What is WebP?
WebP is a next-generation image format released by Google in 2010. In lossless mode it averages 26% smaller than PNG, and in lossy mode 25β34% smaller than JPG β all while supporting transparency and animation. Every major browser (Chrome, Firefox, Safari, Edge) supports it natively, though some legacy messengers, older email clients, and older Windows environments may still fail to open WebP files. If your goal is website speed optimization and better SEO scores, WebP should be the first format you consider.
When should I use WebP?
Of greatest value to anyone running a website, blog, or e-commerce store. Batch-converting JPG/PNG assets to WebP typically produces files 25β30% smaller at the same visual quality, with immediate improvements to page load speed and Lighthouse scores. That directly impacts Google's Core Web Vitals (LCP), a known SEO signal. The caveat: if end users need to download files and open them in other apps, JPG/PNG remains safer due to broader compatibility.
