WebP Injection 🖼️

Raw assets are a liability for mobile performance. Using PHP GD library, we intercept high-resolution image requests and transcode them into WebP format before they reach the user's browser, significantly reducing the LCP (Largest Contentful Paint) metric. ⌨️

WebP Transcoder 🧩

This PHP script checks if a WebP version of the image exists. If not, it generates it using the imagewebp() function, ensuring that the heavy compression only happens once. 🧪

<?php
function get_optimized_img($source) {
    $target = str_replace(['.jpg', '.png'], '.webp', $source);

    if (!file_exists($target)) {
        $img = imagecreatefromjpeg($source);
        imagewebp($img, $target, 80); // 80% Quality
        imagedestroy($img);
    }

    return $target;
}

echo '<img src="' . get_optimized_img('hero.jpg') . '">';
?>

Automating the asset pipeline ensures that your technical log remains fast even with high-resolution diagrams. It removes the friction of manual optimization and guarantees that every visitor receives the most efficient version of your content. 🚀
