This application just easy the task of converting a PDF file to images + an HTML page that you can view in the 3DS browser.
If you have an Dropbox account and its Windows client installed, viewing a PDF in your 3DS is just a matter of dragging the PDF into the program, and then it will create a .html page, put it in your Dropbox public folder, grab the public URL, and optionally get a Bitly shorted link. So you get the URL, put it in your 3DS browser, and you can now view the PDF rendered as image files.
Requirements:
-Windows 7 or later, and probably Vista (not tested)
-Dropbox client (optional)
Download v2.1
Any suggestion or criticizes are welcome =D
