I’ve shared free, portable PDF reader and adobe reader alternatives, but most need to be either installed or require downloads.

Incase you need a PDF Reader instantly and don’t have installed you can tryout PDFmeNot, a online PDF Reader.

It’s simple to use PDFMeNot, It supports either a file upload or hyperlink to the PDF  .

• Visit PDFMeNot and Enter the URL of a PDF file ( OR )
• You can also upload an local file from your system.

The uploaded PDF file is then converted to a Flash document with zooming capabilities.An embed code is also available for embedding the PDF elsewhere online.

This can be really useful when pointing to a PDF file to someone who might or might not have a PDF reader installed.

PDFMeNot is also providing 5 Tools for easier access to its service

• Linking to the file directly

For Example : http://test.com/document.pdf

Use this link instead: http://pdfmenot.com/view/http://test.com/document.pdf

• Bookmarklet – Convert all pdf links on a page to use PdfMeNot.Visit here for the Bookmarklet Code
• Firefox Extension – Will automagically fix links to pdfs as your browse.Install the Extension from here.
• Webmaster/Blogger Script – Webmasters/bloggers can automatically convert any pdfs they link to.

Placing this inside the </head> tag.

<script type="text/javascript" src="http://pdfmenot.com/convert.js"></script>

• Embed Code – Place a pdf viewer inline within your pages using the following code

<script type="text/javascript" src="http://pdfmenot.com/embed/?url=http://test.com/document.pdf
