Explained in more detail<\/h2>\n<p>When it comes to saving images for use on the web, there are <a href=\"https:\/\/themeisle.com\/blog\/best-image-format\/\">a number of file types<\/a> you can use. The three most common options are PNG, JPEG (or JPG), and GIF. While these formats are popular, each has its own unique pros and cons:<\/p>\n<ul>\n<li><strong>JPEGs<\/strong> can display highly-detailed images with lots of colors, making them perfect for photographs. At the same time, the files are often very large and don\u2019t always hold up well under compression.<\/li>\n<li><strong>PNGs<\/strong> are ideal for images without a lot of data involved, <a href=\"https:\/\/themeisle.com\/logo-maker\/\">such as logos<\/a>&nbsp;or <a href=\"https:\/\/themeisle.com\/blog\/how-to-screenshot-on-computer\/\">interface screenshots<\/a>. They\u2019re excellent at retaining quality <a href=\"https:\/\/themeisle.com\/blog\/wordpress-image-optimizer-plugins-compared\/\">when compressed<\/a>, and support transparency, but don&#8217;t work well for photographs.<\/li>\n<li><strong>GIFs<\/strong> are excellent for animations, but not great for saving static images.<\/li>\n<\/ul>\n<p>WebP images are an image <a href=\"https:\/\/developers.google.com\/speed\/webp\/\" rel=\"noopener\" target=\"_blank\">format from Google<\/a> designed to let you display images on the web at a similar quality level to existing image formats, but with a smaller file size.<\/p>\n<p>To achieve this, WebP provides both <a href=\"https:\/\/whatis.techtarget.com\/definition\/lossless-and-lossy-compression\" target=\"_blank\" rel=\"noopener\">\u2018lossy\u2019 and \u2018lossless\u2019 compression<\/a> options. The latter preserves more data, while the former makes the resulting file sizes even smaller.<\/p>\n<p>According to <a href=\"https:\/\/developers.google.com\/speed\/webp\/docs\/webp_study\" target=\"_blank\" rel=\"noopener\">Google&#8217;s data<\/a>, WebP images are <em>on average<\/em>:<\/p>\n<ul>\n<li><strong>25-34% smaller<\/strong> in size than comparable JPEG images.<\/li>\n<li><strong>26% smaller<\/strong> in size compared to PNGs.<\/li>\n<\/ul>\n<p><img data-opt-id=407024337  fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter size-full wp-image-20718\" style=\"-webkit-box-shadow: 0px 0px 8px 2px rgba(0,0,0,0.5); -moz-box-shadow: 0px 0px 8px 2px rgba(0,0,0,0.5); box-shadow: 0px 0px 8px 2px rgba(0,0,0,0.5);\" src=\"https:\/\/mllj2j8xvfl0.i.optimole.com\/cb:c5QE.37290\/w:auto\/h:auto\/q:mauto\/f:best\/https:\/\/themeisle.com\/blog\/wp-content\/uploads\/2018\/11\/webp.png\" alt=\"what is webp?\" width=\"1105\" height=\"443\" srcset=\"https:\/\/mllj2j8xvfl0.i.optimole.com\/cb:c5QE.37290\/w:1105\/h:443\/q:mauto\/f:best\/https:\/\/themeisle.com\/blog\/wp-content\/uploads\/2018\/11\/webp.png 1105w, https:\/\/mllj2j8xvfl0.i.optimole.com\/cb:c5QE.37290\/w:300\/h:120\/q:mauto\/f:best\/https:\/\/themeisle.com\/blog\/wp-content\/uploads\/2018\/11\/webp.png 300w, https:\/\/mllj2j8xvfl0.i.optimole.com\/cb:c5QE.37290\/w:768\/h:308\/q:mauto\/f:best\/https:\/\/themeisle.com\/blog\/wp-content\/uploads\/2018\/11\/webp.png 768w, https:\/\/mllj2j8xvfl0.i.optimole.com\/cb:c5QE.37290\/w:1024\/h:411\/q:mauto\/f:best\/https:\/\/themeisle.com\/blog\/wp-content\/uploads\/2018\/11\/webp.png 1024w, https:\/\/mllj2j8xvfl0.i.optimole.com\/cb:c5QE.37290\/w:50\/h:20\/q:mauto\/f:best\/https:\/\/themeisle.com\/blog\/wp-content\/uploads\/2018\/11\/webp.png 50w, https:\/\/mllj2j8xvfl0.i.optimole.com\/cb:c5QE.37290\/w:480\/h:192\/q:mauto\/f:best\/https:\/\/themeisle.com\/blog\/wp-content\/uploads\/2018\/11\/webp.png 480w, https:\/\/mllj2j8xvfl0.i.optimole.com\/cb:c5QE.37290\/w:794\/h:318\/q:mauto\/f:best\/https:\/\/themeisle.com\/blog\/wp-content\/uploads\/2018\/11\/webp.png 