Fax machines haven't disappeared — healthcare, legal, and government sectors still rely on them daily. But the Android fax app has made physical hardware irrelevant for most users. Why drive to a UPS Store and pay $2–5 per page when you can send from your phone in under two minutes?
The problem: not all Android fax apps are equal. Some have spotty delivery rates. Others hide costs behind free trials that auto-upgrade. A few claim HIPAA compliance without the BAA to back it up.
We evaluated six leading fax apps across five criteria: Android app quality, pricing transparency, delivery reliability, HIPAA compliance, and ease of getting your first fax out. Here are the best Android fax apps in 2026.
| App | Best For | Price Starts At | HIPAA | Free Option |
|---|---|---|---|---|
| mFax | Best overall | Pay-as-you-go | Yes | No subscription needed |
| Fax.Plus | Best free plan | Free (10 pages total) | Enterprise tier | 10 pages free |
| iFax | Best security | ~$8.33/mo (annual) | Yes | 7-day trial |
| eFax | Best established | ~$16/mo | Yes | 14-day trial |
| FaxBurner | Best occasional use | Free / $14.95/mo | No | Free tier (limited) |
| CocoFax | Best budget pick | $4.99/mo | Yes | Free trial |
What We Tested
Every app on this list was evaluated against five criteria that matter for Android users specifically:
- Android app quality — native app performance, camera scan integration, notification reliability, Android file picker compatibility
- Pricing transparency — no hidden per-page overages, clear subscription terms, honest free tier limitations
- Delivery reliability — confirmation receipts, success rates on first attempt
- HIPAA compliance — does the service offer a BAA? Is encryption documented?
- Ease of first fax — how quickly can a new user send their first fax from a cold start?
Why Android Fax Apps Still Matter
Fax accounts for roughly 70% of all healthcare communications. Legal, insurance, and government sectors continue to require fax for official document submission. Android fax apps have replaced the physical machine for most individual users — they're cheaper, faster, and don't require a phone line.
1. mFax — Best Overall Android Fax App
mFax.to is the top pick for most Android users. Over 5 million people use it across iOS and Android, and the Android app is polished, fast, and straightforward. Upload a PDF, snap a photo with your phone's camera, or import from Google Drive — then enter the fax number and send.
The key differentiator: pay-as-you-go pricing. If you fax occasionally, you don't need a monthly subscription. Pay per fax, only when you actually send. For regular faxers, subscription plans start competitively.
mFax hits the sweet spot between simplicity and capability. The Android app is genuinely well-built — the camera scanner auto-detects document edges, crops, and enhances the image before sending. You get a delivery receipt for every outbound fax so you know it actually arrived.
For occasional faxers, the pay-as-you-go model is a real advantage over services that force you into a monthly plan you'll forget to cancel. For heavy faxers, subscription plans keep costs predictable. The mFax Business tier adds virtual fax numbers, team accounts, and HIPAA-ready infrastructure for healthcare and legal teams.
Pros
- Pay-as-you-go — no forced monthly subscription
- Native Android app with camera scan built in
- HIPAA compliant with TLS encryption
- 4.8-star App Store rating, 5M+ users
- Fax to 90+ countries with delivery confirmation
- Google Drive, Dropbox, and Box integration
- mFax Business adds team accounts and virtual numbers
Cons
- No permanently free plan (pay-as-you-go or subscription)
- Business plans required for multi-user team features
Pricing: Pay-as-you-go (no subscription) or plans starting around $7.99/month. Annual billing reduces costs further. Business plans from about $9/mo — fully customizable, with no rigid tiers: you build your own plan by dialing in the seats and pages you need.
Best for: Most Android users — especially those who need a reliable app without a forced subscription.
Try it: mFax.to
2. Fax.Plus — Best Free Plan
Fax.Plus is the right choice if you need a zero-cost starting point. The permanently free tier gives you 10 pages total — not per month — with no credit card required. For someone who needs to fax a contract once or submit a form to a government agency, it's a genuinely useful free option.
