About BMP to PNG conversion

BMP files are uncompressed, so they're large. PNG stores the same pixels with lossless compression, so you get a file that looks identical and is usually a fraction of the size.

Nothing is lost in this conversion. It's a good first step when you have old BMP screenshots or exports from legacy software.
