: Mod_pagespeed not compressing images mod_pagespeed is not compressing images on my homepage. My current config has: AddOutputFilterByType MOD_PAGESPEED_OUTPUT_FILTER text/html What is the usual setting

@Murray432

It turns out the because the images weren't cacheable due to some headers pagespeed would not process the images. Make sure the images are cacheable.

Your resources (images, css, javascript) aren't cacheable. If
PageSpeed sees cache-control headers such as nocache or private it
will not rewrite the resources.