Beyond the free tier, Fax.Plus has the most advanced feature set of any app in this category: scheduled sending, bulk faxing, Slack integration, and the widest international coverage (40+ countries with local numbers).
Fax.Plus is a capable, well-designed service. The Android app is clean and the scheduled send feature is unique — you can queue a fax to go out at a specific time, useful for off-hours submissions or international time zones.
The important caveat: the free plan's 10 pages are lifetime pages, not monthly. Once you've used them, you'll need a paid plan. And HIPAA compliance requires an enterprise subscription that's significantly more expensive than the base tiers. If HIPAA is a hard requirement, mFax or iFax offer better value.
Pros
- Permanently free plan — 10 pages, no credit card
- Scheduled fax sending (unique feature)
- SOC 2 Type II, GDPR, and HIPAA certified
- 40+ country local fax numbers
- Google Drive, Dropbox, Slack, OneDrive integration
- Strong API for developer use cases
Cons
- HIPAA compliance only on enterprise-tier plans
- Free plan has no inbound fax number
- 10-page free total is not per-month — it's a one-time allowance
Pricing: Free (10 pages lifetime); paid plans from $6.99/month. Local numbers in 40+ countries.
Best for: Users who need to fax occasionally and want a zero-cost starting point, or power users who need scheduled sending and API access.
3. iFax — Best for Security and HIPAA Compliance
iFax leads the field on security credentials. The app uses 256-bit AES encryption, has AI-powered content verification, and carries HIPAA, GLBA, and SOC 2 certifications. With over 5 million customers and 1M+ Google Play downloads, it's a well-established platform.
For healthcare providers, legal firms, or anyone handling sensitive documents, iFax's security posture is the most documented and defensible of any option on this list.
iFax's Android app is polished and feature-complete. The AI verification feature is genuinely useful — it flags low-quality scans or detection issues before you hit send, reducing failed transmissions. Electronic signature support is baked in, which saves a round-trip for contracts.
The pricing is higher than most alternatives, particularly at mid-tier. But for organizations where HIPAA is non-negotiable and they want documented, auditable compliance, iFax justifies the cost. For a more detailed breakdown, see our full iFax review.
Pros
- 256-bit AES encryption with HIPAA, GLBA, SOC 2 compliance
- AI content verification catches errors before sending
- Cross-platform sync: Android, iOS, web
- Built-in e-signatures
- Cloud integrations: Google Drive, Dropbox, Box
- 5M+ customers, 1M+ Google Play downloads
Cons
- More expensive than competitors at mid-tier pricing
- 7-day trial limited to 10 pages
- Some users report billing friction when canceling
Pricing: Free trial (7 days, 10 pages); paid plans from approximately $8.33/month (annual billing). Subscribe via the website for the best rate.
Best for: Healthcare providers, legal professionals, and anyone who needs the most rigorous HIPAA compliance documentation.
4. eFax — Best Established Service
eFax has been in the fax business since 1995. With 11 million users and 30+ years of operational history, it's the most established online fax service in the world. The Android app connects to your eFax account and handles both sending and receiving with a traditional inbox-style interface.
For users who want a proven, enterprise-grade service with a long track record, eFax delivers — especially for organizations that already have eFax accounts established.
eFax is the safe, institutional choice. If your organization already mandates eFax, the Android app is a functional companion. The Gmail and Outlook integration is a standout: you can send a fax directly from your email client without opening a separate app.
The downsides are real: eFax is more expensive than newer alternatives, and the Android app has a mixed reputation in reviews — not broken, but not as polished as mFax or iFax. The cancellation process has drawn complaints. For a full breakdown of pricing and alternatives, see our eFax review.
Pros
- 11 million users, 30+ years in operation
- Fax to 200+ countries — widest international reach
- HIPAA compliant on business plans
- Native Gmail and Outlook integration
- Email-to-fax for sending without opening the app
- Enterprise team accounts available
Cons
- Higher price point ($16–20+/mo) than newer competitors
- Android app reviews are mixed (cancellation UX issues)
- No free plan or pay-as-you-go option
- Contract cancellation reported as difficult by some users
Pricing: Plans from approximately $16/month. 14-day free trial available. Often discounted to $5/month for the first month.
