Best Mobile Fax App in 2026 (iPhone & Android)

What to look for in a mobile fax app

Not all fax apps are equal. Some charge monthly fees even if you send one fax a year. Others bury HIPAA compliance behind enterprise tiers.

Before picking an app, get clear on a few things. How often will you actually send faxes? Do you need a dedicated inbound number? Is HIPAA compliance required for your work?

Speed matters too. A fax that takes 10 minutes to deliver is frustrating when a single page should arrive in under a minute on a modern service. T.38 fax-over-IP protocol is what separates fast, reliable delivery from the older analog-emulation approach.

Security is non-negotiable for medical, legal, and financial documents. Look for AES-256 encryption both in transit and at rest. If you work in healthcare, confirm the provider will sign a Business Associate Agreement before you send a single protected health record.

Finally, check the pricing model honestly. A $10/month plan sounds cheap until you realise you only send two faxes a month.

Top mobile fax apps compared

Faxend

Faxend runs on iPhone via the App Store and on any device through faxend.com/send. Its pricing is unusually honest. The Basic plan is a one-time $2.99 payment for 5 pages with no account required. That alone sets it apart from every subscription-first competitor.

The Standard plan ($9.99/month) adds 20 pages, fax history, and HIPAA compliance. The Pro plan ($19.99/month) gives you unlimited pages, a dedicated inbound fax number, and priority delivery. AES-256 encryption covers every plan, not just the top tier.

Delivery is fast. A single page typically arrives in 30 to 60 seconds. International sending covers 120+ countries through the Sinch backbone.

The main limitation: the dedicated inbound number is Pro-only. If you need to receive faxes on a Standard plan, that's worth noting. See our full guide on how to receive a fax online for workarounds.

eFax

eFax is one of the oldest names in online faxing. Its mobile app works on both iOS and Android. Enterprise integrations with Microsoft 365 and Salesforce are genuine strengths for large organisations.

Pricing starts around $16.95/month for 150 pages. That's fine if your volume is high. For light users, it's expensive. HIPAA compliance is available but requires a specific plan and BAA request.

iFax

iFax targets teams. It has solid collaboration features like shared inboxes and user management. The iOS and Android apps are polished.

Pricing starts at $8.33/month billed annually. HIPAA is included on paid plans. The per-page overage fees can add up quickly if you send frequently.

FAX.PLUS

FAX.PLUS has strong international coverage and a clean interface. Its free tier allows 10 pages total, which is genuinely useful for one-off situations. Paid plans start at $6.99/month.

HIPAA compliance is available on higher tiers. The Android app is well-reviewed. For international reach, its one of the more reliable options.

FaxBurner

FaxBurner is built around temporary fax numbers. You get a disposable number for receiving faxes, which is useful for short-term projects or privacy-sensitive situations.

The free plan gives you a number that expires after 24 hours. Paid plans start at $9.99/month. It's not the right choice for ongoing business faxing, but it fills a specific niche well.

Best option for iPhone users

If you're on iPhone, Faxend is the most direct choice. The native app is available on the App Store and handles document scanning, PDF attachment, and sending in a few taps.

iFax also has a strong iOS app if you need team features or shared inboxes. FAX.PLUS works well on iOS too, especially for international sending.

One thing worth knowing: if you want to send without creating an account, Faxend's Basic plan is the only option on this list that allows that. You pay once, send your pages, done. No login required. That's covered in detail in our post on fax apps for iPhone without a subscription.

Best option for HIPAA compliance

HIPAA compliance in faxing comes down to two things: encryption and a signed Business Associate Agreement. Under HHS guidelines, covered entities must ensure their vendors protect PHI appropriately.

Faxend offers AES-256 encryption on every plan, including the $2.99 Basic. A BAA is available for healthcare users. That's notable because most competitors restrict HIPAA features to mid-tier or enterprise plans.

iFax also includes HIPAA on paid plans with a BAA available. eFax supports HIPAA but you need to specifically request the BAA and confirm your plan qualifies.

If you're in healthcare and send even occasional patient documents, confirm BAA availability before committing to any service. Don't assume HIPAA-ready means a BAA is automatically provided.

Best option for occasional use

Most people don't send faxes every day. A monthly subscription for something you use twice a year makes no financial sense.

Faxend's $2.99 Basic plan is the clearest answer here. Five pages, 30-day credit, no account. If you need more pages occasionally, you can buy another Basic credit rather than committing to a monthly fee.

FAX.PLUS's free tier (10 pages lifetime) is useful for a single one-off situation. After those pages are gone, you're on a paid plan.

FaxBurner's free temporary number is good if you need to receive one fax quickly and don't care about the number persisting.

How to choose the right app for you

Run through these questions before you commit to anything.

• How many faxes per month? Under 5: Basic plan or free tier. 5 to 20: Standard plan. Over 20: Pro or a high-volume subscription.
• Do you need to receive faxes? You need a dedicated number for that. Faxend's Pro plan includes one. eFax and iFax include it on most paid plans.
• Is HIPAA required? Faxend covers all plans. iFax covers paid plans. Confirm BAA availability with any provider before sending PHI.
• Do you need Android? Faxend's native app is iOS only right now. Android users can use the web app at faxend.com/send, which works well in mobile browsers. iFax and FAX.PLUS have native Android apps.
• Do you need team features? iFax and eFax are stronger here. Faxend is built for individuals and small practices rather than large teams.

There's no single winner for every situation. But for most individuals and small healthcare or legal practices, Faxend's pricing model is the most straightforward on the market in 2026.
