PDFMyURL at a website URL and it will convert the site into a PDF document. Not only can you do a simple conversion just by plugging in a URL but you can also modify the PDF with a wide variety of flags—see the advanced menu for a full list—that let you set the page orientation and size, header information, print orientation, and more. PDFMyURL also has a bookmarklet you can drag to your toolbar for easy access to the PDF creation service.
PDFMyURL is a free service and doesn’t watermark or otherwise alter the site you are converting to PDF.
Let the words roll off your mind!
