WebP Convert is able to convert images using multiple methods. The plugin uses the WebP Convert library to convert images to webp. With little effort, WordPress admins can have their site serving autogenerated webp images to browsers that supports it, while still serving jpeg and png files to browsers that does not support webp. What a waste of bandwidth! This plugin was created to help remedy that situation. Yet, on most websites, they are served jpeg images, which are typically double the size of webp images for a given quality. Anyhow, I opened a GitHub issue about it.More than 9 out of 10 users are using a browser that is able to display webp images.

The CDN will usually exempt "non-browser" tools from the webpification feature. Other than installing a "User Agent spoofer" extension or trying a different browser, you could also copy the URL and use the curl or wget tools through Terminal to download it (macOS should have at least one of them built-in). The URL remains the same, but the response's Content-Type header indicates the new format. The CDN's job is to host these files and reduce load on the website's real servers, but many CDNs provide various optimization features to save bandwidth for clients as well – this often includes re-compressing images, minifying JS/CSS files, and so on.Īkamai looks at the HTTP request's User-Agent header to guess what the best format supported by your browser would be (although, oddly, it ignores the Accept header) and automatically converts the image to WebP whenever it wants to. The original image uploaded to the website was an JPEG file however, it is served to you through a "content delivery network" (Akamai in this case). html in their URLs anymore even though they serve HTML-based webpages.)
