JPG to WebP: modernize your website's images
JPG has been the standard format for web photography for over 30 years. But in 2010, Google launched WebP with a more advanced compression algorithm capable of producing images with the same visual quality but 25-35% lighter. Today, converting JPG to WebP is one of the most recommended optimizations for improving web performance.
Google Lighthouse and PageSpeed Insights, the most widely used web audit tools, include 'Serve images in next-gen formats' as one of the main optimization points. This directly translates to better Core Web Vitals (LCP), better search engine rankings, and faster load times for users on slow connections or mobile devices.
JPG to WebP conversion on Convertir.ai happens entirely in your browser — no servers process your images. This is especially relevant if you convert watermarked or copyrighted product images, as your original files are never transmitted to third parties at any point.