794w, https:\/\/mllj2j8xvfl0.i.optimole.com\/cb:c5QE.37290\/w:296\/h:119\/q:mauto\/f:best\/https:\/\/themeisle.com\/blog\/wp-content\/uploads\/2018\/11\/webp.png 296w, https:\/\/mllj2j8xvfl0.i.optimole.com\/cb:c5QE.37290\/w:390\/h:156\/q:mauto\/f:best\/https:\/\/themeisle.com\/blog\/wp-content\/uploads\/2018\/11\/webp.png 390w, https:\/\/mllj2j8xvfl0.i.optimole.com\/cb:c5QE.37290\/w:270\/h:108\/q:mauto\/f:best\/https:\/\/themeisle.com\/blog\/wp-content\/uploads\/2018\/11\/webp.png 270w, https:\/\/mllj2j8xvfl0.i.optimole.com\/cb:c5QE.37290\/w:1105\/h:443\/q:mauto\/f:best\/dpr:2\/https:\/\/themeisle.com\/blog\/wp-content\/uploads\/2018\/11\/webp.png 2x\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<p>You can view a full side-by-side comparison at <a href=\"https:\/\/developers.google.com\/speed\/webp\/gallery1\" target=\"_blank\" rel=\"noopener\">the WebP Gallery<\/a>.<br \/>\n<div class=\"su-divider su-divider-style-dotted\" style=\"margin:40px 0;border-width:1px;border-color:#999999\"><\/div>\n<h2 id=\"pros-and-cons-webp\">The pros and cons of using WebP images on your site<\/h2>\n<p>Now that we\u2019ve answered the question of \u201cwhat is WebP?\u201d, let\u2019s talk about why it matters by discussing the pros and cons of WebP images.<br \/>\n<div class=\"su-divider su-divider-style-default\" style=\"margin:40px 0;border-width:15px;border-color:#4267cf\"><\/div>\n<h3>Pros of WebP images<\/h3>\n<p>As we\u2019ve alluded to already, the primary goal of this image format is to provide a web-focused option that\u2019s superior to both PNG and JPEG in most situations.<\/p>\n<p>Image files take up space \u2013 no matter how they\u2019re saved. The more images and other media you add to your site, the greater the chance of laggy performance. <a href=\"https:\/\/themeisle.com\/blog\/speed-up-wordpress-quick-wins\/\">Keeping your pages loading fast<\/a> is incredibly important, since slow speeds drive visitors away before they\u2019ve even seen what you have to offer.<\/p>\n<p><a href=\"https:\/\/themeisle.com\/blog\/wordpress-image-optimizer-plugins-compared\/\">Compressing image files<\/a> makes them smaller and more efficient, but usually comes at a loss of quality. In general, the more you compress an image, the worse it looks. However, the particular file type you\u2019re using has an impact on how extreme the effect is.<\/p>\n<p>Images saved in a WebP format can be made significantly smaller than JPEGs and PNGs at the same quality. Again, lossless WebP images function as a replacement for PNGs, and the files are about 26% smaller. Lossy WebP images, on the other hand, are around 25-34% smaller than JPEGs.<\/p>\n<p>Also notable is that both types of WebP images support transparency. Transparent images are incredibly useful on the web \u2013 you can use them for logos and other branding, just as one example. JPEGs don\u2019t offer transparency as a feature, but lossy WebP images do.<br \/>\n<div class=\"su-divider su-divider-style-default\" style=\"margin:40px 0;border-width:15px;border-color:#4267cf\"><\/div>\n<h3>Cons of WebP images<\/h3>\n<p>If WebP offers so many benefits, why isn\u2019t it being used by more people?<\/p>\n<p>In the past, the primary drawback used to be that WebP images weren&#8217;t&nbsp;supported by all browsers. In fact, when we originally wrote this article, that exact reason was written here. However, browsers have rapidly caught on, and as of right now, there is an <a href=\"https:\/\/caniuse.com\/webp\" rel=\"noopener\" target=\"_blank\">over 97% adoption rate<\/a> for the WebP format.<\/p>\n<p>Long story short, unless you are browsing the internet with an ancient dinosaur browser, then you&#8217;ll have no problem seeing WebP images on websites.