PNG to BMP Conversion

PNG files use lossless compression. This means you can edit and save a PNG as many times as you want without losing any quality. PNGs also support transparency, allowing parts of your image to be see-through. This makes PNG ideal for logos, graphics, and any image that needs to be layered over other content.

BMP (Bitmap) is an uncompressed raster image format. It stores color data for every pixel without any compression, resulting in very large file sizes. While it offers high quality, its large size makes it impractical for web use.

Frequently Asked Questions

Why should you convert PNG to BMP?

PNG files, while lossless, still use DEFLATE compression that some extremely specialized legacy systems cannot decompress. Vintage DOS applications, certain embedded systems, proprietary scientific equipment, and ancient Windows 3.x software predate PNG support (introduced 1996) and require raw uncompressed bitmap data. Converting PNG to BMP creates completely uncompressed raster data readable by virtually any system since the 1980s. However, file sizes explode dramatically - a 2MB PNG becomes 20-50MB+ as BMP. This conversion rarely makes practical sense in modern workflows - it's only necessary for: (1) compatibility with vintage DOS/Windows 3.x era software, (2) specialized industrial/medical equipment with hardcoded BMP requirements, or (3) preventing further processing in very specific archival scenarios. For almost all use cases, TIFF provides similar compatibility with better compression.
