Do I need an API key along with Easy IO?

The short answer is "no", but there are reasons you might use both the Compress API and Easy IO together...

When you activate Easy IO, every image your visitors load will be going through our CDN, and will be automatically compressed.

But this is all done on copies of your images, stored on our CDN servers. Easy IO never alters the original images stored on your web server.

So, when do you use the Compress API in addition to Easy IO?

  1. If you need to save on the storage space used by your website, you can use your Compress API key and run a Bulk Optimize.
  2. If you just plain prefer to have the compressed images stored permanently on your server instead of only on our servers, then you should use the Compress API (via the bulk optimizer).
