Why Convert to WebP in 2025?
WebP has become the standard for web image optimization, offering superior compression compared to traditional formats like JPEG and PNG. As of 2025, WebP is supported by 98% of browsers globally, making it the ideal choice for modern web development.
Performance Boost
WebP images are typically 25-35% smaller than JPEGs at equivalent quality, significantly improving page load times.
SEO Advantages
Google prioritizes sites with fast-loading images in search rankings, directly impacting your visibility.
Better UX
Faster loading images improve Core Web Vitals scores and reduce bounce rates, especially on mobile.
