Questions about BMP and PNG.
Check the format behavior, limitations, and follow-up options before processing a real file.
PNG stores exactly the same pixels as BMP but compresses them, typically shrinking files substantially with no quality loss. Unless a specific program demands BMP, PNG is the better everyday container: smaller, web-ready, and able to hold transparency for future edits.
