For example, if your theme displays images with a maximum width of 800px, I recommend you enter at least 1000px for the maximum width. ShortPixel will give you directions to make sure you don’t make the values too low.
If you want to take advantage of some of ShortPixel’s more advanced (and optional) features, you can go to the Advanced tab.
ShortPixel Advanced Settings
Here, you can set up options to do things like:
Convert PNG images to JPEG
Use WebP images
Optimize Retina images
Automatically exclude certain images from being optimized
Again – these settings are entirely optional. But WebP images special marketing lead can be 25% smaller than other image types, so it’s nice to have access to these features.
