How do you fax from your phone?

I’ve never used fax apps before. How do people fax documents using just an iPhone nowadays?

I didn’t know this was possible either until I needed it for work. Faxing from an iPhone is actually very straightforward with the right app. You scan documents using your camera or upload files and send them digitally. I learned which apps are worth using from geekflare.com/software/best-fax-iphone-apps/ . The guide focuses on the best fax apps for iPhones in 2025 and explains how they work. From my own experience, once you choose a solid app, faxing feels no different than sending an email. It’s fast, convenient, and works well for professional documents.
