Our Methodology: How We Evaluated iPhone Fax Apps
Our editorial team evaluated over 15 iOS faxing applications on iPhone 15 Pro and iPhone 14 hardware running iOS 17 and iOS 18, across six criteria: transmission speed, edge-detection image quality, pricing transparency, App Store sentiment, compliance protocols (HIPAA, 256-bit AES encryption), and cloud synchronization.
Does Apple Have a Built-In Fax App?
Bottom Line Upfront: Apple does not provide a native fax application or built-in iOS feature for sending faxes directly from an iPhone.

While users can scan documents using the native Apple Files or Apple Notes app, transmitting scans to a legacy fax machine requires a third-party cloud gateway. Users can access web portals via Safari without installing apps; however, App Store solutions offer higher security, biometric authentication, and better camera adjustments.
