Use JS to Detect Help for WebP
Use Browser to simply accept headers
Modify .htaccess file in WP
Serve with HTML5

The customer’s browser will ship an “settle for” request header, indicating what picture codecs it’s going to settle for from the online server (love, Firefox).

It begins with a dot (.) that means it’s a hidden file. You received’t see it when you haven’t made hidden information seen
It doesn’t have a file extension
In case you make a mistake enhancing it, your server could severely malfunction, so solely edit it if you realize what you’re doing!

In WordPress, this file is usually used to rewrite URLs. On this case, the URL of the picture is modified and a .webp extension is added.

In Vincent Orback’s code on GitHub for instance, the .htaccess file is modified. JPEG and PNG picture URLs are modified if there’s a WebP model inside the identical folder and if the browser helps WebP. The duty of serving the precise picture, on this case, falls on the Apache net server.

4. Serve a number of sizes and codecs with HTML 5

One of many higher methods to serve WebP photos is by counting on the browser to decide on the very best picture and utilizing the HTML5 <image> aspect to speak the completely different photos which are accessible for the browser to select from. Not solely can you utilize the <image> aspect to supply completely different picture codecs, but in addition completely different sizes for cellular and retina units. Take a look at this cute instance.

Whereas the HTML of a picture will look one thing like this:

<img src=”picture.jpg” alt=”my picture” width=”100″ peak=”100″ />

The <image> aspect has much more happening:

<image>
  <supply srcset=”picture.webp” kind=”picture/webp”>
  <supply srcset=”picture.jpg” kind=”picture/jpeg”>
<img src=”picture.jpg” alt=”my picture” width=”100″ peak=”100″>
</image>
