About the two formats
BMP
BMP stores every pixel with no compression at all, so even simple images take megabytes. It’s mostly found in old software, scanners and exports.
WebP
WebP was built to make web images smaller than JPG and PNG at the same quality. Websites use it widely, which is why images you save from the web are often WebP.