<\/p>\n<p>Okay, so if browser compatibility isn&#8217;t an issue anymore, then does WebP even have any cons?<\/p>\n<p>Unfortunately, yes, but it&#8217;s not so much a con with WebP itself, as it is with other services being slow to adopt its use. In other words, the same problem that used to exist with browser compatibility still exists, but with other web tools like <a href=\"https:\/\/themeisle.com\/blog\/what-is-a-content-management-system-cms\/\">content management systems (CMS)<\/a> and project management software.<\/p>\n<p>WebP is also not the best choice for certain niche sites like photography portfolios. To nobody&#8217;s surprise, photographers often prefer to portray the highest possible quality images in their galleries. They will gladly sacrifice some site speed in exchange for showing off their work in its fully pixelated glory, and for that, WebP just isn&#8217;t going to cut it.<br \/>\n<div class=\"su-divider su-divider-style-dotted\" style=\"margin:40px 0;border-width:1px;border-color:#999999\"><\/div>\n<h2 id=\"how-to-start-using-webp\">How to use WebP images on your WordPress site<\/h2>\n<p>Of course, as a WordPress user, it\u2019s not enough to ask \u201cwhat is WebP?\u201d You also need to know whether this type of image can be used alongside WordPress. As mentioned above, not every <a href=\"https:\/\/themeisle.com\/blog\/best-website-builder\/\">website builder<\/a> and content management system (CMS) supports the WebP format.<\/p>\n<p>Luckily, if you&#8217;re part of the 42.5% of the internet that uses WordPress to build their websites, then you won&#8217;t have any problems using WebP. That&#8217;s because <a href=\"https:\/\/make.wordpress.org\/core\/2021\/06\/07\/wordpress-5-8-adds-webp-support\/\" rel=\"noopener\" target=\"_blank\">starting with WordPress 5.8<\/a>, the world&#8217;s most popular CMS also began to support WebP by default. As long as you&#8217;re using the latest version of WordPress, then you won\u2019t need to use a third-party plugin just to use WebP images.<\/p>\n<p>Having said that, using a third party plugin isn&#8217;t exactly a bad idea. More on that below&#8230;<br \/>\n<div class=\"su-divider su-divider-style-default\" style=\"margin:40px 0;border-width:15px;border-color:#4267cf\"><\/div>\n<h3>Optimole<\/h3>\n<p>Optimole is our image optimization solution that has a lot of cool features under the hood. Apart from being able to have all your images optimized automatically and then get them served through a CDN, you also get to experience the benefits of WebP images.<\/p>\n<p>The way Optimole enables WebP images is pretty neat. The plugin converts your images to WebP automatically if the visitor&#8217;s browser supports them. As we&#8217;ve established, the chances of a visitor&#8217;s browser not supporting WebP in 2023 is very low. However, if for some odd reason, the browser doesn&#8217;t support WebP, then Optimole will render the originally uploaded version of the image.<\/p>\n<div class=\"wp-pic-wrapper align-center large\" style=\"margin:20px 0;\"><div class=\"wp-pic large plugin scheme2\"  id=\"wp-pic-optimole-wp\" ><div class=\"wp-pic-large\" style=\"display: none;\">\n\t<div class=\"wp-pic-large-content\">\n\t\t<a rel=\"nofollow\" class=\"wp-pic-asset-bg\" href=\"https:\/\/wordpress.org\/plugins\/optimole-wp\/\" target=\"_blank\" title=\"WordPress.org Plugin Page\">\n\t\t\t<img data-opt-id=1339657174  fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/ps.w.org\/optimole-wp\/assets\/banner-772x250.jpg?rev=3019688\" alt=\"Optimole \u2013 Optimize Images | Convert WebP &amp; AVIF | CDN &amp; Lazy Load | Image Optimization\" \/>\t\t\t<span