Flush cache of one image<\/h2>\n

\n\t If you are using
\n\tShortPixel Adaptive Image<\/a> or Autoptimize<\/a> (with the option to optimize images with ShortPixel) and you need to flush one of the CDN-cached images<\/strong> you can do it like this:<\/p>\n

    \n
  1. Take the URL of the image in the CDN. For example: \n
    https:\/\/cdn.shortpixel.ai\/spai\/w_605+q_lossless+ret_img+to_webp\/https:\/\/blog.shortpixel.com\/wp-content\/uploads\/2019\/06\/web-design-1-1024x734.jpg<\/pre>\n<\/li>\n
  2. Copy the URL in your browser and add f_remove+<\/code> after https:\/\/cdn.shortpixel.ai\/spai\/<\/code>, like this:<\/strong>\n
    https:\/\/cdn.shortpixel.ai\/spai\/f_remove+w_605+q_lossless+ret_img+to_webp\/https:\/\/blog.shortpixel.com\/wp-content\/uploads\/2019\/06\/web-design-1-1024x734.jpg<\/pre>\n<\/li>\n
  3. Wait 30 seconds, and then the image should be flushed from the CDN cache.<\/li>\n
  4. If you are using your own CDN<\/a> with ShortPixel Adaptive Images, the previous steps may not work and you will have to flush your own CDN’s cache <\/strong>from your CDN control panel as well.<\/li>\n<\/ol>\n
    Flush cache of all images (only ShortPixel AI)<\/h2>\n
    \n\tNote<\/strong>: if you are using Autoptimize, please follow these instructions<\/a>.<\/em><\/p>\n
    \n\t If you would like to flush the cache of
    \n\tall images<\/strong> in our CDN, then the workaround that you can use is the following, equivalent to flushing the whole CDN cache for a website:<\/p>\n
      \n
    1. Go to your WordPress dashboard<\/li>\n
    2. Go to Settings > ShortPixel AI > Behaviour<\/li>\n
    3. Look for the field API URL<\/strong>, and change https:\/\/cdn.shortpixel.ai\/spai<\/code> to https:\/\/cdn.shortpixel.ai\/spai2<\/code> like in the example below:\n
      \n\t\t\n\t<\/p>\n<\/li>\n<\/ol>\n
      \n\t Afterwards, if you want again to flush the whole cache you can change https:\/\/cdn.shortpixel.ai\/spai2<\/code> to https:\/\/cdn.shortpixel.ai\/spai3<\/code> and so on – just increase the number each time you want to flush the cache again.<\/p>\n","protected":false},"excerpt":{"rendered":"
