What is BMP?
BMP. BMP (Bitmap) is an uncompressed Windows-era image format. Files are huge but lossless.
Mostly legacy — Windows utilities, scanners, old software.
What is PNG?
PNG. PNG is a lossless image format with full transparency support. It produces larger files than JPEG but preserves every pixel exactly.
Used for screenshots, logos, graphics, and any image where pixel-perfect output matters.
Why convert BMP → PNG?
Universal compatibility
PNG works on every device, browser, and operating system. No more "unsupported format" errors.
Smaller file size
Depending on the source, PNG often produces smaller files than BMP — better for sharing and uploading.
