Using next-gen image formats improves:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>LCP (Largest Contentful Paint)<\/li>\n\n\n\n<li>FCP (First Contentful Paint)<\/li>\n\n\n\n<li>Overall user experience signals that impact search rankings.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">\u2699\ufe0f 5. <strong>Support &amp; fallbacks are easy now<\/strong><\/h3>\n\n\n\n<p>Most modern browsers support WebP and AVIF. You can use WordPress plugins, various tools, or CDNs to automatically serve the right format to each visitor.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What are next-gen image formats and why do they matter?<\/h2>\n\n\n\n<p>Next-gen image formats are modern image compression standards designed to outperform traditional formats like JPEG and PNG in both quality and file size. <\/p>\n\n\n\n<p>The two leading formats in this category are WebP and AVIF.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>WebP<\/strong>, developed by Google, supports both lossy and lossless compression, transparency, and animation. It typically reduces file size by up to 35% compared to JPEG while maintaining comparable visual quality.<\/li>\n\n\n\n<li><strong>AVIF<\/strong> is even more advanced. It uses the AV1 video codec and achieves significantly higher compression rates than both JPEG and WebP, often cutting file sizes by 50% or more, especially for high-resolution images.<\/li>\n<\/ul>\n\n\n\n<p>But this isn&#8217;t just about smaller images. It\u2019s about faster websites, reduced bandwidth consumption, and a direct boost to user experience and search engine rankings. <\/p>\n\n\n\n<p>With Google placing increasing emphasis on performance metrics like Core Web Vitals, <strong>using formats like WebP and AVIF becomes mandatory<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How next-Gen image formats impact website load speed<\/h2>\n\n\n\n<p>Images typically account for around 50% of a webpage\u2019s total size. That makes image optimization one of the most effective ways to reduce load times. Faster sites load more smoothly, retain visitors longer, and perform better in search engine results.<\/p>\n\n\n\n<p>When comparing <a href=\"https:\/\/shortpixel.com\/blog\/avif-vs-webp\/\" data-type=\"link\" data-id=\"https:\/\/shortpixel.com\/blog\/avif-vs-webp\/\">WebP vs AVIF<\/a> for websites, AVIF offers better compression but has slightly slower encoding times and less widespread browser support. WebP, on the other hand, enjoys broader compatibility and faster processing, making it a practical choice for most websites today.<\/p>\n\n\n\n<p>Switching to either format can have a dramatic impact on metrics like:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>First Contentful Paint (FCP)<\/li>\n\n\n\n<li>Largest Contentful Paint (LCP)<\/li>\n\n\n\n<li>Time to Interactive (TTI)<\/li>\n<\/ul>\n\n\n\n<p>All of which contribute to SEO and user satisfaction. In Google\u2019s eyes, a faster-loading page is a better page.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Converting images to next-gen formats<\/h2>\n\n\n\n<p>The process of converting images doesn\u2019t have to be complicated. <\/p>\n\n\n\n<p>Several tools exist to help automate the transformation of your existing media library:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/shortpixel.com\/online-image-compression\" data-type=\"link\" data-id=\"https:\/\/shortpixel.com\/online-image-compression\"><strong>ShortPixel<\/strong><\/a> &#8211; Free browser-based image compressor that can generate WebP and AVIF files.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/squoosh.app\/\" data-type=\"link\" data-id=\"https:\/\/squoosh.app\/\" target=\"_blank\" rel=\"noopener\">Squoosh<\/a><\/strong> &#8211; Free browser-based tool by Google.<\/li>\n\n\n\n<li><strong>cwebp\/avifenc<\/strong> \u2013 command-line utilities for batch conversion.<\/li>\n\n\n\n<li><strong>ImageMagick<\/strong> \u2013 a command-line tool that supports both WebP and AVIF.<\/li>\n<\/ul>\n\n\n\n<p>For developers managing larger sites, integrating conversion into your CI\/CD pipeline ensures every new asset is optimized before hitting production.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Implementing next-gen image formats on your website<\/h2>\n\n\n\n<p>Once your images are converted, you\u2019ll need to serve them properly to ensure compatibility with all browsers.
