They were created to replace older&nbsp;formats such as&nbsp;JPEG and PNG, which are heavier and less efficient for the web.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/imagify.io\/documentation\/enable-webp-images-works\/\" target=\"_blank\" rel=\"noreferrer noopener\">WebP<\/a>&nbsp;is an image format developed by Google that&nbsp;delivers superior compression for web images while&nbsp;maintaining&nbsp;high&nbsp;visual quality.&nbsp;WebP&nbsp;was introduced by Google in 2010 with a clear goal:&nbsp;to&nbsp;make websites faster by reducing image file sizes without sacrificing quality.&nbsp;<\/li>\n\n\n\n<li><a href=\"https:\/\/imagify.io\/documentation\/how-avif-works-and-how-it-can-be-enabled\/\" target=\"_blank\" rel=\"noreferrer noopener\">AVIF<\/a>&nbsp;is&nbsp;a newer image format developed by the Alliance for Open Media (AOM) that improves compression efficiency, particularly for high-resolution images.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How&nbsp;WebP&nbsp;and AVIF Compress Images Better Than JPEG and PNG&nbsp;<\/h2>\n\n\n\n<p>JPEG and PNG compression methods are limited. JPEG uses older lossy compression that removes data&nbsp;less efficiently, while PNG uses lossless compression that preserves all image data, resulting in larger file sizes.&nbsp;<\/p>\n\n\n\n<p>WebP&nbsp;and AVIF use modern compression algorithms that analyze images more&nbsp;cleverly:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>They remove redundant and invisible data&nbsp;that&nbsp;the human eye cannot perceive.&nbsp;<\/li>\n\n\n\n<li>They compress colors, textures, and gradients more efficiently.&nbsp;<\/li>\n\n\n\n<li>They store image data in smaller, more optimized blocks.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Key Differences Between JPEG\/PNG and&nbsp;WebP\/AVIF&nbsp;&nbsp;<\/h3>\n\n\n\n<p>JPEG and PNG have been the standard image formats for years, but they are no longer&nbsp;optimized&nbsp;for modern web performance.&nbsp;Here\u2019s&nbsp;a&nbsp;breakdown&nbsp;of the key differences between JPEG\/PNG and

class=\"wp-block-heading\">FAQs: AVIF vs&nbsp;WebP&nbsp;&nbsp;<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Do&nbsp;WebP&nbsp;and AVIF improve Google rankings?&nbsp;<\/h3>\n\n\n\n<p>WebP&nbsp;and AVIF do not directly improve Google rankings, but they indirectly support SEO by improving page load speed and Core Web Vitals. These next-gen formats serve much smaller images, resulting in lighter pages and faster load times. Google rewards faster websites in its algorithm.&nbsp;&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Which format is better for SEO:&nbsp;WebP&nbsp;or AVIF?&nbsp;<\/h3>\n\n\n\n<p>For SEO, AVIF is&nbsp;generally better&nbsp;because it offers a higher compression ratio than&nbsp;WebP. This means even smaller file sizes and faster page load times. Faster pages improve Core Web Vitals, which supports better visibility in search results.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Should I convert all images on my website to&nbsp;WebP&nbsp;or AVIF?&nbsp;<\/h3>\n\n\n\n<p>AVIF offers better compression than&nbsp;WebP, but browser support is not 100%. For example, some browsers, such as QQ Browser, still do not fully support AVIF. If your audience includes regions where these browsers are common,&nbsp;it\u2019s&nbsp;best to use a fallback strategy, serving AVIF first and&nbsp;WebP&nbsp;as a backup.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does Google prefer websites that use next-gen image formats?&nbsp;<\/h3>\n\n\n\n<p>Yes. Google actively recommends converting images to next-generation formats such as&nbsp;WebP&nbsp;and AVIF using tools like&nbsp;PageSpeed&nbsp;Insights. Google also recommends compressing images and serving them at the correct size.&nbsp;All of&nbsp;these techniques improve Core Web Vitals and overall page experience.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do&nbsp;WebP&nbsp;and AVIF impact Core Web Vitals?