Why Convert Images to WebP or AVIF?
Modern image formats like WebP and AVIF offer superior compression compared to traditional PNG and JPEG files. This means smaller file sizes, faster page loads, better SEO rankings, and improved user experience—especially on mobile devices.
Smaller File Sizes
Reduce image file sizes by 25-50% compared to PNG/JPEG while maintaining the same visual quality. Perfect for faster website loading times.
Faster Page Loads
Smaller images mean faster page load times, which improves Core Web Vitals, SEO rankings, and user experience. Google rewards fast websites.
Better Mobile Experience
Optimized images consume less bandwidth on mobile devices, saving users' data and improving page load speeds on slower connections.
Improved SEO
Google uses page speed as a ranking factor. Smaller, optimized images help improve your Core Web Vitals scores and search engine visibility.
