“New in Word 2013, you can edit .pdf files. Earlier versions of Word let you save a document as a .pdf, but you couldn’t edit a document in that format — you’d have to convert it to a .docx or .doc file first. Now, when you open a .pdf with Word 2013, you can read the file, edit it, and save it as a .pdf — no conversion needed. No more worries about tables or other elements getting messed up by switching formats.”
