The folks over at FaxZero don’t think you should have to pay to send faxes, and offer free (ad supported) faxes from your computer in a one-page form. Faxes can be sent to any U.S. phone number (Puerto Rico included).

You can type in text to fax or you can attach a PDF file, Microsoft Word (.DOC) file, or Excel Spreadsheet (.XLS).

The free version of FaxZero has a two fax per day limitation. You can also pay $1.99 per fax that doesn’t have any ads on the cover page if you wish.

Especially useful if you still deal with industries that rely on faxes, these online fax services can help you save on fax paper, fax machine upkeep and keep digital copies of all your fax communications.
