To send a fax over the eFax solution, users simply upload a document whether a PDF file or Word document to the eFax portal or mobile application and enter the fax number of the recipient.

The eFax solution transmits the document securely to the user’s email as a PDF file or Word document, often eliminating the need for a paper printout.

eFax enables users to digitally sign documents and fax them to other recipients. This helps organizations get documents such as contracts signed and finalized quickly and more efficiently.
