Convert HDR to JXR

Looking for HDR to JXR? Here's why JXR isn't an output option — and the modern formats to use.

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.

2

Convert to a current format

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