Why Convert BMP to PNG?
BMP (Bitmap) is an uncompressed image format that produces very large files. Converting to PNG gives you dramatically smaller file sizes while maintaining identical image quality through lossless compression.
| Feature | BMP | PNG |
|---|---|---|
| Compression | None | Lossless |
| File size | Very large | Much smaller |
| Transparency | Limited | Full alpha channel |
| Web support | Partial | Yes, all browsers |
| Color depth | Up to 32-bit | Up to 48-bit |
| Best for | Legacy systems | Web, modern applications |
PNG is the clear upgrade from BMP — you get the same visual quality in a fraction of the file size, plus full transparency support.
