How BMP compression works
BMP is a raster format that often stores uncompressed pixel data. Re-encoding a bitmap with a quality setting can remove unnecessary weight from photographic images.
If you need maximum compatibility with browsers, JPG and WebP are usually more practical delivery formats than BMP.
