What does BMP to PNG conversion do?

BMP files are simple bitmap images, while PNG is a compressed, widely supported format that usually produces smaller files and better web compatibility. This tool converts between the two locally in your browser.

Use BMP to PNG when you want a lighter file for the web, or PNG to BMP when you need a format that is easy to inspect and exchange with older software.

How to use it

BMP to PNG

Choose a BMP file, preview it, and click Convert to generate a PNG download.

PNG to BMP

Choose a PNG file, preview it, and click Convert to encode a BMP file with the same dimensions.

Good fit

  • Good for web workflows where you want to convert legacy BMP assets into PNG.
  • Useful when a tool or system expects bitmap format and you need a quick PNG back to BMP export.
  • Handy for verifying image dimensions and previewing the result before you download it.

Notes

PNG to BMP conversion is handled by drawing the image to a canvas and then encoding it as a 32-bit BMP. That keeps the conversion local and generally preserves alpha, though some older BMP viewers may ignore it.

Tip: if your source image has transparency, review the converted BMP in the target app to confirm how it handles alpha.
