What happens when you convert HDR to JPEG 2000?
Transparency
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
Encoding mode
JPEG 2000 supports reversible lossless and irreversible lossy coding. A JP2 container, an extended JPX/JPF file and a raw J2K codestream are related but not identical file structures. The output uses the implemented still-image encoder; file size depends on the pixels and format.

Good choice when
- JPEG 2000 fits your delivery use: Specialised scalable imaging.
- You need an SDR delivery copy and can review its tone mapping.
- Your receiving application supports the required JPEG 2000 variant.
- You can validate the destination’s sample precision and colour interpretation.
- You need a JPEG 2000-compatible workflow that can hold transparency added in a separate edit.
Probably not when
- You need the original HDR range for relighting or grading.
- You need a guaranteed output file size or archival pixel equality. Encoder settings do not guarantee either.
- You require identical samples without a defined colour and precision policy.
- You expect automatic background removal or transparency.
HDR to JPEG 2000 conversion details
- HDR to SDR
- HDR is rendered to SDR using exposure and Reinhard tone mapping.
- Transparency
- The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
- Encoding mode
- JPEG 2000 supports reversible lossless and irreversible lossy coding. A JP2 container, an extended JPX/JPF file and a raw J2K codestream are related but not identical file structures. The output uses the implemented still-image encoder; file size depends on the pixels and format.
- 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 2000: Lossy & lossless 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 2000: JPEG 2000 supports reversible lossless and irreversible lossy coding. A JP2 container, an extended JPX/JPF file and a raw J2K codestream are related but not identical file structures.
- Transparency
- Transparency is replaced with white by default. Change the background in Advanced options.
- Colour depth
- HDR: 32-bit RGBE / XYZE pixel → JPEG 2000: Component-defined precision
- 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.
Will the background become transparent?
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
Which compression mode will JPEG 2000 use?
JPEG 2000 supports reversible lossless and irreversible lossy coding. A JP2 container, an extended JPX/JPF file and a raw J2K codestream are related but not identical file structures. The output uses the implemented still-image encoder; file size depends on the pixels and format.
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.
