Optimizes but does not changes file extensions

    Seems like it optimized all the images well, especially heavy PNGs, one of them for example went from 1000KB (almost 1MB) to 68KB. However, it stayed as a PNG, and it didn’t change to WEBP.

    Browsers and Google will not still think it’s a PNG file. Ideally it should convert & replace the path in posts and pages to the new WEBP extension.

    Hello @uworlddav,

    Thanks for your opinion.

    Let me explain this to you. If the URLs were changed it would be a big problem for the cache. This means that a page once saved in the cache would always load WebP files – instead of deciding whether to load WebP for a given browser or not.

    Browsers do not consider the file extension in the URL. Many image URLs do not even have a .jpg or .png ending. When an image is loaded, the Content-Type header is also sent. It is this header that is important to the browser. By default, for .jpg files it will be “Content-Type: image/jpeg”. By redirecting files to the WebP format, my plugin changes this type to a new one – “Content-Type: image/webp”.

    Here you can compare how it looks in Dev Tools before using the plugin and after converting the images to AVIF format:

    Hope you now understand how it works and will be able to change your opinion. I’ll be very grateful for that as I really made sure the plugin was working properly.

    Best,
    Mateusz
