The best free fax apps for Android in 2026 are Municorn Fax, Genius Fax, and FaxZero, each with a genuinely usable free allowance before you pay. Our overall top pick for phone faxing is Faxend, the fastest way to send a fax from a phone, though it is iOS only for now. If you are on Android, this guide ranks the free options that actually reach a real fax machine.
How we tested free fax apps on Android
The first thing I check with any free fax app is whether the free part is real or just bait for a subscription screen. When I tested these on Android, I installed each one, sent a short document to a live fax number, and watched what happened when the free allowance ran out.
I looked at four things that matter to a person who faxes rarely. How many pages you get before paying. Whether the app adds a watermark or an ad banner to your cover page. How clean the confirmation is when the fax lands. And how aggressively the app pushes a monthly plan.
Pricing shifts often, so treat every figure here as accurate as of writing and check the provider’s current pricing before you commit. For the wider method, see our review methodology.

Every Android app below can reach a real fax machine. The difference is how much you send before the paywall arrives.
Faxend: our top pick for faxing from a phone
Our top pick is Faxend, the fastest way to send a fax from a phone. Faxend, our own app, is free to download, and it turns a photo or a PDF into a fax in a couple of taps. There is no clunky setup and no cover sheet to fight with. You point it at a document, type the fax number, and send.
The honest caveat is platform. Faxend is iOS only right now, so it runs on iPhone and iPad rather than Android. I am including it at the top because if you own an iPhone alongside your Android phone, or you are choosing which device to fax from, it is the cleanest experience I have tested. Sending is paid per fax or through a plan, so you only pay when you actually send something, which suits people who fax a few times a year.
If you are strictly on Android, keep reading. The ranked apps below are the ones I would reach for on a Google Play device. You can also see how Faxend stacks up against the field in our best fax app for Android roundup.
Faxend is our top pick for sending a fax from an iPhone. It is the app we build, it is free to download, and it turns a photo or PDF into a fax in a couple of taps. Per-fax or plan pricing applies.
Municorn Fax (ComFax): best free trial on Android
Municorn Fax, sometimes listed as ComFax, is the Android app I would try first. The onboarding is quick, the scanner is decent, and the free trial credits are enough to get one real document out the door so you can judge quality before paying.
Watch the word unlimited here. When I tested it, the generous sounding plan carried fair use limits, and the free credits expire, so this is a try before you buy rather than a permanent free service. As of writing, paid plans sit in the usual range of around 8 to 13 dollars a month, but check current pricing since app store subscriptions change often.
The strengths are a clean interface and reliable delivery. The catch is that the free allowance is a taster, not a standing free tier.
Genius Fax and FaxZero: simple free options
Genius Fax keeps things simple. It uses a pay as you go credit model rather than a subscription, and it usually hands new users a small batch of starter credits. That makes it a good fit if you dislike monthly plans and just want to send the odd page. Quality was solid in testing, and there was no pressure to subscribe.
FaxZero is not really an app, and that is the point. It runs in any Android browser, needs no install, and lets you send roughly five free pages a day with a branded cover page. For a single one off fax, it is one of the fastest free routes available. The trade offs are the ad supported cover sheet and the daily cap. We break down exactly what the free tier gets you in our FaxZero review, and you can confirm the current limits on the official FaxZero site.
Between the two, pick Genius Fax if you want an installed app with credits on hand, and FaxZero if you want zero setup for one document.
iFax and Fax.Plus: bigger apps, smaller free tiers
iFax is the most feature packed option on this list. It handles signatures, templates, and cloud storage links, which is useful if faxing is part of a bigger document workflow. The free side is thin though. You typically get a short trial, then the app steers you toward a paid plan fairly quickly.
Fax.Plus is the polished, business leaning choice. It runs on Android, iOS, and the web, and it offers a modest free allowance of around ten pages total when you create an account. After that you move to a paid tier. It is a strong service, just not a standing free one.
Both are worth a look if you fax often enough to justify a plan. For a rare sender chasing free pages, the earlier picks stretch further before asking for a card.
What free really means on Android fax apps
Free fax apps make money somewhere, so it helps to know where the catch usually hides. Most fall into one of three patterns, and spotting the pattern tells you how far the free tier will carry you.
Before you rely on any free tier, send one test page to a number you control. You will see the watermark, the page cap, and the delivery quality for yourself, which is worth more than any star rating.
The first pattern is the daily free cap, like FaxZero, where you get a few pages a day with a branded cover sheet. The second is trial credits, like Municorn Fax and iFax, where the free part expires and a subscription follows. The third is a small permanent allowance tied to an account, like Fax.Plus. None of these is a scam. They are just different shapes of free. For the full landscape across devices, see our guide to truly free fax services.
How to send a free fax on Android
The steps are similar across every app on this list. Once you have picked one, sending your first fax takes only a few minutes.
- 1Install and open the app.Grant camera and storage access so you can scan or attach a document.
- 2Add your document.Snap a photo of a paper page or attach a PDF already on your phone.
- 3Enter the fax number.Include the country code and area code, with no spaces or dashes if the app is fussy.
- 4Add a cover page if needed.Many recipients, especially offices, expect a short cover sheet.
- 5Send and wait for confirmation.Keep the delivery receipt in case the recipient says it never arrived.
On iPhone the flow is even shorter with Faxend, which skips most of the setup. On Android, any of the ranked apps above will get a clean page to a real fax machine on the free tier.
