Support » Plugin: EWWW Image Optimizer » WebP + WP Offload (S3 + Cloudfront)

  • Resolved Will Stocks



    I have just setup and bulk converted all of my images to .webp’s (I can see them all in my S3 bucket).
    I am using WP Offload to upload media to S3 and I’m using Cloudfront as the CDN to serve the images. I also use lazysizes data-srcset + LQIP.

    However, all of my images are still being served as .jpeg/.jpg/.png – none of them are being served as .webp.

    I followed the instructions on this page:

    My settings for WebP are as follows:
    webp conversion: on
    forced webp: on
    webp paths:
    alt webp rewriting: on

    Is there any way I can handle the appending of the .webp extension in PHP as opposed to relying on client-side JS? I appreciate this has some incompatibility issues with older browsers/Safari, but I’m OK with that at the moment.

    I have noticed that only my sidebar ads are being converted… but they are already .webp so are currently breaking (I can fix that myself)

    The page I need help with: [log in to see the link]

    The GitHub version, even though you install manually, has the same plugin “slug”, so it will get updates just as if you had installed it from Thanks for confirming the fixes, will follow up on the other issues Monday.
