View and notate faxes anywhere. Sfax mobile viewer is now available.

Sfax is the only cloud fax service designed for the rigors of healthcare and other industries that demand business-critical services. Sfax viewer allows you to view, make notes, delete and move your documents securely.

We initially built the Sfax app to support the launch of our Sfax v3 product back in 2013. In line with the new Sfax branding, we decided to redesign and rebuild the app from the ground up starting with this Sfax Viewer. This new version has improved viewer quality and the pinch and zoom functionality.

The viewer also allows notes to be attached to documents, which will appear in an audit trail for increased HIPAA compliance. In order to maintain this compliance, users will not be able to download files to your device. Instead you are getting a new UI with improved performance, stability and security. More updates will be added in the coming months with plans to add forward, reply and send functionality soon.

You must be an existing Sfax customer to use the Sfax mobile viewer.
