How to Send a Fax From an iPhone
An iPhone has no built-in fax function and never has — iOS has no modem and no Fax app in the App Store from Apple. What it does have is a scanner hidden inside the Notes and Files apps, a Photos library full of documents, and a browser that uploads any of those to an online fax service. That combination lets you turn a paper form on your desk into a delivered fax in about a minute without touching a fax machine.
Can an iPhone send a fax on its own?
No. The iPhone has no fax hardware, so there is nothing to dial a fax tone with. The workaround people reach for — screenshotting and emailing — does not reach a fax line, because a fax number answers with a modem, not an inbox. The reliable path is to capture the document as a PDF on the phone and send it through an online fax service that bridges to the recipient's fax machine over the phone network for you.
How to send a fax from your iPhone
- 1Open Notes, tap the camera icon, and choose Scan Documents to photograph each page — the scanner auto-crops the edges and flattens the page into a clean PDF (or open a PDF you already have in the Files app).
- 2Sign up for Send FAX Mail in Safari and start the 7-day trial; verify your email so sending is unlocked.
- 3In Send FAX Mail, tap the upload button and choose your scanned PDF straight from the Files or Photos app.
- 4Enter the recipient's fax number, including the country and area code, in the To field.
- 5Add an optional cover page with a note, then tap Send.
- 6Wait for the delivery confirmation email — it records the exact time the receiving fax line answered.
Before you send
Scan in good light so small print stays legible after the page is compressed — a faint prescription or account number is the most common reason a fax gets rejected. PDF is the ideal format because it keeps the page at a fixed size; a raw Photos image works too but may need cropping first. If a form runs several pages, scan them into a single PDF rather than sending each page as its own fax so they arrive stapled together.
Send a fax from iPhone — FAQ
Apple has never shipped one, and iOS gives third-party apps no access to a fax modem, so any App Store listing that promises native faxing is actually routing your document through an online service in the background. Sending from Safari through Send FAX Mail does the same job without installing anything, and you keep the confirmation in your email.
Yes. In Send FAX Mail, upload the picture straight from your Photos library and it is converted to a letter-sized page before it goes out. For a multi-page contract, though, the Notes scanner produces a cleaner result because it squares up each page and removes the shadows a casual photo leaves behind.
Either one is fine. The fax itself travels over the phone network on our servers, so your iPhone only needs enough of an internet connection to upload the PDF. A single-page document is a small upload that goes through comfortably on cellular.
The 7-day trial covers a first send at no charge and asks for no card to begin, which is enough for a one-off form. If you fax regularly, the Starter plan is $12.99/month and covers 600 pages; reaching that allowance prompts an upgrade rather than a per-page charge.
