WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Essentially reduced file size without perceptible drop in quality. That in turn makes for a faster website.
Sites with large quantities of images and larger image sizes benefit dramatically. Opencart is no exception. Image quality can be imperative of sites such as photography, considerable care is taken to make their images look their best. Heavy compression can look very ugly. So it’s always a trade-off between file size and image quality. And it’s precisely at the intersection of those two things that the WebP format is targeted.
WebP typically achieves an average of 30% more compression than jpg / png images, without loss of image quality. The WebP format essentially aims at creating smaller, better looking images that can help make the web faster and in the future reduce your data storage.
Web was developed in 2010, its newly increased popularity is a result of its new owners Google. Google know SEO better than anyone else and it would be naive to think that they do not promote their own software, besides it is in their interest to so.
The biggest drawback of WebP is compatibility with browsers. Whilst it is widely supported on modern browsers like Google Chrome, Firefox, Edge and the Opera browser all support WebP, not all the versions. This has lead to various techniques in supporting both. The most simplest of which can have the opposite effect, retrieving both jpg/png and WebP and serving the WebP where supported. The drawback to this is whilst you will get good lighthouse reports for now by using their software, you will not achieve the desired goal of reducing your loading times.
