JPG has been the standard image format for websites for over two decades. It is reliable, widely supported, and works everywhere. But in 2026, there is a better option for web images: WebP. Developed by Google, WebP delivers significantly smaller file sizes without sacrificing visual quality — and that directly translates to faster websites, better Core Web Vitals scores, and higher Google rankings. Converting JPG to WebP is one of the simplest performance improvements any website owner can make. Transfonic's free JPG to WebP converter makes it instant — no software, no account required.
