Using Image and File Attachments « WordPress Codex

This isn’t the easiest to read set of instructions – but it’s the best that’s out there for now.

If you want to attach a Microsoft Word doc (not recommended) or a PDF (recommended) to your WordPress blog- these are the steps.

• The reasons you don’t want to attach a Word Doc:
• not everyone has Word
• Word can contain viruses
• Word formatting will break depending on fonts and computer platform.

But- if you load a PDF:

• Everyone can read it with the free Acrobat reader
• Search engines will parse it
• Many people can read the PDF within their browser
• It will look exactly the same on every machine
• It can have fields in it to fill out on the computer

I hope to put a simple step-by-step how to upload PDF’s to your WordPress blog soon. For now- the codex link at top is the best I could find.
