Why are BMP files so large?

BMP files are typically uncompressed, storing every pixel individually. A 1920×1080 image at 24-bit color is about 6MB in BMP format versus 200-500KB in JPG.

Should I convert BMP when resizing?

Yes! Unless you specifically need BMP format, converting to JPG, PNG, or WEBP during resize will dramatically reduce file sizes without visible quality loss.
