Convert PNG to JPG — What Happens to Transparency?
JPG does not support transparency. When converting a PNG with a transparent background to JPG, the transparent areas become white (or the colour you specify). If you need to keep transparency, convert to WebP instead — it supports transparency and is smaller than PNG.
Convert Images to WebP for Faster Websites
Google recommends serving images in WebP format for faster page loads. WebP images are 25–35% smaller than equivalent JPG/PNG files at the same visual quality. All modern browsers (Chrome, Firefox, Safari, Edge) support WebP. Converting your website images to WebP can significantly improve Google PageSpeed scores.
