are PDF files editable?
It’s difficult to edit PDF files very extensively. Adobe Acrobat has all kinds of tools to mark up PDFs and even do light editing. But the general point is true – Adobe Acrobat is not a word processor and PDFs aren’t meant to be edited directly.

* If a PDF created from a scanner or contains only pictures of the page – and at that moment, your computer has no knowledge of what’s on that page. You can’t edit that PDF in Word until OCR has been done.
do PDFs embed fonts?
We can embed the entire font, or just a subset of the characters used in the file. A font can be embedded only if it contains a setting by the font vendor that permits it to be embedded.
Embedding fonts in our PDF file allows anyone who opens our file to see the document as we intended. If we don’t embed a font, the PDF viewer will substitute a font if it is not available on the computer viewing the document, and the result usually isn’t what we intended.
can PDFs have hyperlinks?
Yes. When you create PDF documents, you might want to include a hyperlink to a Web page where readers can go to get more information on a subject. Merely typing the URL of the page into your document will not create a link in Adobe's products. Instead you use the link tool to create hyperlinks.
