We rarely run into situations where we absolutely have to send a fax these days. Most of the time, a PDF will do. But if you need to send a document to someone whose only means of communication with the outside world is a fax machine, you can still sign and send the contract necessary to help that nice Nigerian fellow's funds out of the bank account they're stuck in.

Drop.io is a file sharing service that we've covered in the past. The service provides you with a unique URL that you can share with friends and colleagues so that anyone can upload and share documents. Drop.io recently added the ability to send uploaded documents via fax. You can send Word, Excel, and PDF files to any fax number. The only limitation is that files cannot be more than 20 pages long, which is a vast improvement over other free online fax services like FaxZero, which will charge $1.99 per page for any document longer than three pages.

Best of all, you don't even need to sign up for a drop.io account to send a fax. Just visit the main page, upload your document, and click send on the subsequent page.
