Using WebP Images

Convert your JPG / PNG images into WebP and display them on your web pages (without any browser compatibility issues).

Converting Images from JPG / PNG format to WebP Format

One or more existing JPG / PNG images can be converted into WebP format using Google's WebP converter tool:

You can change the quality parameter (-q) value to higher (upto 100, for better quality) or lower (upto 0, for lower quality). The default is 75 if the -q parameter is not specified. You can also batch convert a large number of files by writing a small batch script or a shell script.

Displaying WebP Images (without Browser Compatibility Issues)

You can use <picture> tag to display WebP images with a fallback to display JPG / PNG image on browsers that do not support WebP images:

  <source srcset='MyImg.webp' type="image/webp">
  <source srcset='MyImg.jpg' type="image/jpg">
  <img src="MyImg.jpg" alt="Your Alt Text Here" title="Your Title Text Here" />

The 'type' attribute value in the code-snippet above allows the browser to pick the right image format. Also, the <img src="..." /> ensures that the JPG image is loaded for browsers that do not support <picture> tag. Over-all, the browsers that support WebP image format will load and display WebP image while the rest would load and display the image in fallback JPG format.
