<p>Fast, simple & free plugin to automatically convert and serve WebP & AVIF images.</p>
<h4>Features</h4>
<ul>
<li>Automatically convert and serve WebP/AVIF images.</li>
<li>Increase your Google Pagespeed.</li>
<li>Only images which are really used will be converted, does <strong>not</strong> convert the whole media library.</li>
<li>WebP/AVIF quality is adjustable (default 100% = no quality loss)</li>
<li>No image URLs are changed, solution is purely based on .htaccess rewrite rules.</li>
<li>Serve original format in case the browser does not support WebP/AVIF (relying on the “Accept” header).</li>
<li>The following source formats are supported: JP(E)G, PNG, GIF, BMP.</li>
<li>Extra feature: WebP images are served as PNG when the browser/client does not support WebP (e.g. Microsoft Outlook).</li>
</ul>
<h4>Browser support</h4>
<ul>
<li>WebP: all modern browsers</li>
<li>AVIF: Chrome, Firefox, Safari (Edge doesn’t support AVIF yet)</li>
</ul>
<h4>Good to know</h4>
<ul>
<li>It may take a few minutes before the WebP/AVIF images are generated after activating the plugin.</li>
<li>AVIF is a relatively new format, and not widely supported yet on servers. This depends on your server configuration (see Server requirements).</li>
<li>Generating AVIF images is CPU-intensive, and may take a while.</li>
<li>WebP/AVIF format is only served when this format is smaller than the original file. Depending on the image, WebP/AVIF is not always the most efficient format.</li>
<li>Animated GIF-images are not supported yet as GDlib/ImageMagick don’t have support for it</li>
</ul>
<h4>How the plugin works</h4>
<p>The plugin does <strong>nothing</strong> until the first image is requested. Here is the conversion flow.</p>
<ol>
<li>Original image is requested in browser</li>
<li>Image is added to the conversion queue, original image is still served.</li>
<li>Conversion queue is processed in background, queued images are converted to WebP/AVIF format.</li>
<li>When the image is requested now, and the browser supports WebP and/or AVIF, the WebP/AVIF image is served.</li>
</ol>
