Practical Tips

• BMP files are much larger than PNGs — a 1 MB PNG can become 10-20 MB as BMP. Only convert when you specifically need BMP format.
• Use 24-bit depth for maximum compatibility with older software that doesn't support alpha channels.
• Convert back to PNG with BMP to PNG when you're done editing in legacy applications.

Why would I need BMP format?

BMP is required by some legacy Windows applications, embedded systems, industrial equipment, and certain game engines that expect uncompressed bitmap data.

Does BMP support transparency?

32-bit BMP supports an alpha channel, but many older applications ignore it. For reliable transparency, stay with PNG.
