Combine PDF Files, Convert Web Page URLs to PDFs on the fly
LOOP is a unique extension for Firefox that converts the web browser into a proper PDF writer that can do some amazing things sometime not possible in other free PDF conversion software.
First and foremost, as you are browsing the web, click the Add URL button and that webpage will be converted to PDF almost immediately - the entire process requires a single click. You can continue browsing and keep adding more URLs to the PDF queue - all the PDF conversions will happen in the background with interrupting your work.

If you have any local documents (like Word, Powerpoint, Excel or Images), LOOP for Firefox will convert those as well to PDF files - click the "add file" button.
And finally, there's a "Combine All" button which will merge all the PDFs that you added to the queue and will create one PDF file out of them. You can also reorder the pages in the Combined PDF with the "move up" or "move down" buttons.
Pretty innovative and useful extension. Requires you to create a quick account on Drawloop website. The pro version offers password protected PDFs.

Very interesting plugin! I'm sure many people will find it helpful. At least, It will help me in my future project!
This is an awesome plug-in...thanks for sharing Amit!
By "pro version" Amit is referring to the "advanced" button on the add-on that opens a new tab in Firefox and directs it to the Advanced Page Order section of LOOP. There you can rearrange individual pages, add bookmarks, and add security. The Advanced Page Order is also free and available to any registered LOOP user.

Dear Amit,
many of your technology posts are so useful and simple to follow with all needed links to install and understand about new software, that I now really first like to search my reader or your web site first for answers to my technology related questions.
and I would consider googling after learning from your posts. Many a times I am spared fo googling for my question as I get all needed info from your posts itself and I do not need to google then. Thanks a lot.
