WebP is an open-source image file format developed by Google. It has better compression rate than other image formats (PNGs, and JPEGs).

Here is some base info about the WebP image format and how to integrate it for WordPress:

The WebP image format has better lossless compression (original bits of the image which will remain after the actual uncompression) than other image formats.

As a result, comparing to JPEG and PNG image file formats, the same images in WebP format will have between 25% and 34% smaller size than the older image format.

There are WordPress plugins which would allow you to easily convert your Media Library images into the WebP image format.

When a new image is uploaded to Media Library, it will be automatically converted to WebP format using Imagick or GD PHP extensions.

It also support browser check of WebP format, in case it’s supported the image will be sent in WebP format.
