level for the entire batch, this doesn’t seem like ‘optimisation’ at all.
