Faxing has remained relevant in many workplaces because it supports the transmission of signed documents. It also complies with regulations in regulated industries, and handles sensitive information that can't always be transmitted securely via email. What changed is how we send these files. Many professionals now work from their phones, which makes mobile fax apps far more practical than a machine sitting in a corner.
Recent numbers paint a clear picture. Researchers expect the global fax services market to reach a value of USD$5.96 billion by 2028. This helps explain why iPhone fax apps remain valuable in 2025. (1)
This guide highlights the best free fax apps for iPhone. You'll also see what makes each option useful and how to pick the app that fits your daily work.
What Professionals Need From a Free Fax App
Before looking at individual iPhone fax apps, it helps to focus on a few basic features. These points make it easier to understand why some apps feel more dependable than others.
Most professionals want an app that sends clean, readable documents. A job offer, medical form, or signed agreement must arrive in a format that appears correct to the recipient. Delivery notices also help because they provide clear confirmation that a fax arrived.
Privacy is another priority. Some industries must follow strict data rules. If you work with patient records, financial files, or legal documents, you need a service that explains how data is protected. This is important considering that the global average cost of a data breach is USD$4.4 million this year. Not every free plan supports advanced privacy settings, but starting with a provider that takes security seriously can save time later. (2)
Free plans also differ a lot. Some include page limits. Some offer short trials without long-term commitments. These limits don't make the apps useless. They simply help you test the workflow before deciding whether a paid plan fits your needs.
Top Free Fax Apps for iPhone in 2025
With those basics in mind, here are the strongest options available on the App Store. Each one works well for different types of jobs and fax habits.
1. eFax
eFax is one of the most recognized names in online faxing. The iPhone app is free to download, and new users can explore a limited free trial tied to its paid plans. This gives you an easy way to try eFax before subscribing.
Inside the app, you can send and receive faxes, sign documents digitally, attach files from cloud storage, and store documents for later use. Paid plans include lifetime fax storage, which makes it easier to organize older files.
One of the strong points of eFax from iPhone is flexibility. You can fax through the iOS app, your email account, or the web portal. This style works well for professionals who switch between devices. Some eFax plans also support HIPAA compliance, which helps clinics and hospitals that deal with sensitive data.
Overall, eFax is a solid first choice. It works smoothly on mobile and scales easily if your fax volume increases.
2. iFax
iFax is another good option for iPhone users. It supports both outgoing and incoming faxes, digital signatures, and file imports. The app sometimes offers light-use options or trials, so checking the most current details is always helpful.
iFax fits users who handle occasional faxes and want a simple interface. When you need more pages or stronger privacy tools, you can move to a paid plan. Some plans include HIPAA support, which is beneficial for teams that handle sensitive or protected documents.
Its clean layout and consistent performance make iFax a practical choice for users who don't fax every day but want a reliable backup.
3. FAX.PLUS
FAX.PLUS is known for its modern design and strong focus on secure faxing. The free plan includes a total of 10 pages. This doesn't cover heavy use, but it's sufficient for testing the app or sending a few important pages.
The iPhone app supports scanning through the camera, importing files from cloud drives, and sending PDFs with good clarity. FAX.PLUS also offers HIPAA-ready plans for companies that depend on privacy rules.
FAX.PLUS works best as a lightweight starting point. If you like the interface and send only a small number of pages, the app handles those tasks consistently well.
4. Genius Fax
Genius Fax uses a simple approach. It doesn't offer a long-term free tier, but you can send faxes without a contract. Instead of paying monthly, you purchase pages as needed.
Bulk pricing starts at about 19 cents per page, while individual pages cost slightly more when purchased in small amounts. You can also subscribe monthly if you want a dedicated fax number for incoming pages.
Genius Fax fits users with irregular fax needs. It's a good tool for someone who may send a few pages today and none for several weeks.
