Whether you need a portable solution for your business — or are using them occasionally for personal use — you may only need a free fax app!

Why Use a Fax Application in 2024?

We know that sending a fax doesn’t feel very relevant, but many US organizations haven’t fully transitioned to paperless offices (like the IRS). Therefore, the need for physical documents still exists — and one of the best ways to share physical documents is via fax.

You don’t need to track down a bulky fax machine when you can use your iPhone for the same purpose:

1. Occasional Usage

Most people don’t send or receive faxes every day. Having bulky, expensive equipment doesn’t make sense as an investment.

2. Signing Documents

Many business documents require people to sign and send it a physical document to a recipient. Fax apps to sign documents using your iPhone or iPad are an efficient way to accomplish this.

3. Cost Effective

Fax machines can be costly, and they also require maintenance and a phone line. Using your iPhone to send faxes is much more affordable.

4. Security

To keep data safe, most fax applications use business-grade, 256-bit encryption. When sending sensitive documents, check that your app complies with standards like GLBA and HIPAA.

iFax is an excellent fax app for iPhone, iPad, Android, macOS, Windows, and even a web application. It syncs all your fax documents to the cloud, meaning documents can be accessed on the go.

iFax is exceptionally secure, offering end-to-end AES 256-bit encryption (meaning you or the recipient can only see your data), as well as HIPAA and GLBA-compliant. That means that the best data-sharing practices are applied to safeguard sensitive information in documents.

The application is free to use for up to five pages a month (without needing a dedicated fax number), which is great for personal use. Businesses can opt for the $25/month subscription that offers useful features like optical character recognition, email fax, Dropbox, and more.

2. FAX.PLUS — Great Feature Set

If you’re looking for the best scan and fax app for iPhone, this app is a great option. FAX from iPhone makes the process quick and convenient, thanks to its built-in scanner that supports various documents (e.g., notes, images, books, posters, and tax statements). Since files are also saved in Documents, it’s easy to keep them organized.

Not only can documents be scanned, but they can also be edited, e-signed, shared, and saved in a variety of formats (e.g., PNG, JPEG, PDF). We think the best aspect of this faxing application is choosing any number for fax — and changing it once every month for free. This number can be used to exchange documents anywhere in Canada or the USA.

The handy tracking feature also lets you know when your faxes are delivered to the recipient.

5. Easy FAX — Most Convenient

  • Allows sharing through other applications


  • The premium tier needs improvement

While most fax apps on iOS are easy to use, many have a complicated user interface. For people seeking a simple experience, Easy FAX might be the way to go.

We appreciate the free, built-in support for Apple AirPrint (allowing you to print the faxes received on your iPhone). Users can also send faxes to 25 different countries, import from cloud services, and use accurate document previews.

The app’s paid features include powerful tools like perspective correction, automatic corner detection, color enhancement, and status tracking. You can even connect to social media accounts for easy sharing of files. However, some users report issues with the subscription services (so it may not be worth upgrading to the paid version).

How To Choose the Best App for Faxing from iPhone

You can find a massive list of fax apps on the App Store. Here are some things you should look for when looking to choose the best fax app for iPhone:

Use the Free Trial

Many fax apps offer a free trial before prompting you to subscribe or buy the premium version. Try out the features the fax application offers before purchasing. Also, be warned that some applications will automatically jump to a subscription as soon as the trial expires!

Determine the Limitations

Most fax applications allow you to send a fixed amount of monthly faxes. The number of faxes will depend on your subscription plan. Check the amount you’ll have to pay if you exceed the limit.

Check the User Interface

Your fax app won’t work if you can’t use it properly. Choose an app with an intuitive, modern, clean, and smooth user interface (all options in this article tick those boxes).

If you’re planning to use the application on an iPad, install it there to ensure that it scales properly, like FAX FREE (our current favorite option).

Compare Prices

Fax app pricing is usually based on required featured and chosen subscription tiers. Take some time to compare the prices and the features offered. Even if you want to use them to send simple faxes, each app requires signing up for an account in order to receive a number.

However, each option in our list provides a free trial period (or X amount of sends) before any type of payment is needed.

Check Security Features

Security is essential if you’re faxing documents that contain sensitive data. Check out the description on each app’s App Store page. Ensure the app offers encryption and complies with privacy and security compliances (like GLBA and HIPAA).

One of our top picks is FAX.PLUS, as a lot of their marketing centers around security.

Determine Interoperability

Although it isn’t a necessary feature, it may be beneficial that your fax service can sync across various devices (like Android, macOS, and Windows). One of our top picks is iFax.
