1. Municorn Fax: The Best Overall Way to Send Fax Online
Municorn Fax delivers the strongest all-around package for anyone asking “what is the best way to send fax online.” This service prioritizes document fidelity, unlimited sending and receiving on every tier, and HIPAA compliance as standard—no hidden upgrades required.
Why Municorn Fax Stands Out
Unlimited pages at every tier is the primary differentiator. At $9.99 per week, you receive unlimited fax sending and receiving with no page caps or surprise overage fees. Most competitors segment their pricing by page allowance, forcing users to decode tier structures and calculate costs. Municorn Fax eliminates this friction. The service covers 90+ countries at no extra charge, making it practical for global workflows.
Fax number flexibility includes the ability to select your preferred area code within the US and Canada, or port an existing fax number to preserve continuity. This matters for businesses that rely on recognized local numbers or must maintain established contact information.
Document quality is measurably superior on send. Test scans transmitted through Municorn Fax retain more light and detail compared to competing services, reducing the risk of illegible reproductions. This precision is especially critical in legal, medical, and financial sectors where document integrity is non-negotiable.
Security and HIPAA Compliance
Faxes are encrypted with AES-256 encryption at rest and TLS in transit. HIPAA compliance with a Business Associate Agreement (BAA) is included on every plan tier rather than gatekept behind premium pricing. Compliancy Group validates this compliance, and no additional fees apply to unlock security features.
User Experience and Support
The built-in scanner within the app performs competently enough that you likely won’t need a separate scanning application. You can retrieve documents from cloud storage, edit them, and send them from a single interface. In-app live chat support provides direct access to assistance. The service maintains strong ratings: 4.8 out of 5 stars across 364,000+ reviews on the App Store, with the Android version at 4.5 stars. Total downloads exceed 18 million across US territories.
When Municorn Fax May Not Be Ideal
If you send faxes only once or twice yearly, the unlimited subscription model costs more than pay-per-page alternatives that charge per fax rather than a flat rate. Very light users might save money with services offering true free tiers or one-off sending options.
2. eFax: Enterprise Admin Controls and Compliance
eFax prioritizes administrative oversight, making it a strong choice for organizations managing multiple teams or requiring strict compliance workflows. The service excels at role-based access control and audit trails, appealing to finance, legal, and healthcare environments.
Key Strengths
Advanced admin controls let you assign permissions, monitor fax activity, and enforce security policies across your organization. HIPAA compliance is supported. eFax integrates with common business applications, reducing manual data entry. Fax quality and delivery speed meet industry standards. The platform supports both web-based and email-based sending methods.
Pricing and Page Limits
Costs vary by plan tier, with pricing typically tied to page allowances rather than unlimited models. Calculate your monthly fax volume before committing to avoid surprise costs if you exceed plan limits.
3. Fax.Plus: Security-First and Compliance-Focused
Fax.Plus emphasizes encryption, regulatory compliance, and data residency control. If security is your primary concern over cost, this service aligns well with that priority.
Key Strengths
The platform offers HIPAA compliance and supports multiple encryption standards. You gain granular control over where your data is stored geographically. Interface simplicity balances security without sacrificing usability. Documentation and compliance resources are thorough.
Best Suited For
Healthcare providers, legal firms, and regulated industries prioritizing data sovereignty and audit-trail documentation.
4. iFax: Highly Configurable Solutions
iFax caters to users requiring custom workflows and detailed system configuration. This platform appeals to tech-savvy teams or enterprises needing API integrations and specialized automation rules.
Key Strengths
Extensive customization options, including routing rules, custom headers, and automated workflows. HIPAA compliance is available. Integration capabilities support enterprise systems. Fax quality is reliable across use cases.
Trade-offs
Setup complexity and configuration options can overwhelm casual users. This service rewards technical expertise but requires more onboarding time than simpler platforms.
5. RingCentral: High-Volume Faxing and Unified Communications
RingCentral bundles online faxing with voice, video, and messaging, making it ideal for organizations already using or considering a unified communications platform.
Key Strengths
Starting at $15 per month, faxing integrates seamlessly with voice and video features. HIPAA compliance is supported. Fax quality is professional. Page allowances vary by plan tier. The platform suits businesses managing high fax volumes who also need phone and meeting capabilities.
Best Suited For
Teams already invested in RingCentral voice services, or organizations seeking a single vendor for communications.
6. Dropbox Fax: Value and File Integration
Dropbox Fax (also known as HelloFax when accessed through Dropbox) provides accessible online faxing for users already relying on Dropbox file storage and collaboration.
Key Strengths
Seamless integration with Dropbox folders eliminates separate logins. HIPAA compliance is available. Pricing is competitive. The platform simplifies workflows for Dropbox-centric teams. Interface remains intuitive for casual users.
Trade-offs
If your team doesn’t use Dropbox, the file integration advantage disappears. Page limits and pricing tiers require comparison against standalone fax services.

Common Misconceptions About Online Faxing
Myth: Recipients with fax machines can’t receive your internet fax. Reality: Cloud fax services convert your documents into fax signals that any fax machine recognizes. The recipient sees a printed page—they can’t tell the difference.
Myth: Online fax is less secure than physical machines. Reality: AES-256 encryption and secure transmission exceed the security of unsecured fax trays or physical paper storage. HIPAA-compliant services meet healthcare standards.
Myth: All online fax services are essentially identical. Reality: Page allowances, pricing models, fax quality, compliance certifications, and customer support vary significantly. Document fidelity differences are measurable.
FAQ: Best Way to Send Fax Online
Can you send a fax through the internet?
Yes. Cloud fax services convert your digital documents into fax-compatible signals and transmit them through the internet to any fax number (or email, if the recipient uses an online fax service). The recipient receives a printed page or digital file—they can’t tell whether you used a physical machine or internet service. No fax machine or phone line is required on your end.
Can I send a fax online for free?
Several platforms offer limited free sending. Typical free tiers allow 5 faxes per day with an advertisement on the cover page and up to 3 pages per fax. For unlimited sending, paid subscriptions apply. Municorn Fax offers a free test fax to try the service. Occasional users may save money with free-tier services, while high-volume senders benefit from unlimited plans.
Is eFax still free?
eFax no longer offers a completely free tier. The service operates on paid subscription plans with varying page allowances. Some competitors (like FaxZero or FaxBetter) continue offering free limited faxing, but eFax focuses on premium paid models.
Can I send a fax from Gmail for free?
Gmail doesn’t have a native fax feature. However, you can send faxes through online fax services by forwarding documents to a service email address (format: [fax-number]@[service-domain].com). You’ll need an active account with an online fax provider. Some providers include this functionality in paid plans, while others integrate directly with email clients.
What makes an online fax service HIPAA compliant?
HIPAA compliance requires encryption in transit (TLS) and at rest (AES-256), a signed Business Associate Agreement (BAA), access controls, audit logging, and third-party validation. Services like Municorn Fax, eFax, Fax.Plus, and iFax meet these standards. Always verify compliance with your provider and request a BAA before transmitting protected health information.
How does online faxing work technically?
You upload or attach a document to an online fax service through an app, website, or email. The service converts your PDF or image into a fax signal (T.30 protocol) and transmits it via the internet to your recipient’s fax machine. The fax machine decodes the signal and prints the document. If both parties use online fax services, delivery can be direct email-to-email without involving traditional machines.
