Frequently Asked Questions
Is PNG always smaller than BMP?
Yes, significantly. PNG lossless compression is far more efficient than BMP's uncompressed storage, especially for graphics with flat colours.
Can PNG files replace BMP everywhere?
For most use cases, yes. PNG is supported by all modern operating systems, browsers, and design tools that also read BMP.
Does BMP have transparency?
Standard BMP files do not support transparency. The PNG output will have a solid background matching the BMP.
