What is WebP and why is it used?

Google created the WebP image file format to take the place of the JPEG, PNG, and GIF file formats. It enables animation, alpha transparency, and both lossy and lossless compression. The most widely used next-generation image format is WebP. 90% of modern web browsers support this Google-developed open-source format. It’s become a popular topic lately as it pulled ahead in the next-gen image format wars: as of this writing, it’s supported on Chrome, Microsoft Edge, Firefox, Opera, and most recently Safari. Adopting WebP at this time is a sure bet. The user experience for practically all of your website visitors will be improved if you modify your WordPress or custom-built site to support it, it's SEO recommended to use WebP in your designs which makes your website lighter, run faster, and smoother, which translates to higher search engine rankings and a better experience for visitors. Despite all the recent hoopla, WebP pronounced "weppy" is a somewhat ancient technology. Since its initial announcement in 2010, it has been updated and improved to reach its present condition.
