Nowadays, webp is an oft used image format preferred by modern applications that offer better-looking image compared to the popular format like JPEG, PNG or GIF. Along with being better looking, webp images are considerably smaller and make your website faster. The problem with WordPress is that it doesn’t support webp image natively. This is where this plugin comes in; with this plugin, you can enable webp support in any WordPress site regardless of theme.

On WordPress 6.4.2 works like a charm.
WebP is growing in popularity so I am always in the lookout to use modern standard and formats. I was disheartened to see that there’s no way to add webp in my WordPress, unless i cam across this plugin.
This works exactly as advertised, it’s seamless and hassle free, there’s no overhead. Pleasantly surprised to discover such a nifty plugin, I hope this gets continuous development.
