Why Convert BMP to PNG?

BMP files come mostly from older Windows programs, scanners, and screenshot tools, and they are huge because the format applies no compression at all. PNG stores the identical pixels losslessly while typically cutting the file size dramatically, and it is understood by every modern browser, editor, and operating system. Converting BMP to PNG loses nothing - same pixels, much smaller file - and the conversion never leaves your device.

Lossless Compression

PNG keeps every pixel of your bitmap intact while cutting the file size dramatically.

Modern Compatibility

PNG is supported by every browser and app, unlike BMPs from legacy Windows software.
