Are you looking for a plugin to convert your images to WebP? If you deal with many images and aim to reduce and optimize their file size or convert them to WebP, this is a great step.
WebP is a next-generation web format developed by Google that significantly reduces the file size of JPEG, GIF, and PNG images.
By using the WebP format instead of JPEG, GIF, and PNG, your images will be better optimized, improving your site speed and performance score on PageSpeed Insights.
Although you can manually convert your images to WebP using Photoshop or Sketch, WordPress plugins are much more convenient and save a lot of time.
To help you choose, Mangcoding recommends essential features to look for when selecting a WebP plugin for WordPress:
1. Bulk Conversion Feature
If you have hundreds of images in your WordPress library, you need a single button to convert them all to WebP in one click, saving a lot of time.
- When a browser loads an image, the plugin should check whether the browser supports the WebP format. For a better user experience, you should serve WebP images only to browsers that support this format and fallback to JPEG or PNG for those that don’t.
- Be sure to check your file size before and after converting to WebP—you should save about 25% to 40% of the image file size.
2. Image Conversion via Remote Server
Check whether the plugin developer uses their own server for optimization and conversion so that it does not affect your hosting resources.
Now that you know what to look for in a WebP converter plugin, Mangcoding will discuss the 4 best WebP plugins for WordPress below.
