Researched and written by [Neeraja Prakash](https://research.g2.com/insights/author/neeraja-prakash)

Updated October 3, 2024

Online fax software enables users to securely send and receive faxes digitally. These platforms can transmit faxes through the software platform itself, by email, or from a platform’s mobile app, essentially turning a computer into a fax machine.

These tools save businesses the cost of paper, ink, and the machine itself. These solutions enable users to securely store documents as well as digitally sign and edit faxes, all without printing out documents. Online fax software platforms also remove hassles like a busy fax line. Additionally, a business has an existing fax number, they can transfer it to the fax software solution.

Online fax software performs the same functions as a fax machine, including the sending and receiving of faxes. These tools should not be confused with [email software](https://www.g2.com/categories/email). Online fax software sends electronic documents, typically in PDF format, directly to the recipient’s inbox via a fax number, while email software enables users to send electronic messages straight to the intended recipient’s inbox. While very similar, online fax is the preferred method for sending documents, specifically signed or confidential ones, as the transmission of information is typically more secure than email.

To qualify for inclusion in the Online Fax category, a product must:

- Allow users to send and receive a fax directly from the platform, an email account, or a mobile app
- Give users the ability to edit and sign documents within the tool
- Provide the ability to integrate with an existing fax number
