According to the Environmental Protection Agency, the U.S. population consumes more than 4 million tons of paper each year. The average U.S. office worker uses about 10,000 sheets of copy paper every year. San Francisco based start-up HelloFax is built on the simple premise that most faxing is done to transmit signatures. Therefore, it allows you to download documents, sign, initial, or fill-in information on the document in your browser before sending to your recipient. With no sign-up fees, contracts, or subscriptions needed, it is built for both heavy and infrequent fax users with various pricing plans.

COST: Free to $39.99 per month, based on number of faxes sent.
