HDR to JXR

Looking to convert HDR to JXR? Here's the honest answer — and what works instead.

We don't create JXR files — it's a legacy format that's effectively read-only. Here's what to convert to instead.

Why HDR to JXR isn't offered

1

JXR is legacy and read-only here

JXR (JPEG XR) is a Microsoft high-dynamic-range format with little support outside Windows. It can usually be opened and converted from, but it's long obsolete, so there's no modern encoder to create new JXR files.

Convert to a current format

For a file that opens everywhere, convert your HDR to PNG, JPG or TIFF instead.
