Why WebP? WebP is a modern image format by Google that provides:

25–35% smaller file size compared to JPEG Better quality at the same file size Supported by all modern browsers (Chrome, Firefox, Safari, Edge) Faster page load times → better SEO and Core Web Vitals

Configuration To change the watermark, simply replace watermark.png in the root directory with your own logo/image (PNG with transparency recommended). To adjust watermark size or opacity, edit these lines in index.php: php$watermark->scale(width: 100); // Change watermark width (px) $image->place($watermark, "center", 20, 20, 50); // Last param = opacity (0-100)
