Frequently Asked Questions
What is a BMP file?
BMP (Bitmap) is an uncompressed image format from Microsoft. It stores raw pixel data, resulting in large file sizes but no compression artifacts.
Why convert BMP to PNG?
PNG offers lossless compression (smaller files), transparency support, and universal compatibility. BMP files are often 10-20x larger than equivalent PNGs.
Is quality preserved?
Yes, the conversion is completely lossless. PNG compression doesn't reduce image quality at all.
What about 32-bit BMP with alpha?
Some BMP files include alpha transparency. This tool preserves that transparency when converting to PNG.
