As I am trying to get most out of the images it does not make much sense to me to work without a visual control mechanism as every image needs different parameters to get most out of it. So, no, at the moment there is no batch tool available.
A WordPress plugin is on my todo list for a loooong time but unfortunately I can't say when it will see the light of day.
No, sorry.
That's why I often still go for JPG instead of the newer image formats. Progressive decoding is just so important. Really excited to see the acceptance of JpegXL! twitter.com/cloudinary/sta…