Best for: Organizations already using eFax, or users who need the widest international fax coverage (200+ countries).
5. FaxBurner — Best for Occasional Use
FaxBurner is the most accessible entry point for someone who needs to send a fax once in a while and doesn't want a monthly bill. The genuinely free tier includes 25 inbound pages and 5 outbound pages — enough for a single tax filing or a contract submission.
The catch: the free fax number is temporary and expires after 24 hours. For one-time use, that's fine. For anything recurring, you'll need a paid plan.
FaxBurner works exactly as advertised for occasional use: you get a number, send a fax, done. The photo-to-fax workflow is fast — snap a document with your Android camera and it's on its way. For anything beyond occasional personal use, the lack of HIPAA compliance and lower transmission quality are real limitations.
The paid Professional plan ($14.95/month) is reasonably priced but doesn't offer much that mFax or iFax don't do better. FaxBurner's real value is the free tier for one-time use.
Pros
- Genuinely free tier — 25 in / 5 out pages, no credit card
- Photo-to-fax directly from Android camera
- Permanent fax number on paid plans
- Simple, no-clutter interface
- Document signing built in on paid plans
Cons
- Free fax number expires after 24 hours
- No HIPAA compliance
- Fax quality is lower than competitors, especially for images
- Monthly-only billing (no annual discount)
- No live chat on the free plan
Pricing: Free (25 in / 5 out pages; 24-hr temp number); Professional $14.95/month (500 pages, permanent number); Premier $24.95/month (2,000 pages).
Best for: Someone who needs to fax once or twice a year and doesn't want any ongoing commitment.
6. CocoFax — Best Budget Paid Plan
CocoFax has the lowest entry price of any fax service on this list at $4.99/month, and it claims triple compliance: HIPAA, GDPR, and PHIPA. For users who need a low-cost paid plan with compliance coverage, it's worth considering.
The caveat: CocoFax has a mixed reputation for fax delivery reliability and a limited Google Play presence compared to competitors.
CocoFax's Gmail integration is genuinely clever: if you live in Google Workspace, you can send a fax directly from Gmail with a Google Drive attachment — no separate app window needed. For teams already embedded in Google's ecosystem, this is a real workflow improvement.
The reliability concerns are real, though. Independent testing has flagged a higher-than-average fax drop rate, and user reviews on Trustpilot are mixed. For mission-critical faxing (medical records, legal filings), the risk isn't worth the savings. For low-stakes use where occasional failures are acceptable, the price makes sense.
Pros
- Lowest paid plan price: $4.99/month
- HIPAA, GDPR, and PHIPA compliance claims
- Native Gmail and Google Drive integration
- No extra app needed for Google Workspace users
- E-signature support included
Cons
- Reported ~20% fax drop rate in independent testing
- Limited Google Play app presence
- Subscription cancellation has drawn Trustpilot complaints
- Support response times inconsistent
Pricing: Lite plan at $4.99/month (60 pages); higher tiers available. Free trial with a personal fax number.
Best for: Google Workspace users who need a low-cost paid plan and can tolerate some reliability variability.
What to Look for in an Android Fax App
Not all fax apps are equal. Here's what separates a good Android fax app from a frustrating one:
Android-Specific Features
A fax app designed for Android should feel native to the platform. Look for:
- Camera integration — auto-detect document edges, crop, and enhance before sending. A good scanner app built into the fax app saves a step.
- Android file picker support — access documents from Google Drive, Dropbox, local storage, or any storage provider in one tap
- Background sending — the fax should send in the background without keeping the app open
- Push notifications — delivery confirmations and inbound fax alerts via Android notifications
- Portrait + landscape support — the app should handle both orientations naturally
Pricing Transparency
The fax app market has a reputation for confusing pricing. Watch for:
- Hidden per-page charges — some plans look cheap until you exceed the page limit
- Auto-renewing trials — read the trial terms before entering a credit card
- Annual-vs-monthly gap — many services are 20–30% cheaper on annual billing; calculate accordingly
- Overage rates — if you go over your page limit, what does each additional page cost?
