Convert PNG to JXR

Looking for PNG 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 PNG 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 PNG to JPG, TIFF or WEBP instead.
