About HDR to BMP
Convert HDR to BMP. HDR (Radiance RGBE) stores high-dynamic-range lighting with 32 bits per pixel. BMP is Windows' native raster format, commonly stored without compression. Uncompressed files run large; prefer PNG for the same pixels..
Why convert HDR to BMP?
- Larger files than lossy shares with BMP lossless or uncompressed quality.
- Keep quality where supported.
- Private, no upload - runs in your browser.
HDR vs BMP
| Animation | No | No |
|---|---|---|
| Transparency | No | Yes |
| Compression | lossless high dynamic range | lossless or uncompressed |
| Typical use | HDR (Radiance RGBE) stores high-dynamic-range lighting with 32 bits per pixel. | BMP is Windows' native raster format, commonly stored without compression. |
When not to convert HDR to BMP
- Skip BMP for the smallest share: lossless output stays large, so prefer a lossy target when sending HDR files.
- Keep a master copy: repeated exports stack small losses, so archive HDR before batch BMP shares.
Limits
Starting point: HDR - HDR (Radiance RGBE) stores high-dynamic-range lighting with 32 bits per pixel. Tone mapping compresses highlights into display range on export. Uncompressed files run large; prefer PNG for the same pixels. Export BMP from HDR at matched dimensions; every pixel maps across, so large sources stay large.
