About the two formats
PNG
PNG was designed as a lossless web format: it stores every pixel exactly and supports full transparency. That makes it the default choice for logos, icons, screenshots and any graphic with sharp edges or text.
WebP
WebP is Google's web-first format, supported by every modern browser. It compresses both photos and graphics 25-80% smaller than JPG or PNG at the same visual quality, and supports transparency and animation.
