To use KeyCDN as your CDN when using ShortPixel Adaptive Images<\/a>, instead of ShortPixel’s CDN, follow these steps:<\/p>\n\n\n\n

    \n
  1. Create an account with KeyCDN if you have not already done so: https:\/\/www.keycdn.com<\/a><\/li>\n\n\n\n
  2. Go to Zones<\/strong> to create a new zone.<\/i><\/li>\n\n\n\n
  3. Enter the following data:\n
      \n
    1. Zone Name<\/b>: spaimg<\/code> for example, or whatever you feel it can represent this zone used to deliver your images through our plugin.<\/li>\n\n\n\n
    2. Zone Status<\/b>: active<\/li>\n\n\n\n
    3. Zone Type<\/b>: pull<\/li>\n\n\n\n
    4. Origin URL<\/b>: https:\/\/no-cdn.shortpixel.ai<\/code><\/li>\n\n\n\n
    5. Image Processing<\/b>: disabled<\/li>\n\n\n\n

    6. Expand the General settings<\/b> and look for the SSL <\/b>option. Select letsencrypt<\/strong>.<\/p>

      <\/figure><\/figure><\/li>\n<\/ol>\n<\/li>\n\n\n\n
    7. Save the new zone.<\/li>\n\n\n\n
    8. Think about a name for the subdomain you want the images to be delivered from. For example, if your domain is mywebsite.com, you could choose\u00a0img<\/code>.mywebsite.com. If img<\/code> is already used by another CNAME, think of something else, like\u00a0images<\/code>.mywebsite.com or\u00a0media<\/code>.mywebsite.com.<\/li>\n\n\n\n
    9. Go now to Zone Aliases<\/strong> and click on Add Zone Alias<\/strong>.<\/li>\n\n\n\n
    10. Enter the alias you want, which will be what you have thought of in step #5. For example, img.mywebsite.com<\/code>. Remember that\u00a0mywebsite.com<\/code> should be changed to your actual domain.<\/li>\n\n\n\n

    11. Choose the zone you created previously.<\/p>

      <\/figure><\/li>\n\n\n\n

    12. Go back to Zones<\/strong> and copy the zone URL.<\/p>

      <\/figure><\/li>\n\n\n\n

    13. In the DNS editor of your domain (ask your domain provider if you don’t know where it is), add a new\u00a0CNAME<\/strong>\u00a0record\u00a0from\u00a0img.mywebsite.com<\/code> to\u00a0the zone URL.<\/p>

      <\/figure>

      Remember that\u00a0mywebsite.com<\/code> should be changed to your actual domain.<\/p><\/li>\n\n\n\n

    14. Wait 5 minutes<\/strong>\u00a0for your domain provider to complete all technical tasks in the background.<\/li>\n\n\n\n
    15. Check with this tool<\/a> if your CNAME is propagated correctly. If not, wait 24h-48h.<\/li>\n\n\n\n
    16. Take any image URL from your website, append it to\u00a0https:\/\/img.mywebsite.com\/spai\/q_lossy+ret_wait\/<\/code> and make sure that the new URL can be accessed. Example:\n
        \n
      1. If your website is called mywebsite.com, your new CNAME is\u00a0img.mywebsite.com<\/code>, and your sample image is\u00a0https:\/\/www.mywebsite.com\/wp-content\/uploads\/2022\/04\/image.jpg<\/code>,<\/li>\n\n\n\n
      2. try to access this URL:\u00a0https:\/\/img.mywebsite.com\/spai\/q_lossy+ret_wait\/https:\/\/mywebsite.com\/wp-content\/uploads\/2022\/04\/image.jpg<\/code><\/li>\n\n\n\n
      3. Can you view it without errors? Proceed to the next step.<\/li>\n<\/ol>\n<\/li>\n\n\n\n
      4. You have done everything on KeyCDN. Now go to your WordPress website and change the API URL of ShortPixel AI.\n
          \n
        1. Go to\u00a0Settings > ShortPixel AI > Behaviour and enter\u00a0https:\/\/img.mywebsite.com\/spai<\/code> in the\u00a0API URL<\/strong>\u00a0field.<\/li>\n\n\n\n
        2. Replace\u00a0mywebsite.com<\/code> with your\u00a0actual domain<\/strong>\u00a0name.<\/li>\n\n\n\n

        3. Replace the\u00a0img<\/code> part if your subdomain is different, like configured above.<\/p>
