About PNG
PNG is a lossless raster format with optional transparency. Pixels are preserved exactly, so it is the usual choice for screenshots, UI, logos, and any image that needs a clean alpha channel.
About WebP
WebP is a modern web image format from Google. It can encode lossy or lossless images and supports transparency, often beating JPG and PNG on size at similar visual quality.
