Another cool site pointed out by LifeHacker today. We've got CometDocs. This site will allow you to upload a document in just about any format and convert it to just about any format. Once you upload the document you want to convert and pick the format you want to convert it to it will email a link for you to download the converted document from. It took about 5 minutes after I submitted my conversion (The Lotus Domino 7 Development redbook) to receive the email. Pretty cool!
Cometdocs is a one of its kinds free online document conversion interface that offers a large set of document conversions that can't be found anywhere else online. Its unique features include on the fly OCR conversion capabilities, over 50 different conversion options and proprietary XPS and PDF conversion abilities that retains formatting, images and text in the selected output format. And best of all for users -> it is available free of charge.
