Best Fax Apps in 2026: iOS and Android Ranked

The best fax apps in 2026 are iFax for regular iPhone users, Fax.Plus for Android and cross platform use, and pay per use options like Genius Fax for occasional senders. I sent the same five page test document through eight apps on both platforms to rank them. Here is what held up.

How I Tested These Fax Apps

Every app in this roundup got the same workout. I sent a five page test document, a mix of typed text, a photo, and a handwritten signature, from both an iPhone and an Android phone to a physical fax machine, then repeated the send to an online fax number.

I scored each app on five things: how fast I could go from install to first fax, scan quality on the receiving end, delivery reliability, how clearly pricing was explained before checkout, and how painful cancellation was. The first thing I check in any fax app is whether the price appears before or after you have done the work of scanning a document. A surprising number wait until the send button.

This piece focuses on mobile apps. If you mostly fax from a computer, my guide to the best online fax services covers web-first options in more depth, and you can browse all of our fax app and service reviews for single-service deep dives.

Quick Comparison: Eight Fax Apps at a Glance

Here is the short version. Pricing in this category changes often, so treat the pricing column as a model rather than a quote, and confirm current rates on each provider’s site before you pay.

The Best Fax Apps for iPhone

iOS has the deepest pool of fax apps, and also the most aggressive subscription tactics I have seen in any App Store category. These four earned a spot after testing.

iFax: best overall on iOS

iFax has been in this business since 2008 and the polish shows. The built in scanner handled my handwritten signature page better than any other app I tested, with automatic edge detection and a contrast boost that kept faint pen strokes readable on the receiving machine.

• Pros: excellent scan quality, inbound faxing with a dedicated number, transmission history that doubles as an audit trail
• Cons: pricing leans hard toward annual billing, and light users end up paying for capacity they never use

iFax makes the most sense if you send and receive faxes weekly. As of writing, plans typically land somewhere around $9 to $25 per month depending on volume, but check current pricing before subscribing.

Faxend: fastest photo to fax on iPhone

Full disclosure: Faxend is the app we build, so read this pick knowing that. The reason it exists is speed. You photograph a document or pick a PDF, enter the number, and the fax is on its way in a couple of taps, without an account wall standing between you and the price.

• Pros: the shortest install to sent time of anything I tested, free to download with sending costs shown upfront
• Cons: iOS only, with no Android or desktop version, so heavy daily faxers are better served by a cross platform service like Fax.Plus or iFax

Sending is paid, per fax or through a plan, so do not expect unlimited free faxing. For someone who faxes a few times a month from a phone, that trade is the point.

FaxBurner: best for receiving a one time fax

FaxBurner’s party trick is a temporary inbound number on its free tier. When a clinic or bank insists on faxing something to you, FaxBurner gets you a number in about a minute, and the fax arrives as a PDF in the app and your email.

• Pros: free temporary inbound number, clean iOS app, sensible paid tiers if you outgrow the free one
• Cons: the free number expires and free sending is very limited, so it is a receiving tool first

eFax: best if your office already uses it

eFax is the oldest name here, and the official eFax site positions it as the corporate standard, which is fair. The mobile app is competent rather than exciting, and delivery in my tests was reliable. The subscription costs more than most rivals, so it earns its keep mainly when your workplace already runs on it.

• Pros: long track record, large file support, solid delivery confirmations
• Cons: among the pricier subscriptions in this roundup, and cancellation has historically required more steps than it should

The Best Fax Apps for Android

Android users get fewer choices than iPhone owners, but the quality at the top is equal.

Fax.Plus: best overall on Android

Fax.Plus was the most consistent performer across both platforms in my testing. The Android app mirrors the iOS and web versions, so your fax history follows you between devices, and the free tier let me send a short test fax before entering any payment details.

• Pros: true cross platform sync, a working free tier for a first test, clear per page limits on every plan
• Cons: the free tier is small, and international sending burns through page allowances quickly

MyFax: simplest monthly plans

MyFax keeps things plain. One number, a monthly page bundle, send and receive from the app or by email. During testing, delivery was reliable and the app never tried to upsell me mid task, which I appreciated more than any feature.

• Pros: predictable monthly pricing, email to fax works well alongside the app
• Cons: no meaningful free tier, and the interface feels dated next to iFax or Fax.Plus

Municorn Fax (ComFax): fast sends, read the trial terms

Municorn’s fax app, branded ComFax in some regions, sends quickly and the scanner is decent. My caution is the pricing flow. The trial converts to a subscription faster than most people expect, so read the confirmation screen carefully before you tap.

• Pros: quick setup, capable scanner, available on both platforms
• Cons: trial to subscription conversion is aggressive, and weekly billing can surprise you on a bank statement

Best Picks for Occasional Faxing

If you fax a few times a year, a subscription is the wrong shape entirely. Two patterns fit better.

The first is a free web sender for small jobs. FaxZero sends a short fax at no cost from a browser, with an ad on the cover page, and it remains the most dependable free option I have tested. It is a website rather than an app, so there is no built in scanner, but for a page or two it does the job.

The second is pay per use credits. Genius Fax sells credits that do not expire on a monthly clock, so you can load a few dollars and fax twice a year without a recurring charge. Faxend takes a similar approach on iPhone if you want the scanner and the phone workflow without a subscription.

I keep a running list of the no cost options in my guide to the best free online fax services, including the page limits each one enforces.

Pricing Traps to Watch Before You Subscribe

Fax apps are one of the few app categories where the pricing dark patterns are worse than the faxes. Four traps came up repeatedly in my testing.

Weekly billing disguised as cheap. A price like $4.99 sounds harmless until you notice the small “per week” underneath. That adds up to over $250 a year in a category where solid annual plans cost far less.

Trial timers that start before your first fax. Some apps start a three day trial at install, not at first send. Install on Friday, fax on Monday, and you may already be a paying customer.

Page counts that include the cover sheet. If a plan gives 100 pages and every fax spends one on a cover page, your real capacity is lower than advertised.

Cancellation buried outside the app. For app store purchases, cancellation happens in your device’s subscription settings, not inside the fax app itself. Apps rarely point this out.

How to Choose the Right Fax App

After testing all eight, my advice comes down to a short sequence.

1. 1
   Count your monthly pages. Under ten pages a month points to pay per use credits or a free web sender. Over fifty points to a subscription with a receiving number.
2. 2
   Decide if you need to receive. A dedicated inbound number is the main thing subscriptions buy you. If you only send, do not pay for one.
3. 3
   Check the billing period twice. Confirm whether the listed price is weekly, monthly, or annual before entering payment details.
4. 4
   Send a test fax first. Use a free tier or a single credit to fax yourself one page with handwriting on it. Scan quality differences show up immediately.

My picks stand: iFax for regular iPhone users, Fax.Plus for Android and cross platform work, Faxend when speed from an iPhone matters most, and FaxZero when the job is small enough to be free. Whichever you choose, none of them require a fax machine, a landline, or a trip to a copy shop.
