PNG offers significantly better compression than BMP while maintaining the same lossless quality. You'll get files that are 50-75% smaller than BMP, making them easier to store, share, and use on websites. PNG also adds transparency support that BMP lacks.
No! Both BMP and PNG can store images losslessly. The conversion maintains pixel-perfect quality - every detail is preserved exactly. PNG just compresses the data more efficiently, resulting in smaller files without any quality loss.
PNG files are typically 50-75% smaller than equivalent BMP files. A 10MB BMP might become a 2-3MB PNG. The exact reduction depends on image content - simple images compress more, detailed photos compress less.
For most uses, yes. PNG is superior to BMP in almost every way - smaller files, transparency support, and universal compatibility. Keep BMP only if you're working with specific legacy software that requires it.
Yes, and more! PNG supports everything BMP does (lossless RGB and grayscale images) plus transparency/alpha channel which BMP doesn't have. PNG is a better format in practically every scenario.
