There is a good tool that I found in internet and you can use as widget to increase your blog/site traffic. The tools offer you convert document to pdf. Yeah! For me it's awesome tools. You don't need adobe acrobat to convert document to PDF.
You can see this tool here
How about the result? The result is awesome too. You will not see any ads text on your converted document.
The other thing that I like with the tool is you can add this into your site as widget. So people can convert document on your site and the result will be send to their email.
