Convet CMYK to RGB

[marc_dantinne]

Dear,
I'm currently looking for "how to convert" a file in CMYK to RGB? I'm unable to find this option in Irfanview 4.10

Thans in advance for your help

I'm unable too.
I found an online converter for this here.
And some warning about this process :
~
RGB has less degrees of freedom (3) than CMYK (4).
Therefore, although one can convert any RGB to CMYK without losing information, the inverse is not the case.
When a CMYK color is converted to RGB, some information is lost.

If Irfanview is able to load the file then it will be converted to RGB in memory.
All depends on the file format.
