Best Convert Webp WordPress Plugins

WebP conversion plugins automatically encode JPEG and PNG uploads into the WebP format, which delivers equivalent visual quality at 25-35% smaller file sizes according to Google's research, meaningfully reducing page weight and improving Core Web Vitals scores. Rather than requiring manual re-export from image editing software, these plugins handle conversion server-side on upload or in bulk for existing media libraries, and serve WebP to supporting browsers while falling back to the original format for older clients via the HTML picture element or .htaccess rules. E-commerce stores with large product image catalogues, image-heavy blogs, and performance-focused sites use WebP conversion plugins as a high-impact, low-effort speed optimisation. WebP support now covers over 95% of global browser usage, making the format safe to adopt as a default.
