Why convert PNG to BMP?
PNG is a lossless format that keeps every pixel intact and supports a full alpha (transparency) channel. Files are larger than JPG but quality never degrades. BMP is an uncompressed raster format from early Windows. It preserves every pixel but produces very large files, so it is mainly used for compatibility with legacy software.
- BMP has no transparency channel, so any transparent areas are flattened onto a solid background (white by default, adjustable below).
- Improve compatibility — BMP is widely supported and easy to use across the apps and platforms you rely on.
