Convert HDR photo (.JXL) to PNG

[prozender]

Hello, anyone know how to convert HDR photo (.JXL) to PNG?

Hello, I don't think there are tools that can do that, yet. But if you make a HDR screenshot with Action! you will see it creates three files: raw data, HDR (jxl) and SDR (png/jpg/bmp).

That's too bad, was hoping there was a way, my problem is that steam screen captures suck while Win10 Screenshot (winkey+PrntScr) actually takes an HDR screencap but is often overexpose. The .JXL file I'm getting from Action reccorder is the most accurate image yet so I was hoping to convert that to JPG and upload that on steam, etc

You can use the jpeg/png file created with Action!. HDR content cannot be save in jpeg/png, only in jxl.
