Supported Web Hosts

Most image optimization plugins require an API key or license key for compression. EWWW IO is different, and the free version requires no external service, no strings attached. However, the free compression requires certain PHP functions and more resources than some web hosts permit. To that end, I have compiled a list of hosts that I have tested, or those which have been reported by users and/or the web hosts themselves.

In general, these lists only apply to shared hosting services, although some of these are a step up (managed WordPress hosting). If the providers below have VPS or dedicated server options, those will likely work just fine. If you have any contributions or corrections to these lists,  please let me know.

Webhosts where things work (mostly) out of the box:

Webhosts where you must use the "Cloud" fork of EWWW IO at  https://wordpress.org/plugins/ewww-image-optimizer-cloud/

  • Flywheel
  • Kinsta
  • WP Engine

Webhosts where the plugin will only work in cloud mode or only some tools are installed locally:

  • Gandi
  • Hostwinds
  • ipage (JPG only)
  • ipower
  • one.com – may not even work in cloud mode

With the exception of one.com, EWWW IO will work on every and any webhost using an  API key
