<li><strong>DNS Preconnects</strong>: Accelerates resource fetching, reduces the access time to external resources.</li>
<li><strong>Font Processing</strong>: All the techniques to accelerate the processing and delivery of fonts are employed, e.g. font subsetting, font loading control, font compression, font embedding (lower CLS result).</li>
<li><strong>Image Resizing & Optimization</strong>: Images are automatically resized to fit their placeholders, optimized, and delivered through the ShortPixel CDN.</li>
<li><strong>Automatic Next-Gen Images Delivery</strong>: Based on the visitor’s browser capabilities, original JPG, PNG, or GIF images are converted to and served as WebP or AVIF when supported. For browsers without support, the original format is provided.</li>

<h3>Hooks</h3>
<p>FastPixel provides WordPress action hooks that allow developers to programmatically trigger cache purges and react to cache events. This is useful when integrating FastPixel with custom plugins, WooCommerce, ACF, or any workflow that modifies content outside the standard WordPress editor.</p>
<p>Example hooks:<br />
do_action(‘fastpixel/purge/all’); – Purges the entire site cache.<br />
do_action(‘fastpixel/purge/single’, [‘id’ => 123]); – Purges the cache for a single post, page, or taxonomy term.<br />
do_action(‘fastpixel/purge/url’, ‘https://example.com/my-landing-page/’); – Purges the cache for a specific URL.</p>
