How to Send a Fax From Your iPhone for Free

With Fax Burner, you can fax up to five pages, and receive up to 25 fax pages, per month for free. These free features apply even when you use Fax Burner to fax from your computer.

To start sending a fax from your iPhone, download and launch the app, enter your email address and a password to create a free account, then follow these steps:

1. Tap Compose a Fax.
2. In the To field, enter your recipient's fax number. In the Cover letter note field, you can type some notes, but this is optional.
3. Tap the plus (+) icon next to Pages to fax.
4. Select Take Photo to take a picture of the document you want to fax. If you already have the image ready, select Choose From Library or Choose From Dropbox.
5. If you want to fax more than one page, tap the same plus (+) icon again and repeat the previous step.
6. Once you're done, tap Send Fax to fax from your iPhone. Once your fax has been sent, you'll see a Your fax is on its way popup.

In the above images, you'll also notice a green pencil icon on the uploaded images. Tapping on it allows you to edit the picture. You can add text, annotations, and a signature to the file you want to fax.

In case you uploaded the wrong image(s), just tap the blue Delete and start over button to re-upload your files easily.

When you need to receive a fax, Fax Burner gives you a toll-free fax number that you can use for up to 24 hours. At the moment, only United States phone numbers are offered, and the number expires after 24 hours, so you have to generate a new one every time.

Any time you need to fax more than five pages, Fax Burner offers a monthly and yearly subscription plan. The monthly plan costs $12.99 and includes 500 inbound and outbound pages.

The Best Alternative Fax Apps for iPhone

If you're not happy with Fax Burner, you can check out a few other apps to fax from your iPhone. Below, we'll cover the unique aspects of each app and how they may suit your faxing needs the best.

FAX from iPhone

FAX from iPhone lets you fax from more than 90 countries. The app's subscription plan makes it suitable for those who want to send and receive a large number of faxes without incurring increasing costs when more pages are faxed.

It offers three subscription plans: a one-week plan at $9.99, a one-month plan at $24.99, and a one-year plan at $249.99. All three plans include unlimited faxes during the subscription period.

Another plus point of the app is that it lets you send the first fax from your iPhone for free, so you can test it out before committing to any plan.

FAX Free

FAX Free has a much cheaper subscription plan compared to FAX from iPhone. The weekly plan costs $6.99 and the yearly plan costs $39.99.

However, although the app's subscription plans let you send an unlimited number of faxes, it does not allow you to receive them. Therefore, it's most suitable for people who want to fax out a lot of documents but don't need to receive any.

Similar to FAX from iPhone, you can send a fax from your iPhone for free before subscribing. The app also offers a three-day free trial, but you'll need to enter your payment details first.

Honorable Mentions for iPhone Faxing

As honorable mentions, Tiny Fax and Genius Fax are two other apps worth considering.

Similar to FAX from iPhone, Tiny Fax also allows you to send and receive unlimited faxes. Its subscription plans are cheaper, too—likely because it only lets you fax from 50 countries instead of 90.

If this regional limitation isn't an issue for you, Tiny Fax is a good, cheaper alternative to FAX from iPhone. I also liked that Tiny Fax lets you lock the app with Face ID for extra privacy.

Lastly, Genius Fax's payment structure differs noticeably from all the other apps we've discussed. You don't need to pay for a subscription plan. Instead, you purchase credits to send or receive faxes.

According to Genius Fax's Help page, the credits never expire and will remain in your account. Hence, it's a more flexible iPhone fax app as you won't be tied up by a subscription plan with a fixed end date, which may otherwise cause the worry that you're not making the most out of your paid plan.

The main downside with Tiny Fax and Genius Fax is that they don't offer a free test fax. You'll have to pay for a subscription or credits upfront to fax from your iPhone, so our top recommendations are still the ones we listed early on.

Generally, the key functions of various iPhone fax apps are more or less the same. Ultimately, the different price points become the deciding factor as to which app will suit your needs properly.

Fax Burner is the best overall app to fax from your iPhone if you only need to send a few faxes as a one-off event. If you find it easier to work on a computer, you can also consider some Chrome extensions to fax from your desktop or send a fax from Gmail.
