Bitmap (BMP) is an uncompressed legacy format from the early days of Windows. It takes up unnecessary space. Convert to PNG to get the exact same image quality at a fraction of the file size.
BMP vs PNG
| Feature | BMP | PNG |
|---|---|---|
| Compression | None | Lossless |
| Transparency | No | Yes |
There is essentially no reason to use BMP in the 21st century. PNG does everything BMP does (lossless, pixel-perfect) but adds compression and transparency support.
BMP stores color data literally bit-by-bit. PNG uses compression algorithms to store patterns, resulting in much smaller files for the same data.
Frequently Asked Questions
Why convert BMP to PNG?
BMP files are uncompressed and take up unnecessary space. PNGs are lossless but compressed, saving disk space without losing quality.
Does PNG support transparency?
Yes, PNG supports full alpha transparency, which BMP does not always handle well.
