Only some images being served as WebP?

    Hello!

    Despite not being very technical I decided to try using this plugin to serve WebP images. I am hosted with Siteground and I use Cloudflare, so I enabled the JS serving version. I then Bulk Optimized all my existing uploads.

    I am finding that on every page, some images are being served as WebP and some are not. I followed this thread https://wordpress.org/support/topic/webp-conversion-not-working/ and inspected the images as per this video https://www.youtube.com/watch?v=ywBkIhCSAJ4 to confirm that this isn’t a case of Siteground delivering images in transparent mode – it seems they just have not all converted or are not all being served.

    Do you have any idea why that might be? It seems totally random. On some pages I might have two images next to each other and one will be serving as WebP and another as a jpeg.

    Thanks for your help!

    Hi @annalou74, could you give me an example of specific images that you’re seeing as WebP and ones that are in JPG? And if that isn’t on your home page, let me know the exact URL I can check to see what might be happening.

    Also, do note that Siteground does have automatic (transparent) WebP delivery on their platform. My understanding was that it was on by default with no “off switch”, but perhaps they’ve updated that. In any case, it doesn’t work well with Cloudflare, so maybe they detect Cloudflare and turn that feature off dynamically? Or they have an “off switch” now and it’s been disabled for your site? I’d make very sure of that part, because otherwise, non-WebP browsers risk getting broken images because Cloudflare won’t vary the content unless you use their Pro solution with WebP built-in.

    Many thanks for your help

    Siteground do have a WebP option, but it is definitely disabled (and it’s not set as on as default)

    So on the homepage, only the pencil drawing of the boy (second image, below the header) is being served as WebP. The rest are still Jpegs. And on this page for example https://www.annabregmanportraits.co.uk/photos/ the photos of the two girls are WebP and the picture of the dog is still a jpeg. On this page https://www.annabregmanportraits.co.uk/feedback/ the photo is WebP and the drawing is a jpeg.

    In both those cases, it looks like the JPEG images are shown because a .webp image doesn’t exist (adding .webp to the URL gives a 404/Not Found error).
    Are all those images in your Media Library? If so, I would switch the library to “list view” and see what it shows for optimization results on the ones that were not converted vs. the others that *were* converted.

    You were right, for some reason the bulk optimizer was stopping half way through the library and I had to manually optimize the rest of them. Thanks very much for your help
