About the jpg to webp
WebP is the modern web image format. At the same visual quality it is roughly 30% smaller than JPEG, which means faster page loads and better Core Web Vitals. Every browser has supported it since 2020, so for a website there is almost no reason to serve JPEG anymore. The main time to avoid WebP is when your destination does not accept it, some older CMSes, email clients, or print services. For the web, this conversion is close to free quality-wise and a real bandwidth win. Renza converts in your browser with a quality slider, no upload, no signup, no watermark.
