<p>Squidge is a FREE WordpPress Plugin built for developers in mind compressing and convert images using jpegoptim,<br />
optipng, cwebp, and libavif. It’s extremley simple to use and is designed to increase PSI and boost rankings.</p>
<h3>Why?</h3>
<p>Image compression in WordPress can be costly, confusing and sometimes just simply don’t work. We have aimed to simplify<br />
the process by requiring the developer to install the required package on the operating system and Squidge does the<br />
hard work for you.</p>
<ul>
<li><strong>IT’S FREE</strong></li>
<li>Unlimited file size, no limits.</li>
<li>Optimised for your site to rank.</li>
<li>CLI to regenerate all of your media files.</li>
<li>Helper functions to output images in templates.</li>
<li>Uses the native <code>cwebp</code> and <code>libavif</code> libraries.</li>
</ul>
<h3>What does Squidge do?</h3>
<p>Squidge compresses and converts image files when the user has uploaded a file to WordPress.</p>
<ul>
<li>Compresses JPG images using <code>jpegoptim</code>.</li>
<li>Compresses PNG images using <code>optipng</code>.</li>
<li>Converts JPG and PNG images to <code>.webp</code> files using <code>cwebp</code> with the appended extension  e.g. <code>image.jpg.webp</code>.</li>
<li>Converts JPG and PNG images to <code>.avif</code> files using <code>libavif</code> with the appended extension  e.g. <code>image.jpg.avif</code>.</li>
</ul>
<h3>Render Images</h3>
<p>To render images in templates, you can either set up nginx or apache rules to serve images dynamically or used the<br />
    squidge_image helper function. This dynamically checks if an <code>.avif</code> or <code>.webp</code> file is available on the file system<br />
and returns the output.</p>
<h3>Function</h3>
<pre><code>/**
 * Returns a <picture> element with source media for the standard file passed
 * (such as a JPG), the .avif file, the .webp file (if to exist on the file system).
 *
 * Appropriate <source> elements for image sizes with max widths.
 * Finally, the main be outputted with alt and title text.
 *
 * - If lazy is true, the data-src or data-srcset will be appended.
 * - If a class is set, the class will be outputted on the <picture> element.
 *
 * @param $image_id
 * @param string $class
 * @param false $lazy
 * @return string
 */
function squidge_image($image_id, $class = '', $lazy = false)
</code></pre>
<h3>Output</h3>
<pre><code><picture class="picture">
    
    <source media="(max-width: 400px)" srcset="/sample-image.jpg.avif" type="image/avif">
    <source media="(max-width: 400px)" srcset="/sample-image.jpg.webp" type="image/webp">
    <source media="(max-width: 400px)" srcset="/sample-image.jpg">
    
    <source srcset="/sample-image.jpg.avif" type="image/avif">
    <source srcset="/sample-image.jpg.webp" type="image/webp">
    
    <img src="/sample-image.jpg" alt="Alt text" title="Sample JPG">
</picture>

<h4>About the plugin</h4>
<ul>
<li>You can use your CheetahO API key on as many sites/blogs as you like. We have no per-site license.</li>
<li>All images uploaded throught the media uploader are optimized on-the-fly. All generated thumbnails are optimized too.</li>
<li>All images already present in the media library can be optimized individually, or using the Bulk Action.</li>
<li>All optimization is carried out by sending images to CheetahO and pulling the optimized files to your WordPress installation.</li>
<li>All full size images can be resized/rescaled before optimization by setting maximum width and height.</li>
<li>To use this plugin, you must obtain a full API key from CheetahO <a href="https://app.cheetaho.com/api-credentials?utm_source=wordpress-plugin&utm_medium=readme" rel="nofollow ugc">panel</a>.</li>
</ul>
<p>Once you have obtained your credentials, from your WordPress admin, go to the settings page and there you can enter your API credentials, and select your optimization preferences. Once you have done this, click on <strong>Save</strong>. If everything is in order, it will simply say “settings saved” and give you a reassuring green tick that your credentials are valid. You can now start optimizing images from within Media Library. Any image you upload from now on, through any of the media upload screens will be optimized on-the-fly.</p>
