Monthly plans typically range from $9 to $40, depending on the number of pages, users, and premium features.
This article rounds up the best online fax services and breaks down their key features to help you identify which one fits your business needs best.

I compiled these top services and developed a detailed scoring rubric to evaluate each one fairly and consistently. This process allowed me to compare providers side by side and highlight the ones that truly deliver value based on real-world business needs.

Why I chose Fax.Plus
If your business has advanced faxing needs or handles sensitive information, Fax.Plus delivers a comprehensive digital fax solution designed for both functionality and security. The platform enhances fax quality by removing background shadows and sharpening text for improved legibility. You also get several customization tools, such as editable fax headers, personalized cover pages, flexible fax reception settings, and blacklisting options to block unwanted senders.
On the compliance side, Fax.Plus is fully audited to adhere to top-tier industry standards, including International Organization for Standardization (ISO) and System and Organization Controls (SOC) 2. Its robust security infrastructure includes encrypted storage for fax archives, transport layer security (TLS) to protect data in transit, and the use of a content delivery network (CDN) to safeguard against distributed cyberattacks.
That said, the entry-level plan comes with a major limitation: it only lets you send faxes. If you’re looking for a more cost-effective option that supports both sending and receiving, Nextiva vFax is a strong alternative. It offers two-way faxing at a lower price point, making it a smart pick for budget-conscious users who still need core capabilities.
- Confirmation report: Get a printable confirmation report after each fax, showing delivery status, date, time, page count, a preview, and a QR code for verification.
- Online signature: Easily sign documents using Sign.Plus with your Fax.Plus login, and access advanced electronic signature tools.
- Fax header: Automatically include key details like date, time, fax numbers, page count, and a custom header on every fax.
- Extension dialing: Send faxes to extension numbers by entering the main number, followed by an asterisk and the extension.
- Scheduled faxing: Set your faxes to send automatically at a specific date and time for better control and timing.

Why I chose eFax
If your business regularly sends large files to multiple recipients, eFax is a solid choice for high-volume faxing. You can send large files up to 3GB using a secure downloadable link. These files can be delivered to as many as 20 email addresses at once. With a paid plan, you can send up to 75 large-file faxes each month, which is ideal for teams that frequently share detailed reports, contracts, or media-heavy documents.
eFax also makes it easy to stay organized. Every fax you send is automatically archived in the cloud, and the searchable archive feature helps you quickly locate old faxes when you need them.
While eFax runs a $5 introductory offer for new users, the regular monthly price jumps to $18.99, which may be too steep for small businesses that fax only occasionally. If you’re looking for a more affordable option, Nextiva offers similar core features starting at just $9.95 for up to 500 pages per month.
- Secure online storage: You get built-in secure cloud storage with every eFax plan, making it easy to access, organize, and track your fax history when needed.
- Searchable faxes: eFax’s searchable storage lets you quickly locate old faxes without digging through folders, a huge time-saver when managing high volumes.
- Admin management portal: With the admin portal, you can control user access, manage contacts, monitor activity, and centralize your faxing operations from one dashboard.
- Fax from multiple email addresses: You can send faxes from up to five email addresses simultaneously. This lets you coordinate across teams or departments using shared resources.
- Fax API: The eFax application programming interface (API) makes it simple to embed faxing into your existing business workflows, whether you’re working with customer relationship management (CRM) systems, electronic health records (EHRs), or back-office systems.

Why I chose Dropbox Fax
Most online fax providers offer international faxing with competitive rates, but Dropbox Fax simplifies things by including global coverage in your monthly page bundle. You can fax to over 70 countries without worrying about extra charges. Depending on the location, faxing may use more than one credit; for instance, sending a fax to Switzerland uses two page credits per page.
Dropbox Fax also has one of the more generous free plans out there. You get five pages to start, and you can earn extra pages by completing simple tasks like sharing the service on Facebook, tweeting about it, importing your Gmail contacts, or inviting friends.
One limitation, though, is the lack of customizable cover sheets. If your business relies on branded or personalized fax covers, this could be a drawback. In that case, iFax is a better fit, as it gives you access to a wide selection of cover sheet templates and customization tools to match your professional look.
- International coverage: You can fax to the US, Canada, and the U.K. without long-distance charges. Dropbox counts pages, not minutes, so costs stay predictable.
- Cloud storage: Easily send, receive, and manage faxes in the cloud with built-in integrations for Google Drive, Dropbox, Box, OneDrive, and Evernote.
- Fax number porting: Keep your existing fax number by porting it to Dropbox Fax, so clients can continue sending faxes without disruption.
- Send and receive faxes: Just enter a fax number to send a document, and when someone faxes you, it arrives in your inbox as a PDF.
- Sign documents and fill out forms: Upload nearly any file type, add your signature, or fill out forms directly in your browser, then send the completed document via fax or email.

- Free plan: Gives you standard online faxing tools with over five free pages, support for one sender, international faxing, cloud integration, and secure cloud storage.
- Home Office: Steps things up with over 300 monthly fax pages, access for five users, and features like email-to-fax, receive fax, and multiple recipient support.
- Professional: With 500+ monthly fax pages and up to 10 users, the Professional plan adds fax number porting to its full suite of cloud and e-signature tools.
- Small Business: Built for high-volume users and includes 1,000+ fax pages per month, 20 senders, full international coverage, and every premium fax feature Dropbox offers.

