Best Free Online Fax Services 2026: Compare Top Providers

“Free fax” covers very different things: a one-time page allowance, a daily web form, or a trial of a full paid service. We compared the most popular options on what you get for free, what’s included, and what you have to give up to start.

Our Verdict

Healthcare, legal, and government sectors rely heavily on fax services. Nearly 60% of healthcare organizations use fax as their primary method for sharing patient information, driven by HIPAA requirements. Legal and financial sectors depend on fax technology for contracts, court filings, and financial documents.

Understanding Free Faxing: What It Means and When It’s Beneficial

• If you need to send and receive with a dedicated number or a HIPAA-compliant setup, try eFax’s 7-day trial.
• If you need to send only a few pages without having to sign up with a credit card, consider the free plan from Fax.Plus.
• If you want to send one fax without creating an account and don’t mind ads or branding, try FaxZero or GotFreeFax.

1. eFax^®

The eFax Personal plan 7-day free trial includes up to 200 pages. You get a local or toll-free fax number, can send and receive by email, web, or mobile app, and can sign documents electronically. Personal is HIPAA-compliant, though a BAA requires a higher tier.

A credit card is required to start, and the trial converts to a paid plan unless you cancel. If you need a single fax with no commitment, a no-card option below may suit you better. If you want to test a real setup with a number, an inbox, and a compliance path, eFax is a good choice for personal use or businesses of any size.

2. Fax.Plus

Fax.Plus takes a different approach to free faxing than a trial-based service. Instead of temporarily opening up a full paid plan, it gives users a small one-time allowance they can use without entering a credit card. That makes it better suited to someone who only needs to send a few pages and does not need an ongoing fax number or incoming fax capability. The tradeoff is that the free tier is intentionally limited, so it works more like a convenient backup option than a complete fax replacement.

• Choose Fax.Plus if your priority is sending a few pages for free without providing a credit card.
• Choose eFax if you need both sending and receiving, a dedicated fax number, or a larger allowance to test the service.

3. iFaxapp

iFax is closer to a traditional online fax service than a bare-bones free fax website. Its free option is a limited trial of the paid platform, which gives users a chance to test both sending and receiving along with its apps and compliance features. That makes it a better fit for someone evaluating an ongoing fax solution rather than simply trying to send a document or two at no cost.

• Choose iFax if you want to evaluate a mobile-focused fax service with HIPAA and GLBA compliance options.
• Choose eFax if you want twice as many pages during the trial or prefer a more established business fax platform.

4. MyFax

MyFax sits between the ultra-basic free fax sites and more compliance-focused business platforms. Its trial gives users access to a dedicated fax number and both sending and receiving, making it useful for freelancers, home offices, and small businesses that want to see how a full online fax service fits into their workflow. It is less compelling for users who need healthcare-grade compliance or only want to send a single fax.

5. mFax

mFax is primarily aimed at business users, especially organizations concerned about security, compliance, and mobile access. Its free period is designed as a trial of the full service rather than an ongoing free tier, so it makes the most sense for someone comparing professional fax platforms before committing to a subscription. Users who only need an occasional one-time fax may find simpler free services more practical.

• Choose mFax if you expect to fax heavily during the trial and want to test the service without a page cap.
• Choose eFax if you want HIPAA-compliant faxing during the trial.

6. Dropbox Fax

Dropbox Fax is a natural fit for users who already keep documents in cloud storage and want faxing to plug into that workflow. The free option is limited, but it offers a convenient way to send a small number of pages without committing to a subscription, while paid plans add features such as receiving and a dedicated number. It is most appealing for occasional users who value cloud integration and e-signature tools more than a full-featured fax account.

• Choose Dropbox Fax if you only need to send a small number of documents and want a free option that works closely with your existing DropBox account.
• Choose eFax if you need incoming faxes, a dedicated number, or enough capacity for more than occasional outbound use.

