How to Send an Encrypted Fax from iPhone
You can send an encrypted fax from iPhone without any hardware or complicated setup — just an app and a document.
Faxend protects every fax with AES-256 encryption in transit and at rest, so sensitive documents like medical records or legal filings stay private from the moment you hit send.

Why encryption matters for faxing
Traditional fax machines send data over analog phone lines with no encryption at all. Anyone with access to the telephone network can intercept a plain-text fax. That is a serious problem for medical offices, law firms, and financial advisors who fax sensitive information daily.
Online fax services solve this by wrapping your document in encryption before it ever leaves your phone. The fax travels over secured internet protocols instead of an open analog line. The difference is significant.
Under HIPAA, covered entities must protect electronic protected health information (ePHI) in transit. Sending an unencrypted fax of a patient record is a potential violation. Using an encrypted fax service is one of the simplest ways to close that gap.
Even outside healthcare, encryption protects attorney-client privilege, financial records, and personally identifiable information. Its good practice regardless of industry.
What you need before you start
You do not need a fax machine, a phone line, or a scanner. Here is what you actually need.
- An iPhone running iOS 16 or later
- The Faxend app from the App Store
- The document you want to fax (PDF, photo, or Word file)
- The recipient's fax number, including country code for international faxes
- A Faxend account or a one-time Basic credit if you only need a few pages
That is genuinely it. No additional hardware required. If you already use the iPhone Files app or have documents saved to iCloud Drive, you are ready to go right now.
Step-by-step: send an encrypted fax from iPhone
Open the App Store and search for Faxend, or tap the direct link above. Install it like any other app. If you prefer the browser, go to faxend.com/send on Safari instead.
Create a free account for Standard or Pro features. For a quick single fax, the Basic plan at $2.99 lets you send up to 5 pages with no account required. Choose what fits your situation.
Type the full fax number including the country code. For US numbers, that means a 1 followed by the area code and number. Faxend supports 120+ countries via the Sinch backbone, so international faxes work the same way.
Tap the attachment icon and choose your file from Photos, Files, or iCloud Drive. Faxend accepts PDFs, JPEGs, PNGs, and common Word formats. The app converts everything automatically before sending.
Preview the fax to confirm page order and content. When you are satisfied, tap Send. Faxend encrypts the document with AES-256 the moment it leaves your device. A typical single-page fax arrives at the recipient in 30 to 60 seconds.
Standard and Pro accounts show a full delivery history inside the app. Basic users receive an email confirmation. Either way, you know whether the fax reached its destination.
The whole process takes about two minutes once you have the app installed. For more detail on the iPhone-specific workflow, see our guide on how to send a fax from iPhone.

HIPAA compliance and the BAA
Encryption is one piece of HIPAA compliance. The other critical piece is a signed Business Associate Agreement (BAA).
Under HIPAA, any vendor that handles ePHI on your behalf is a business associate. You need a written BAA with them before sharing patient data. Without one, your organization carries the full liability for any breach involving that vendor.
Faxend offers a BAA on every plan, including the $2.99 Basic tier. That is unusual. Most competitors restrict BAAs to higher-priced business plans. If you are a solo practitioner or small clinic watching costs, this matters.
A BAA does not replace good security practices. It establishes shared accountability. Encryption handles the technical side; the BAA handles the legal side. You need both.
The HHS Security Rule provides the full technical safeguard requirements if you want to go deeper. For most small practices, using an encrypted fax service with a BAA is the practical starting point.

Choosing the right Faxend plan
Faxend has three plans. The right one depends on how often you fax.
| Plan | Price | Pages | HIPAA / BAA | Inbound Number | History |
|---|---|---|---|---|---|
| Basic | $2.99 one-time | 5 pages, 30-day credit | Yes | No | No |
| Standard | $9.99/month | 20 pages/month | Yes | No | Yes |
| Pro | $19.99/month | Unlimited | Yes | Yes (dedicated) | Yes + priority delivery |
Basic is ideal for occasional faxing, like a one-time tax document or a single insurance form. Standard suits small offices sending a handful of faxes per week. Pro is the choice for high-volume users who also need a dedicated inbound fax number.

How Faxend's encryption actually works
AES-256 is the encryption standard used by the US government for classified information. It is the same algorithm banks use for online transactions. Breaking it with current computing power is not realistically possible.
Faxend applies AES-256 at two points. First, in transit: the document is encrypted as it travels from your iPhone to Faxend's servers and onward to the recipient. Second, at rest: if your document is stored (for history on Standard and Pro plans), it stays encrypted on the server.
The fax is transmitted over the T.38 protocol, which is the internet standard for fax over IP. Faxend's infrastructure runs on the Sinch network, which handles carrier-grade fax delivery across more than 120 countries.
One thing worth understanding: encryption protects the document in transit and storage. It does not control what the recipient does with the printed fax on their end. Physical security at the destination is still the recipient's responsibility. That is true of every fax service, encrypted or not.

Frequently asked questions
Is faxing from iPhone actually secure?
Yes, when you use an encrypted fax service. Faxend applies AES-256 encryption both in transit and at rest, so your document is protected from your iPhone to the recipient's fax machine. Traditional fax machines offer no encryption at all.
Does Faxend meet HIPAA requirements for faxing?
Faxend is HIPAA-ready on every plan and offers a Business Associate Agreement (BAA). You still need to sign the BAA before faxing protected health information. The BAA is available on Basic, Standard, and Pro tiers.
Can I send an encrypted fax without creating an account?
Yes. The Basic plan at $2.99 lets you send up to 5 pages with no account required. Encryption and HIPAA compliance still apply. You will receive delivery confirmation by email.
What file types can I fax from my iPhone?
Faxend accepts PDFs, JPEGs, PNGs, and common Word document formats. The app converts your file automatically before sending, so you do not need to convert it yourself.
How fast does an encrypted fax arrive?
A typical single-page fax arrives in 30 to 60 seconds. Pro plan users get priority delivery, which can be faster during high-traffic periods. Multi-page documents take a little longer.
Does encryption slow down fax delivery?
No noticeable difference. The encryption and decryption process happens in milliseconds on modern infrastructure. Delivery time depends on the recipient's fax line, not the encryption step.
Send your first fax in 60 seconds
No fax machine. No subscription required. Pay $2.99 for up to 5 pages and own your sending without monthly lock-in.
