Why convert BMP to PNG?
PNG keeps every pixel exactly like BMP does, but with lossless compression, so the file is far smaller.
About BMP
BMP is an old, uncompressed Windows image format. Files are very large, so converting to a modern format saves a lot of space.
About PNG
PNG is a lossless image format that keeps sharp edges and transparency. It is ideal for screenshots, logos and graphics, but photos can become very large.
