If the pdf is a text document, you can probably convert it to pretty much any format you want. If it's a scan of a document or a fax, you might have to get some OCR-foo going.
Another thing to think about is that Spanish really isn't all that far from Latin (with a few Arabic words thrown in, but those are easy: pretty much anything in "al-" is of Arabic origin) and English has a lot of Latin words in it. Oh and try to remember that embarazada does not mean "embarrassed".
