<p>This plugin improves page load time and increases your Google PageSpeed Score. It works with oEmbed and replaces embedded Youtube and Vimeo videos with a clickable preview image.<br />
By loading videos only when the user clicks on the preview image, no unnecessary JavaScript is loaded. Especially on sites with many embedded videos this will make your visitors happy. Additionally, all Youtube videos are loaded in a privacy-enhanced mode using the “https://www.youtube-nocookie.com” embed URL.</p>
<p>This plugin works for your existing YouTube and Vimeo blocks. No vendor lock-in and no custom shortcodes: Easily turn the plugin on and off anytime.</p>

Lazy Load for Videos

We have pages with multiple videos and that slowed down the page load and increased network traffic. This plugin improved it a lot. Reduced blocking of some pages with seconds and reduced the page load from 3MB to 1,3MB.



Works great

Hi there,
your plugin ist really great! It kills several problems with one stone for me.
Very nice!
Keep up your good work and thanks very mutch for this plugin.

:-)

Very cool!


I noticed Squarespace has a much slicker way of loading and showing embedded videos, and I wanted it.   This plugin works perfectly to provide it so that my video portfolio page loads faster and looks better.  Thanks to the developer!


Simple solution for making video pages fast like Squarespace

Boost page speed by replacing embedded YouTube and Vimeo videos with a clickable preview image. Video scripts only load on click.

WordPress.org

<p>This plugin optimizes the loading of images (and videos) with prioritization to improve <a href="https://web.dev/articles/lcp" rel="nofollow ugc">Largest Contentful Paint</a> (LCP), lazy loading, and more accurate image size selection.</p>
<p>The current optimizations include:</p>
<ol>
<li>Add breakpoint-specific <code>fetchpriority=high</code> preload links (both as <code>LINK[rel=preload]</code> elements and <code>Link</code> response headers) for image URLs of LCP elements:
<ol>
<li>An <code>IMG</code> element, including the <code>srcset</code>/<code>sizes</code> attributes supplied as <code>imagesrcset</code>/<code>imagesizes</code> on the <code>LINK</code>.</li>
<li>The first <code>SOURCE</code> element with a <code>type</code> attribute in a <code>PICTURE</code> element. (Art-directed <code>PICTURE</code> elements using media queries are not supported.)</li>
<li>An element with a CSS <code>background-image</code> inline <code>style</code> attribute.</li>
<li>An element with a CSS <code>background-image</code> applied with a stylesheet (when the image is from an allowed origin).</li>
<li>A <code>VIDEO</code> element’s <code>poster</code> image.</li>
</ol>
</li>
<li>Ensure <code>fetchpriority=high</code> is only added to an <code>IMG</code> when it is the LCP element across all responsive breakpoints.</li>
<li>Add <code>fetchpriority=low</code> to <code>IMG</code> tags which appear in the initial viewport but are not visible, such as when they are subsequent carousel slides.</li>
<li>Lazy loading:
<ol>
<li>Apply lazy loading to <code>IMG</code> tags based on whether they appear in any breakpoint’s initial viewport.</li>
<li>Implement lazy loading of CSS background images added via inline <code>style</code> attributes.</li>
<li>Lazy-load <code>VIDEO</code> tags by setting the appropriate attributes based on whether they appear in the initial viewport. If a <code>VIDEO</code> is the LCP element, it gets <code>preload=auto</code>; if it is in an initial viewport, the <code>preload=metadata</code> default is left; if it is not in an initial viewport, it gets <code>preload=none</code>. Lazy-loaded videos also get initial <code>preload</code>, <code>autoplay</code>, and <code>poster</code> attributes restored when the <code>VIDEO</code> is going to enter the viewport.</li>
</ol>
</li>
<li>Responsive image sizes:
<ol>
<li>Ensure <a href="https://make.wordpress.org/core/2024/10/18/auto-sizes-for-lazy-loaded-images-in-wordpress-6-7/" rel="nofollow ugc"><code>sizes=auto</code></a> is set on <code>IMG</code> tags after setting correct lazy-loading (above).</li>
<li>~~Compute the <code>sizes</code> attribute using the widths of an image collected from URL Metrics for each breakpoint (when not lazy-loaded since then handled by <code>sizes=auto</code>).~~ (This has been removed due to an <a href="https://github.com/WordPress/performance/issues/2098" rel="nofollow ugc">issue</a>; use <a href="https://wordpress.org/plugins/auto-sizes/" rel="ugc">Enhanced Responsive Images instead</a>.)</li>
</ol>
</li>
<li>Reduce the size of the <code>poster</code> image of a <code>VIDEO</code> from full size to the size appropriate for the maximum width of the video (on desktop).</li>
</ol>
<p><strong>This plugin requires the <a href="https://wordpress.org/plugins/optimization-detective/" rel="ugc">Optimization Detective</a> plugin as a dependency.</strong> Please refer to that plugin for additional background on how this plugin works as well as additional developer options.</p>
<p>👉 <strong>Note:</strong> This plugin optimizes pages for actual visitors, and it depends on visitors to optimize pages. As such, you won’t see optimizations applied immediately after activating the plugin. Please wait for URL Metrics to be gathered for both mobile and desktop visits. And since administrator users are not normal visitors typically, optimizations are not applied for admins by default.</p>
<p>Your site must have the <strong>REST API accessible</strong> to unauthenticated frontend visitors since this is how metrics are collected about how a page should be optimized. There are currently <strong>no settings</strong> and no user interface for this plugin since it is designed to work without any configuration.</p>


Image Prioritizer

Prioritizes the loading of images and videos based on how they appear to actual visitors: adds fetchpriority, preloads, lazy-loads, and sets sizes.
