I know this thread is quite old, but I am having trouble converting CMYK jpgs to RGB. Pressing "I" reveals that my images are CMYK jpgs and I would like to convert them to RGB. Image --> Change Color Depth is already set to 24 bits, hitting OK on that does not change the image being identified as CMYK.

How can I convert the image to RGB?

Thanks a lot in advance.

Ah, so it's implicitly converted to RGB and I just need to save/export?

Take for example this image:

In the browser, the background is a light blue (as here in this post), in XnView (which identifies it as JPEG CMYK) it is a bright torquoise.

So I think that some conversion is not right. Could that be?

My current workaround is to use Affinity Photo -> Document -> Convert Profile / ICC Profile... -> Colour Format: RGB/8, Profile: sRGB IEC61... and then export. When I then open it in XnView, it has the correct colors (as expected, because it was converted from CMYK to sRGB).
