Converting an RGB jpeg to CMYK?

[MickeyFinns]

I've been looking around for a way to turn a RGB jpg into CMYK and am having no luck.

Does anyone have a solution?

Thanks

Imagemagick?

Will give that a try tonight, thanks.

I can do it for you if its a one-off?

Nah that's fine, there 3 graphics in this batch and potentially a lot more. Thanks anyway.
