Weird Adobe JPEG CMYK images?

[Unipaasi]

I have a long list of some kind of Adobe JPEG CMYK files. Problem with these is that file sizes are very big and i can't figure out how to fix that.

Example file can be found here:

Quality is 86. I have tried to -colorspace RGB, but it doesn't seem to fix size problem.

Any ideas?

-strip will remove profiles etc:

Code: Select all

convert 710006.jpg -strip -quality 50 x.jpg

Adjust quality parameter to suit.

Thanks Snibgo! You saved my day.

Code: Select all

mogrify -strip *.jpg

Pleasure. Of course, blindly stripping out the profile does change the colour slightly.
