<p>Automatically optimize uploaded images (jpg, png, gif, webp, svg, avif) using the <a href="https://github.com/spatie/image-optimizer" rel="nofollow ugc">Spatie image-optimizer library</a> and binary files on your host system.</p>
<p>New uploaded images with all image sizes (thumbnails) will be optimized automatically.</p>
<p>Previously uploaded images can be updated in two ways:</p>
<ol>
<li>Use the command line interface (cli) and run <code>wp media regenerate</code>, which also triggers the optimization chain. If you don’t have cli access, some other plugin, that regenerates existing thumbnails should work, too (not tested, yet).</li>
<li>The media library has a new column “File size” in the list view, which displays the new and the old file size. If an image is not optimized, there is a link named “Optimize” to run the optimizer directly.</li>
</ol>
<p><strong>Warning:</strong> Images are replaced with the optimized ones. Create a backup before testing this plugin. If this is a deal-breaker for you, don’t use it.</p>
<p><strong>Important:</strong> If the needed binary files aren’t installed, this plugin won’t optimize anything. Don’t use it, if you don’t know, how to install them or if your web hoster doesn’t provide them.</p>
<p><strong>Notice:</strong> WordPress has no support for SVG files. Technically this plugin can optimize them, but I didn’t run any tests with plugins, that add SVG support to WordPress. I was able to optimize svg files automatically in a local test setup (see <a href="https://codeberg.org/raffaelj/wordpress-another-simple-image-optimizer/src/branch/main/tests/prepare-and-run-tests.sh" rel="nofollow ugc"><code>prepare-and-run-tests.sh</code> in the tests folder</a> and search for <code>enable_svg_avif_upload</code>).</p>

<h3>Requirements</h3>
<ul>
<li>PHP function <code>proc_open</code> must be enabled (some web hosts disable it via <code>php.ini</code>)</li>
</ul>
<h3>Settings</h3>
<p>Quality settings can be adjusted with constants in <code>wp-config.php</code>:</p>
<p>Set quality for resizing images (GD/Imagick)</p>
<ul>
<li><code>define('ASIO_RESIZE_QUALITY_JPEG', 100); // default: 82</code></li>
<li><code>define('ASIO_RESIZE_QUALITY_WEBP', 100); // default: 86</code></li>
</ul>
<p>Set quality of optimizers</p>
<ul>
<li><code>define('ASIO_QUALITY_JPEGOPTIM', 90); // default: 85</code></li>
<li><code>define('ASIO_QUALITY_PNGQUANT',  90); // default: 85</code></li>
<li><code>define('ASIO_QUALITY_CWEBP',     85); // default: 90</code></li>
<li><code>define('ASIO_QUALITY_AVIFENC',   70); // default: 63</code></li>
</ul>
<h3>Optimization tools</h3>
