Saving something as a PDF file is a great way to preserve it for future reference or for sharing with others, without risking the site changing before you look at it again. PDFMyURL makes it easy to convert sites to PDF.
Point 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. Have a favourite tool for PDF conversion or a bookmarklet that makes life easier? Let's hear about it in the comments.
