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 AVIF
AVIF is a next-generation image format based on the AV1 video codec. It typically yields smaller files than WebP or JPG at similar quality and supports transparency and high bit depth.
