About Radiance HDR
High dynamic range image format.
About JPEG image
Very small files for photographs, universal application support, and an adjustable quality setting. Lossy compression can create block and ringing artifacts; it has no alpha transparency and is poor for sharp line art or screenshots.
Format referenceWhy convert HDR to JPG?
- JPG is more appropriate for the target application, device, or delivery channel than HDR.
- Compatibility is the main reason to convert when another person or service cannot open the source.
- The new format may support a feature the source container does not.
- The result can be reviewed without changing the file that other people still use.
Will quality change?
The destination uses lossy image compression, so repeated conversions can add artifacts. Start from the best source available and review the result at its final size. Keep the source if you may need to adjust the conversion later.

When not to convert