class=\"wp-pic-asset-bg-title\"><span>Optimole \u2013 Optimize Images | Convert WebP &amp; AVIF | CDN &amp; Lazy Load | Image Optimization<\/span><\/span>\n\t\t<\/a>\n\t\t<div class=\"wp-pic-half-first\">\n\t\t\t<a rel=\"nofollow\" class=\"wp-pic-logo\" href=\"https:\/\/wordpress.org\/plugins\/optimole-wp\/\" style=\"background-image: url(https:\/\/ps.w.org\/optimole-wp\/assets\/icon-256x256.gif?rev=3013666 );\" target=\"_blank\" title=\"WordPress.org Plugin Page\"><\/a>\n\t\t\t<p class=\"wp-pic-author\">Author(s):\t\t\t\t\t\t\t\t\t<a rel=\"nofollow\" href=\"https:\/\/profiles.wordpress.org\/optimole\/\">Optimole<\/a>\n\t\t\t\t\t\t\t<\/p>\n\t\t\t<p class=\"wp-pic-version\"><span>Current Version:<\/span> 4.0.3<\/p>\n\t\t\t<p class=\"wp-pic-updated\"><span>Last Updated:<\/span> May 27, 2025<\/p>\n\t\t\t<p><a rel=\"nofollow\" class=\"wp-pic-dl-link\" href=\"https:\/\/downloads.wordpress.org\/plugin\/optimole-wp.4.0.3.zip\" title=\"Direct download\">Direct Download<\/a><\/p>\n\t\t\t\t\t<\/div>\n\t\t<div class=\"wp-pic-half-last\">\n\t\t\t<div class=\"wp-pic-bottom\">\n\t\t\t\t<div class=\"wp-pic-bar\">\n\t\t\t\t\t<a rel=\"nofollow\" href=\"https:\/\/wordpress.org\/support\/view\/plugin-reviews\/optimole-wp\" class=\"wp-pic-rating\" target=\"_blank\" title=\"Ratings\">\n\t\t\t\t\t\t94%<em>Ratings<\/em>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t<a rel=\"nofollow\" href=\"https:\/\/downloads.wordpress.org\/plugin\/optimole-wp.4.0.3.zip\" class=\"wp-pic-downloaded\" target=\"_blank\" title=\"Direct download\">\n\t\t\t\t\t\t200,000+<em>Installs<\/em>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t<a rel=\"nofollow\" href=\"https:\/\/wordpress.org\/plugins\/optimole-wp\/\" class=\"wp-pic-requires\" target=\"_blank\" title=\"WordPress.org Plugin Page\">\n\t\t\t\t\t\tWP 5.5+<em>Requires<\/em>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n<\/div><\/div><!-- .wp-pic-wrapper--><link rel='stylesheet' id='dashicons-css' href='https:\/\/themeisle.com\/blog\/wp-includes\/css\/dashicons.min.css?ver=6.8.5' type='text\/css' media='all' \/>\n<link rel='stylesheet' id='wppic-style-css' href='https:\/\/themeisle.com\/blog\/wp-content\/plugins\/wp-plugin-info-card\/dist\/wppic-styles.css?ver=6.1.1' type='text\/css' media='all' \/>\n<script type=\"text\/javascript\" src=\"https:\/\/themeisle.com\/blog\/wp-includes\/js\/jquery\/jquery.min.js?ver=3.7.1\" id=\"jquery-core-js\"><\/script>\n<script type=\"text\/javascript\" src=\"https:\/\/themeisle.com\/blog\/wp-includes\/js\/jquery\/jquery-migrate.min.js?ver=3.4.1\" id=\"jquery-migrate-js\"><\/script>\n<script type=\"text\/javascript\" id=\"wppic-script-js-extra\">\n\/* <![CDATA[ *\/\nvar wppicAjax = {\"ajaxurl\":\"https:\\\/\\\/themeisle.com\\\/blog\\\/wp-admin\\\/admin-ajax.php\"};\n\/* ]]> *\/\n<\/script>\n<script type=\"text\/javascript\" src=\"https:\/\/themeisle.com\/blog\/wp-content\/plugins\/wp-plugin-info-card\/assets\/js\/wppic-script.min.js?ver=6.1.1\" id=\"wppic-script-js\"><\/script>\n\n<p>There are also alternative tools that enable WebP images if you&#8217;d like to experiment more with what&#8217;s out there.<\/p>\n<ul>\n<li><a href=\"https:\/\/wordpress.org\/plugins\/jetpack\/\" target=\"_blank\" rel=\"noopener\">Jetpack<\/a> has an image CDN module that works with WebP images.<\/li>\n<li>You can also enable WebP by combining <a href=\"https:\/\/wordpress.org\/plugins\/shortpixel-image-optimiser\/\" target=\"_blank\" rel=\"noopener\">ShortPixel<\/a> \/ <a href=\"https:\/\/wordpress.org\/plugins\/ewww-image-optimizer\/\" target=\"_blank\" rel=\"noopener\">EWWW Image Optimizer<\/a> with <a href=\"https:\/\/wordpress.org\/plugins\/cache-enabler\/\" target=\"_blank\" rel=\"noopener\">Cache Enabler<\/a>.
