Why convert BMP to PNG?
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.
PNG keeps every pixel exactly and supports transparent backgrounds, which makes it the right choice for screenshots, logos, graphics with text and anything you plan to edit further.
