Frequently Asked Questions
Does iPhone have a built-in fax feature?
No. iOS does not include a native fax app. To use fax on your iPhone, you need a third-party online fax service like mFax.to — accessible via Safari or their free app, with no hardware required.
How do I enable fax on my iPhone?
There is nothing to "enable" — iOS has no fax setting. Sign up for an online fax service like mFax.to, then open it in Safari or download their app. You can start sending faxes in under 2 minutes.
Can I send a fax from my iPhone for free?
Yes, with limitations. mFax.to uses a pay-per-use model so you only pay when you actually send — no monthly subscription required. Some services also offer a limited free tier for occasional senders.
Can I receive faxes on my iPhone?
Yes. Any online fax service that gives you a dedicated fax number delivers incoming faxes as PDFs to your app inbox or email. You get a push notification the moment a new fax arrives.
What is the best fax app for iPhone?
mFax is consistently rated among the best iPhone fax apps, with a 4.8 App Store rating and over 5 million users. It supports both sending and receiving, includes HIPAA-compliant options for healthcare users, and works in Safari too — no download required.
