Convert PNG to BMP online
Use this PNG to BMP converter to turn PNG files into BMP right in your browser — ideal for uncompressed raster images and legacy Windows graphics. PNG supports transparency while BMP does not, so transparent areas become a solid background color.
When should you convert PNG to BMP?
- When you don't need a transparent background
- When you need it for uncompressed raster images
- When you need it for legacy Windows graphics
- To open your files in apps that prefer BMP
What happens to your file
BMP cannot store transparency, so any RGBA, LA, or palette image is composited onto a solid white background first and then saved as RGB.
Settings this conversion runs with
| Engine | Pillow (Python Imaging Library) |
|---|---|
| Colour mode | RGB |
| Alpha channel | Flattened onto white |
What changes
- Your PNG can hold transparency and BMP cannot. Transparent pixels become white — not "removed", but painted over. If you need the cutout to survive, stay on PNG, WebP, or AVIF.
