About this converter
BMP is the format of uncompressed bitmaps — huge files that many modern tools no longer accept. PNG is the safe universal replacement: lossless, supported everywhere, and usually smaller than the BMP it came from. This converter re-encodes your BMP files as PNGs locally in your browser, with nothing ever leaving your device.
