What happens when you convert HDR to JPEG?
Quality
Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG. Quality defaults to 82; adjust it in Advanced options. File size depends on the image and encoder.

A familiar format for photographs. JPEG keeps files compact by trading a little image detail for broad compatibility.

Good choice when
- JPEG fits your delivery use: Photographs & sharing.
- You need an SDR delivery copy and can review its tone mapping.
- You accept lossy encoding for photographic delivery.
- You can validate the destination’s sample precision and colour interpretation.
Probably not when
- You need the original HDR range for relighting or grading.
- You need an exact pixel reference or repeated lossless editing.
- You require identical samples without a defined colour and precision policy.
HDR to JPEG conversion details
- HDR to SDR
- HDR is rendered to SDR using exposure and Reinhard tone mapping.
- Quality
- Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG. Quality defaults to 82; adjust it in Advanced options. File size depends on the image and encoder.
- Sample precision & colour
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- Metadata & colour
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- Compression
- HDR: Lossless → JPEG: Lossy HDR: RLE preserves stored RGBE bytes; RGBE quantization is not exact storage of arbitrary float RGB. The .hdr format is distinct from the general concept of HDR photography. JPEG: Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG.
- Colour depth
- HDR: 32-bit RGBE / XYZE pixel
- HDR
- HDR: Radiometric values
- Dimensions
- Rendered image dimensions are retained within the converter limits; this tool does not offer resizing. Orientation handling depends on the source decoder.
- Metadata
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Common questions
How will HDR brightness be mapped?
HDR is rendered to SDR using exposure and Reinhard tone mapping.
Can converting HDR to JPEG reduce quality?
Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG. Quality defaults to 82; adjust it in Advanced options. File size depends on the image and encoder.
Are bit depth and colour values guaranteed to match?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Will metadata and colour profiles be retained?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
