What's a good PDF editor for Mac OS X?

i use graphic converter

pages?

btw, graphic converter is from lemkesoft.com. very simple to use. never tried using pages to open and edit a pdf, maybe it is possible.

never thought to try pages, thanks

neooffice can also export as pdf, so you could always copy text into neooffice, then export.

If you want a free online PDF editor (Safari & Firefox compatible):

Or:

(to convert a PDF to a doc file online, and then open it with Word or Pages)

I don’t know of any free tool but there is a commercial tool called PDF Studio:

You can use this to annotate / review PDF documents as well as fill-in forms. Even if the forms are not fillable you can use a typewriter annotation that allows to add text anywhere in a document.
