Issue with WebP Image Serving Not Working

Hello LiteSpeed Cache Support Team,

I am experiencing issues with WebP image serving on my WordPress website. Despite following the setup process and properly configuring the plugin, WebP images are still not being served as expected.

So, here’s the description of the things i’ve checked and tried:
- WebP files are being generated by the LiteSpeed Cache plugin and are present in the /wp-content/uploads/ folder.
- The plugin settings have been configured as follows:
  - “Next-Gen Image Format” is set to WebP (ON).
  - “WebP/AVIF for Extra srcset” is enabled.
  - “Use Optimized Files” option has been selected.
- I have used the Soft Reset Optimization Counter and re-scanned & optimized images successfully.
- Cache has been purged multiple times.
- The .htaccess file has been updated to include the WebP serving rules. https://prnt.sc/o3qp07GwIl1-
Testing Results:
- Testing with Chrome DevTools shows that images are being served as image/jpeg or image/png, not as image/webp.
- Right-clicking images and opening them in a new tab also shows them as .jpg or .png.
- The server supports WebP, because i’ve manually uploaded WebP files before.
Additional Information:
- I am using Divi Child Theme for the website.
- The server uses LiteSpeed and .htaccess rules are allowed.
Could you please assist me in resolving this issue? Are there any additional configurations I should apply, or could there be a problem with the way the plugin is handling WebP delivery?

Thank you in advance for your assistance!

Best regards,
Antonyia

I did a purge all, but it’s still the same. I tested the website through incognito and there i see them in webp. So it’s serving the images in webp only for first time visits. When i Empty Cache and Hard Reload the page it’s serving the images in jpeg and png again. Is that how it’s supposed to be?

no , that must be something wrong

please try grab the log

go to toolbox -> debug setting -> set debug to ON , debug level to advance , add test into debug include URI

then go to toolbox -> log view -> clean up existing logs if any.

open the page as https://yourdomain.com/?test

go to toolbox -> log view -> copy paste the log and share it via https://pastebin.ubuntu.com/

Hello again!

Sorry for the late response! You’re right! As guest user I can see the images served as WebP in desktop view, but when I test it from mobile view, the images are served in their original type (jpeg and png). Here’s a screenshot: https://prnt.sc/ynRp7hirHdna and from pagespeed opt https://prnt.sc/NBSVp_0W5oS3

Hello!

Maybe, yes. I tried again now and the problem is gone from the diagnostics at PSI. https://pagespeed.web.dev/analysis/https-nikealtd-com/hotbhv92qu?form_factor=mobile
