If you ever need to send a quick, short fax (three pages or less) faxZERO is a great solution that allows you to send them for free.
FaxZero is a Web based service that lets you send a fax to any fax machine in the United States (including Puerto Rico) or Canada, all you need is a valid e-mail address. You can also attach documents, a great application!
Great tip! Thanks Stephen
GotFreeFax.com also allows user to send free fax online to the US and Canada. User can either upload a PDF/Word file or enter text to fax. Plus, it does NOT add Ads to user’s fax and is suitable for faxing formal documents.
