Virtual fax, or ‘online/ internet fax’, is a form of document sharing that transmits files over the internet. While traditional faxing relies on transmitting documents fax-machine-to-fax-machine via ISDN and PSTN fax lines, virtual faxing shares documents between internet-connected devices. This flexibility means you can send and receive virtual faxes from your computer, smartphone or tablet.
Virtual faxing is often compared to email, though virtual faxing is more suited to document sharing. While most email providers transmit documents 10MG - 25MG, virtual faxing providers like eFax transmit files up to 3GB with Large File Transfer. Virtual faxing providers have also designed their systems to enhance the document sharing process. For example, eFax’s system allows you to sign your faxes with digital signatures, convert your file to a PDF, fax via email and save your faxes with cloud-based storage.
While virtual fax technology is popular among small and large businesses today, it’s been around for a long time. Virtual fax providers like eFax have been helping customers fax online since 1997. There are currently over 11 million customers worldwide using eFax, which transmits over 1 billion faxes per month.
