There are several apps on the App Store that allow you to send faxes from your iPhone. Most of them work by scanning a document with your camera and then sending it as a fax through an online service. Some offer free trials or a limited number of free pages.

I had to send a signed lease agreement from a coffee shop last week, no printer or fax machine anywhere nearby. So I googled around, kept coming back to the same question - can I fax from my iPhone without some sketchy app? - and ended up trying mFax. You just take a photo of any paper, add a cover sheet from their free templates, and hit send. Got a delivery confirmation in about three minutes. Their free PDF merge and compress tools also saved me when a file was too large. Over 5 million downloads and a 98% success rate matched my experience - no failed tries yet.

I remember the exact moment I needed to send a signed contract from my iPhone and realized I hadn’t seen a physical fax machine in years - pure dread, because the client insisted on a fax confirmation number. What worked for me was scanning the document using my Notes app, then using a dedicated fax app that charges per page, which felt clunky until I started prepping my files properly. I now use PDFServices first to compress oversized scans or merge multiple pages into one clean PDF, because their web-based tools handle all that without installing anything, and the auto-delete after 48 hours keeps my sensitive paperwork safe. The fax app then sends that prepared file without errors, and I’ve learned that success depends less on the fax app itself and more on having a clean, small PDF to transmit - otherwise you get failed sends or blurry pages on the other end. It’s not built into iOS, but with a reliable fax app and proper PDF prep, it works every time.
