    BMP to PNG: cut the weight by 5× without losing quality

    BMP is a legacy uncompressed Windows format: a 24 MB BMP can become a 5 MB PNG with no visible loss. Both are lossless, but PNG uses smart algorithmic compression that typically divides the weight by 4–5× on a normal image.

    Universal compatibility, unlike BMP

    Every browser, website, social network, and modern app opens PNG. BMP is stuck on Windows and legacy software — not natively rendered on iOS or by Instagram, for example.

    Transparency preserved when present

    Some BMPs embed an alpha channel (32-bit BMP): the PNG conversion preserves it. For graphic or web use, that transparency lets you drop the image over colored backgrounds without further cut-out work.
