Create a straightforward Windows bitmap from PNG artwork while choosing whether transparent pixels remain in a 32-bit file or are flattened into RGB.

What PNG to BMP changes

BMP output stores decoded PNG pixels in a Windows bitmap. Choose 32-bit RGBA when the destination supports an alpha channel, or 24-bit RGB when compatibility matters more than transparency. The BMP will normally be much larger than the PNG.

PNG to BMP questions

Will PNG transparency survive in BMP?

Choose 32-bit RGBA to keep alpha data. A 24-bit BMP has no alpha channel and uses the selected background instead.