5. FaxBurner
FaxBurner is designed for quick use. Creating a free account provides you with a temporary fax number that remains active for 24 hours. You can receive up to 25 pages per month and send up to 5 pages total on the free plan.
You can scan documents using your camera or attach files from storage. Sending and receiving also work through email, which makes the setup simple.
FaxBurner is ideal for freelancers or anyone who occasionally sends faxes. If your volume grows, you can upgrade to a paid plan with a permanent fax number.
6. MyFax
MyFax has been around for many years. While it doesn't offer a typical free plan, it often appears in comparisons because many small offices test it when exploring subscription-based faxing.
A common entry plan costs about USD$12 per month and includes several hundred combined inbound and outbound pages. Users receive a dedicated fax number, along with email-to-fax features and mobile compatibility.
MyFax makes sense when you already know that you'll send and receive a steady volume of pages. It's not designed as a long-term free option, but it's still useful when comparing paid solutions for business use.

Key Features to Check Before Choosing an App
Once you have a shorter list, focus on the details that affect your day-to-day use. These features make a noticeable difference once faxing becomes part of your regular routine.
Security and Privacy
Look for apps that clearly describe their security standards. Encryption, storage practices, and account protections should be easy to find. Some apps offer HIPAA-ready options for healthcare workflows, which is a must, as every single HIPAA violation can result in a fine of up to USD$100,000. eFax and FAX.PLUS both mention compliance-friendly choices in their paid tiers. (3)
If you work with sensitive files, starting with a service that supports these standards can make future upgrades smoother.
Scanning and File Quality
A fax app is only as good as the document it sends. Most iPhone fax apps utilise the camera as a scanner, so the scanning tools are crucial. Look for auto-cropping, text enhancement, and multi-page PDF support. These features keep documents readable and reduce follow-up requests.
Ease of Use
An app should feel simple from the first tap. Clear menus help you send files quickly, and a straightforward history page makes tracking easy. eFax supports faxing from email, the web portal, and the iPhone app. This kind of flexibility is helpful when your files come from different sources.
Testing one fax before using the app for important documents is a good habit. It allows you to see how the final output appears on the receiving end.
When You Should Think About Upgrading to a Paid Fax Plan
A free plan works well for occasional tasks. However, once you send or receive documents regularly, you may need more pages, higher attachment limits, or a dedicated fax number.
Paid plans often include features that make everyday work easier, such as better storage, larger files, and a consistent caller ID. If clients or partners expect a stable fax number, upgrading helps you meet that expectation.
The right time to upgrade to a paid plan is when faxing becomes a regular part of your weekly work, rather than an occasional task.
Alternatives if You Don’t Want a Fax App
Not every team depends on mobile faxing. Some prefer other tools that better fit their shared office routines or desktop-heavy workflows.
You can try:
Online fax platforms that work in a browser
Multi-function printers that offer scan-and-fax features
VoIP services with fax add-ons
These options are helpful when several employees share fax duties or when most documents live on work computers. The iPhone app can still serve as a backup for urgent tasks outside the office.
Simple Tips to Avoid Problems When Faxing From iPhone
Small habits make mobile faxing easier and reduce the chances of failed transmissions.
Take document photos in bright, even lighting
Check page limits on free plans before sending large files
Avoid peak hours when possible to reduce delays
Compress image-heavy PDFs when the app allows it
These steps keep your faxes clear and help you make the most of any free or trial limits you have.
Conclusion
Faxing from an iPhone is now a practical part of everyday work. The apps listed here cover a wide range of needs. eFax stands out as the best all-around choice for professionals seeking a comprehensive mobile and desktop workflow. It offers digital signatures, cloud storage support, and strong privacy options in higher-tier plans.
Each app has strengths, and the best choice depends on your document volume, privacy needs, and work routine. Testing one or two apps with real files is the simplest way to see what feels comfortable. Once you find the right match, your iPhone becomes a dependable way to send and receive important files without slowing down your day.
