Uploaded files do not convert to WebP

@rjrjrjrj Hi there, thanks for getting in touch!

Can you confirm that your server supports WebP? The best way to tell is by going to Tools > Site Health > Status. If you see a recommended improvement that says “Your site does not support WebP,” the WebP generation for new JPEG uploads will not work.

If you do not see that message or you see a message that says “Your site supports WebP” under Passed Tests, there may be something else going on. Can you please share your Site Health information here?

Your site supports WebP Performance

The WebP image format produces images that are usually smaller in size than JPEG images, which can reduce page load time and consume less bandwidth.

@rjrjrjrj Thank you! Can you please copy and paste your full Site Heath information in a reply on this topic? The instructions are in this screenshot.

@rjrjrjrj Thanks for sharing! Based on your settings, WebP is supported and should be working. Can you please try the following steps and let me know what happens?

1. Make a new post.
2. Add a new JPEG file to your media library.
3. Insert the image into your post’s content.
4. Make your post visible to the public.
5. Go to the post URL and inspect to view the post markup and verify if a WebP file is being used for the image.

If you’re still not seeing a WebP image, it’s likely that there’s a conflict somewhere between the Performance Lab plugin and either your theme or another plugin. To test this, you can install the Health Check & Troubleshooting plugin to safely activate only Performance Lab and switch to a default theme. If WebP conversion works in Troubleshooting Mode, it’s likely that there is a conflict, and you can reactivate your plugins and theme one-by-one to try to identify what is conflicting. More details on how to use that plugin are available here.

We cannot afford that effort and will have to pre-convert images to webp instead.

@rjrjrjrj Understood, thanks for the update. I’ll mark this topic as resolved for now, but if you have any other questions, feel free to reply here. Thank you!

In case you are still looking for the answers: I faced the same issue 5 months back while working on my client’s website, which was related to?sublimation printers?and involved a lot of images and image sizes. I found a WordPress plugin that worked wonders for me: “Ewww image optimizer” by Exactly www and “web express” by Bjorn Rosell. Give these a try, and let me know how these worked for you.
