Why convert BMP to WebP?
BMP stores pixels with little or no compression, so files are very large. Converting BMP to a modern format typically shrinks files by 90% or more.
WebP files are usually 25–35% smaller than JPG at the same visual quality. Converting images to WebP makes websites and online stores load faster, which also helps search rankings.
