Looking for a tool (very low price or free) which will convert cmyk pdf's to rgb pdf's.  Reason: I using Paintshop Pro instead of photoship because it's much cheeper.  However, Jasc PSP doesn't  open cmyk pdf's correclty - it tints the colours slightly.  

Alternatively I'll settle for a way to fix the colours in PSP.

Remember that there is not a direct 1 to 1 translation from RGB to CMYK colorspaces, which is why both are still in regular use. Here's some good background on the process: http://digitaldog.imagingrevue.com/files/RGBtoCMYKconversons.pdf

I would take a look at The Gimp (http://www.gimp.org) It rivals photoshop in power, and will open PDFs. Unfortunately, it does not have good CMYK support, but while you have to have a plug in to go from RGB -> CMYK, it may well open and convert CMYK to RBG without trouble. And it's free.

If that does not work, the next cheapest way that I know will do the conversions you want is Jaws PDF Creator (http://www.jawspdf.com). I am not sure if the Jaws PDF Editor will do it (it's cheaper), but you might check with them and see.

Thanks for the background info.

Jaws Editor won't do it without creator, but reasonable price.
