Making PDF Files Accessible
A Simple Test
Try to copy the text of your PDF file and paste it into a Word document. If it looks just like you see it in your PDF file, the document is fully accessible and you’re good to go.
- Accessible Sample (PDF, 12 pages)
It’s easy to select and copy the text from this PDF, and it looks exactly the same when pasted into Word.
- Inaccessible Sample A (PDF, 47 pages)
You can’t even select the text to copy it.
- Inaccessible Sample B (PDF, 48 pages)
You can copy the text—it’s been “captured” with optical character recognition (OCR), but if you try pasting it into Word you’ll see it’s not quite right; it hasn’t been proofread.
If Your Document is Not Accessible
OCR with Windows and Office (PDF) is a wonderful step-by-step guide (with pictures) to taking an inaccessible PDF file to a fully accessible text document using Acrobat Reader (the free PDF viewer) and Microsoft Office tools.
Users Don't Like PDFs
A great side effect of this procedure is that you'll have a plain text version of your document, ready to be republished in any other format, including as a plain ol' user-friendly and search engine optimized web page or site.

Acrobat Reader is a Vulnerable Application Targeted by Malicious Users
In 2011, a total of 35% of all exploit-related incidents targeted vulnerabilities in Adobe Acrobat Reader.
You can reduce your risk by using a less-targeted application like Nitro PDF Reader, but be aware that people who have heard that "PDF files are unsafe" may be wary of clicking on links to your PDFs.
