i was just wondering if anyone can get me in the right direction of editing a pdf file! this file is a brochure for my friends company and he was wondering if i can do some editing and redesigning on it!

what is a recommendation on a pdf editor and does these editors do redesigning or picture insertions and stuff? can i design this on other programs like photoshop or fireworks and convert it to a pdf file?

cheers guys

Yes you can open and edit pdf's in photoshop. Photoshop pdf
Otherwise you need to buy either Adobe writer or something like PDF Edit
