Why WebP beats PNG on the web
WebP is the modern image format built for the web: it stores the same picture as a PNG in noticeably less space, usually 25 to 35% smaller, which means faster page loads and better Core Web Vitals. Every current browser supports it.
Transparency comes along
Unlike JPG, WebP has a real alpha channel, so transparent PNGs stay transparent after converting. You get the smaller file and keep the see-through background, which makes it a clean drop-in replacement for PNG site assets, icons and logos.
When to keep the PNG
A few older tools and some email clients still don't read WebP. If a file needs maximum compatibility (emailing to unknown software, say), PNG or JPG is the safer pick. For anything that lives on the web, WebP is the better default.
