BMP to PNG
Convert Windows BMP images to lossless PNG at a fraction of the size. The conversion runs on your device.
BMP files are uncompressed and large, but converting them to JPG can blur sharp text and lines. BMP to PNG converts the image to PNG instead, which compresses it without losing a single pixel, so screenshots, diagrams and graphics stay exactly as they were in a much smaller file. The conversion happens inside your browser, so the image never leaves your device.
