How do you convert the files to webp? Do you use a plugin for this, and if so, which one? Or do you use the options offered by your hosting provider? In my experience, webp files can sometimes be larger than the original images. This is due to the different structure of the format, but it often also depends on hosting factors and which PHP libraries are used (because ultimately it is PHP that generates the files, not WordPress).
I have used these two software to convert Modern Image Formats and Converter for Media before, but now they are both disabled. But after uploading jpg, it is still directly converted to webp, which is larger than jpg format. It optimizes the tag. Now I don’t know which software is doing the conversion.
As mentioned above: PHP with a compatible library in your hosting, initiated by WordPress itself. Check which PHP version you are using and set it to 8.3 if necessary. Or contact your host’s support team for assistance.
Hi, I believe I have seen this before. Sometimes WebP can be larger than JPG, especially if the original file is already optimized. This typically depends on the quality settings or the conversion method your server uses. I’d recommend lowering the WebP quality setting, resizing images before upload, and clearing the cache after changes. That usually resolves the issue and reduces the upload size. If it still doesn’t work, better reach out to the support team.