Watch for Per-Page Overages
Several fax services advertise a low monthly rate but charge $0.03–$0.10 per page once you exceed the plan limit. If you regularly fax multi-page documents, calculate your true monthly cost before choosing a plan.
Delivery Reliability
The only metric that actually matters: does the fax arrive? Look for:
- Delivery confirmation receipts — every outbound fax should generate a confirmation
- Retry logic — if the recipient line is busy, a good service retries automatically
- T.38 protocol support — the standard for reliable digital fax transmission; better services support it
- Uptime history — check user reviews specifically for failed send reports
Free vs. Paid Android Fax Apps
Most "free" fax apps are either trials or very limited free tiers. Here's an honest breakdown:
| Option | What You Actually Get | Best For |
|---|---|---|
| Fax.Plus free | 10 pages total (not monthly), no fax number | One-time personal use |
| FaxBurner free | 25 in / 5 out pages; temp number expires in 24h | Single fax, no ongoing need |
| mFax pay-as-you-go | No subscription; pay per fax sent | Occasional use without monthly commitment |
| iFax 7-day trial | Full features for 7 days; auto-converts to paid | Evaluate before committing |
| eFax 14-day trial | Full features for 14 days | Evaluate before committing |
The cleanest option for occasional faxers who don't want a subscription: mFax pay-as-you-go or FaxBurner free (for a true one-time send). Neither requires a monthly commitment.
For regular use, a paid subscription at $7–15/month is almost always cheaper than store faxing. At $1.89–$5 per page at UPS or FedEx, even a 10-page fax costs more than a month of mFax. See our full comparison of fax services for a detailed cost analysis.
HIPAA-Compliant Android Fax Apps
Healthcare providers, medical offices, and anyone handling Protected Health Information (PHI) need more than just encryption — they need a signed Business Associate Agreement (BAA) with their fax provider.
| App | HIPAA | BAA Available | Notes |
|---|---|---|---|
| mFax Business | Yes | Yes | Required plan: mFax Business (from $9/mo) |
| iFax | Yes | Yes | Available on paid plans |
| eFax | Yes | Yes | Business plans required |
| Fax.Plus | Yes | Yes | Enterprise tier only — significantly higher cost |
| CocoFax | Claims yes | Unclear | Compliance claims disputed in reviews |
| FaxBurner | No | No | Not suitable for PHI |
HIPAA Compliance Requires a BAA
A service saying it is "HIPAA compliant" is not the same as you being HIPAA compliant. You must have a signed BAA in place with your fax provider before transmitting any PHI. Verify this before sending medical records or insurance information.
For healthcare teams needing a reliable, HIPAA-ready Android fax solution, mFax Business is built for exactly this use case — with team accounts, virtual fax numbers, audit logs, and TLS encryption across all plans.
How to Send a Fax from Android
Regardless of which app you choose, the process is the same:
- Download the app from Google Play and create an account
- Add a document — upload a PDF, import from cloud storage, or scan with your camera
- Enter the fax number — include the area code; for international faxes, include the country code (see our international fax guide for formatting)
- Add a cover sheet (optional) — most apps include templates; or use our free fax cover sheet generator
- Tap send — the app transmits and confirms delivery
For a detailed walkthrough, see our how to fax from Android guide.
The Bottom Line
The best Android fax app for most users is mFax.to — it combines a polished Android app, pay-as-you-go flexibility, HIPAA compliance, and a 4.8-star rating from over 5 million users. There's no forced subscription if you fax occasionally, and no compromises on reliability when you do.
For teams and healthcare organizations, mFax Business adds virtual fax numbers, team accounts, and a BAA — starting at about $9/mo.
If you need a free starting point, Fax.Plus gives you 10 pages with no credit card. For one-time use with no commitment, FaxBurner's free tier gets the job done in minutes.
Whatever you choose, any of the apps on this list will cost you less per fax than driving to a store. At $1.89–$5 per page at most copy shops, the math favors going mobile.
