Can I use a different CDN with ShortPixel Adaptive Images?

Important note: ShortPixel Adaptive Images works correctly out-of-the-box, so configuring it to work with your own CDN should only be done if you have  good technical knowledge. Please consider checking how are the credits counted if you use your own CDN.

If you want to use a different CDN than the default cdn.shortpixel.ai when using ShortPixel Adaptive Images, follow the instructions below:

  1. Edit your DNS records to add a CNAME from cdn.example.com to no-cdn.shortpixel.ai. This step might be slightly different depending on what CDN you use. Below you can see some examples, but we recommend you contact your CDN provider so they can help you set this up.
    1. On the previous URL, replace example.com with your actual domain name.
    2. If cdn.example.com is already being used on your DNS records, you can change it to whatever you want, like images.example.com or img.example.com.
  2. Make sure the new record (cdn.example.com) works as expected with an online tool like whatsmydns.net.
  3. Go to Settings > ShortPixel AI > Behaviour > API URL and enter the following URL: https://cdn.example.com/spai
    1. Replace example.com with your actual domain name.
    2. Replace the cdn part if your subdomain is different, like configured above.
    3. Please note that if you're not using Cloudflare as CDN, then your CDN should be able to handle the SSL certificate so you can have the API URL with https. If they cannot handle this, a certificate error will occur and your API URL should start with http instead of https.