&nbsp;<\/h3>\n\n\n\n<p>WebP&nbsp;and AVIF reduce image file sizes, which helps pages load faster. This has a direct positive impact on Largest&nbsp;Contentful&nbsp;Paint (LCP), one of the most important Core Web Vitals metrics. Faster image delivery also improves overall visual stability (CLS) and perceived speed.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is AVIF supported on all browsers?&nbsp;<\/h3>\n\n\n\n<p>Almost. All major modern browsers, including Chrome, Firefox, Safari, and Edge, support AVIF. Only a few niche browsers, such as Opera Mini and QQ Browser, lack full support. AVIF is safe to use with a fallback to&nbsp;WebP&nbsp;if you really want to be on the safe side.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What\u2019s&nbsp;the easiest way to convert images to&nbsp;WebP&nbsp;or AVIF?&nbsp;<\/h3>\n\n\n\n<p>The easiest way to convert images to&nbsp;WebP&nbsp;or AVIF is to use&nbsp;Imagify, which lets you bulk-convert your entire media library to&nbsp;WebP&nbsp;or AVIF with one click. It also applies&nbsp;Smart&nbsp;compression automatically. If you&nbsp;don\u2019t&nbsp;use WordPress, online tools like&nbsp;Convertio&nbsp;are a simple alternative for one-off conversions.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Wrapping Up&nbsp;&nbsp;<\/h2>\n\n\n\n<p>Traditional image formats like JPEG and PNG were created decades ago, long before modern performance requirements and mobile browsing. In contrast, next-gen image formats such as&nbsp;WebP&nbsp;and AVIF are designed&nbsp;to reduce file size while preserving visual quality, helping websites load faster and perform better in SEO.&nbsp;<\/p>\n\n\n\n<p>Looking for the best&nbsp;WebP&nbsp;for WordPress solution or a reliable AVIF for WordPress converter plugin?&nbsp;<a href=\"http:\/\/imagify.io\/pricing\/\" target=\"_blank\" rel=\"noreferrer noopener\">Imagify<\/a>&nbsp;is the clear winner.&nbsp;It&nbsp;converts&nbsp;images to&nbsp;WebP&nbsp;and AVIF&nbsp;in one click&nbsp;while improving Core Web Vitals.&nbsp;<a href=\"https:\/\/imagify.io\/pricing\/\" target=\"_blank\" rel=\"noreferrer noopener\">Get started for free<\/a>&nbsp;and instantly reduce image size while speeding up your site!&nbsp;<\/p>\n\n\n\n\n<a href=\"https:\/\/imagify.io\/optimizer\/\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter bottom-blog-post-cta\" src=\"https:\/\/imagify.io\/blog\/wp-content\/themes\/imagify\/assets\/img\/gwic-1.png\" alt=\"Imagify, decrease the size of your images, increase the speed of your website: try it for free\" width=\"690\" height=\"190\"><\/a>","protected":false},"excerpt":{"rendered":"<p>Learn how WebP and AVIF impact SEO and Core Web Vitals, which format boosts site speed most, and the best WordPress tools tested for image compression.<\/p>\n","protected":false},"author":8,"featured_media":2976,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[],"class_list":["post-2955","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-image-optimization"],"_links":{"self":[{"href":"https:\/\/imagify.io\/blog\/wp-json\/wp\/v2\/posts\/2955","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/imagify.io\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/imagify.io\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/imagify.io\/blog\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/imagify.io\/blog\/wp-json\/wp\/v2\/comments?post=2955"}],"version-history":[{"count":6,"href":"https:\/\/imagify.io\/blog\/wp-json\/wp\/v2\/posts\/2955\/revisions"}],"predecessor-version":[{"id":2977,"href":"https:\/\/imagify.io\/blog\/wp-json\/wp\/v2\/posts\/2955\/revisions\/2977"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/imagify.io\/blog\/wp-json\/wp\/v2\/media\/2976"}],"wp:attachment":[{"href":"https:\/\/imagify.io\/blog\/wp-json\/wp\/v2\/media?parent=2955"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/imagify.io\/blog\/wp-json\/wp\/v2\/categories?post=2955"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/imagify.io\/blog\/wp-json\/wp\/v2\/tags?post=2955"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