7. CocoFax

CocoFax gives occasional users a low-commitment way to try online faxing without immediately entering payment information. The free allowance is modest, but the service includes many of the conveniences people expect from a modern fax platform, including email-to-fax and cloud storage connections. That makes it a practical choice for light outbound use, while anyone who needs regular receiving or a more complete business setup will need to move to a paid plan.

• Choose CocoFax if you want to send a few pages without providing a credit card before deciding whether to upgrade.
• Choose eFax if you need two-way faxing, stronger compliance options, or substantially more pages during the free period.

8. FaxDrop

FaxDrop strips online faxing down to the basics. There is no trial to cancel and no account needed just to send a short fax, which removes much of the friction found with subscription-based services. The tradeoff is that the free allowance is small and focused entirely on outbound faxing, making FaxDrop most useful only for infrequent, simple transmissions.

• Choose FaxDrop if you only send an occasional short fax and want to do it without creating an account or entering payment information.
• Choose eFax if faxing is an ongoing need and you want receiving, a dedicated number, and a much higher page allowance.

9. FaxZero

FaxZero is designed for speed and simplicity rather than for managing an ongoing fax account. You can send a short fax without registering, which makes it especially useful when you need to get a document out quickly and do not want to create another account. The tradeoffs are the lack of receiving, lower transmission priority, and branding on free faxes, so it is best viewed as a convenience tool rather than a professional fax solution.

• Choose FaxZero if you need to send a short fax immediately and do not want to register or provide a credit card.
• Choose eFax if you want a professional two-way fax service rather than an ad-supported, send-only tool.

10. GotFreeFax

GotFreeFax is built around quick, occasional faxing rather than an ongoing fax account. Users can send a small number of pages without registering or entering payment information, which makes it convenient for one-off needs. It does offer a way to receive faxes through a shared public number for viewing public inbound faxes online, but it explicitly advises against using it for personal or sensitive documents.

• Choose GotFreeFax if you occasionally need to send a short fax and want to avoid both account creation and payment information.
• Choose eFax if you need a private fax number, regular incoming faxes, or a service designed for ongoing business use.

11. FaxBurner

FaxBurner stands out because its free service is more useful for receiving than for sending. Users can get a temporary fax number for incoming documents, while outbound faxing is restricted to a very small lifetime allowance. That makes it a niche but useful option for someone who needs to receive a fax occasionally without paying for a permanent number, rather than someone looking for a regular two-way fax service.

• Choose FaxBurner if you only need to send one fax or receive a few and are OK with losing the fax number after 24 hours.
• Choose eFax if you need to send and receive more than a handful of pages, a dedicated fax number, or HIPAA-compliant faxing.

How to Evaluate and Choose the Right Fax Service Provider

When you are comparing fax services, here are a few key considerations to keep in mind.

• Reliability and speed: Check uptime guarantees, delivery confirmations, and transmission speed. Premium services offer higher reliability; free services may have peak-time delays.
• Security and compliance: Look for SSL/TLS encryption and regulatory compliance. Healthcare needs HIPAA with Business Associate Agreements. Financial institutions need SOC 2 Type II. Free services offer basic encryption but rarely meet regulatory requirements.
• Page limits: Compare daily limits versus lifetime totals. Renewable allowances provide better value.
• Integrations: Ensure support for your file types. Cloud integrations streamline workflows. Email-to-fax options add convenience.
• Support: Premium providers offer phone and live chat support. Free services typically provide limited support.

Experience Professional Free Faxing with eFax

Not all free faxing is created equal. While basic free services limit you to 5-10 pages with minimal features and uncertain delivery, eFax’s 7-day free trial provides up to 200 pages of professional-grade faxing with all the features you need:

• Military-Grade Security: 256-bit encryption for every document
• Premium Features: Mobile apps, email-to-fax, cloud integration, e-signatures
• Dedicated Fax Number: Real number for receiving, not temporary 24-hour numbers
• Guaranteed Delivery: Confirmations and audit trails for peace of mind
• Quality Support: Real help when you need it
