Reasons to switch from HDR to BMP
- No compression artefacts
- Very simple to read
- Supported by every Windows program
- Works with: Windows, macOS, Linux and most image editors
What to expect from this conversion
- Both formats store the pixels without loss, so the picture stays identical. Only the file size and compatibility change.
- HDR holds values brighter than a normal screen can show, so the image is clipped to the displayable range and converted to sRGB. Very bright highlights lose their extra range.

Tips for the best result
- Use quality 80 to 90 for photos: it is visually close to the original at a much smaller size.
- Set a width if the image will be shown on a small screen, which also reduces the file size.
- Choose a background colour before converting transparent images to a format without transparency.