Why I chose SRFax
Many online faxing services offer Health Insurance Portability and Accountability Act (HIPAA) compliance to support healthcare professionals, but SRFax goes a step further by delivering fax solutions specifically designed for the healthcare industry. It uses strong encryption and an authentication system to safeguard sensitive files, and you can request a signed Business Associate Agreement (BAA) to formalize its commitment to protecting patient data.
SRFax also offers standard plans for non-healthcare users, which include helpful features like fax scheduling, unlimited storage, and bulk sending to up to 50 recipients. However, its interface can feel outdated and clunky, especially if you’re new to online faxing. If ease of use is a priority, Dropbox Fax offers a much more intuitive experience with a clean, familiar layout across its web and app platforms.
- Secure downloader: Installing this program lets you automatically download received faxes to a specific folder on your computer for fast, secure access.
- Fax numbers: Offers local and toll-free internet fax numbers that work across all 50 US states and Canada.
- Printer driver: Fax directly from any application without the need for your login credentials.
- Client for Mac: SRFax’s Mac-compatible desktop client lets you send and receive faxes without logging in using a lightweight Java-based app.
- Optical character recognition (OCR): Converts scanned fax documents into searchable, editable text to streamline digital processing.

SRFax’s Standard plans include 200 to 800 combined pages per month, unlimited outbound users, unlimited storage, and optional add-on fax numbers. All plans also come with consolidated billing, secure encryption, and support for multiple users with their own fax numbers.

Cons
- Fax features are locked at the most expensive plan
- The first two plans don’t include faxing features
Why I chose iFax
If your business frequently deals with faxes and needs a more organized way to handle them, iFax is worth exploring. It offers a centralized fax inbox where you and your team can view, manage, and store incoming and outgoing faxes in one place. Within the inbox, you can set up folders, apply search filters, and even sync with cloud storage platforms for easier document management.
What really sets iFax apart is its one-time faxing option. You can send files or scan and fax documents without committing to a monthly plan. This pay-per-fax service starts at $1.99 per page and includes mobile and desktop access, encrypted fax history, and cloud-based storage.
That said, iFax keeps many of its advanced features locked behind its top-tier plan. Of its three monthly plans, only the highest-priced option gives you access to the full suite of faxing tools. If you’re looking for an all-in-one solution with features like e-signatures and searchable fax storage included across all plans, eFax delivers more flexibility out of the box.
- Shared team inbox: Faxes can be routed to a shared team inbox or specific users, so your team always knows what’s next and no important file slips through the cracks.
- Fax automation: Use IF/THEN logic to automate your fax workflow, label, route, or forward faxes automatically to save time and eliminate manual steps.
- Fax broadcast: Send a single fax to multiple recipients from any device, protected by military-grade encryption to keep your data and contacts secure.
- Customizable fields: Personalize every fax with customizable fields, giving your recipients a more tailored and professional communication experience.
- One-time faxing: Skip the subscription and send a fax on demand for as little as $1.99 per page, no contracts or no hidden fees.

- Basic: Includes 200 pages per month and outgoing faxing
- Plus: Adds HIPAA and SOC 2 compliance, ability to send and receive faxes, and multi-platform access (iOS, Android, Windows, and Mac)
- Pro: Provides 1,000 pages per month along with advanced features like scheduled faxes, fax forwarding, team collaboration tools, eSign support, cloud storage integration, and full API access.

- Failed faxes do not count as your usage
- Connect Nextiva to your old fax machine
Cons

Why I chose Nextiva vFAX
Nextiva, a well-known cloud communications provider, offers a dedicated online fax service through Nextiva vFAX. What sets it apart is its unique fax bridge, which allows you to keep using your traditional fax machine while still benefiting from virtual faxing. Simply connect the bridge to your device, and you’re ready to send and receive faxes without switching fully to digital.
I also like that Nextiva offers one of the most affordable plans on the market. Its entry-level tier includes 500 pages per month, bringing excellent value for money. If you’re looking for more functionality, you can upgrade to a full Nextiva plan that combines digital faxing with a full suite of VoIP phone features.
That said, Nextiva focuses on core faxing tasks like sending and receiving documents, and lacks custom features like annotations. If your team needs those capabilities, I recommend Dropbox Fax, which includes tools like e-signatures and in-document edits at no extra cost.
- Email-to-fax and fax-to-email: You can send and receive faxes directly from your email, with incoming faxes delivered as PDFs to your inbox
- Online fax portal: Nextiva’s secure web portal gives you 24/7 access to view, send, and manage your faxes from any device with internet access.
- HIPAA-compliant faxing: For healthcare and other regulated industries, Nextiva vFAX offers HIPAA-compliant plans with secure transmission and privacy safeguards.
- Fax number porting: You can transfer your existing fax number to Nextiva without changing how your clients send you documents.
- Unlimited fax storage: All your sent and received faxes are stored securely online, giving you unlimited access and easy retrieval when needed.
| Plans | Essential | Professional | HIPAA Compliant |
|---|---|---|---|
| Monthly | $9.95 | $18.95 | Custom |
| Annually | $7.95 | $13.95 | Custom |
| Number of pages per month | 500 pages | 1,000 pages | Custom |
Nextiva vFAX offers 500 to 1,000 pages per month across its Essential and Professional plans, plus a HIPAA-compliant option for secure virtual faxing in regulated industries.
How to choose the right online fax service
Choosing the best online fax company depends on your business needs, file volume, and how often you send or receive sensitive documents. Look for a provider that balances features, ease of use, and affordability because the right platform should offer convenience while maintaining high security standards.
When choosing an online fax service, I recommend focusing on the following key buying factors:
- Security and compliance: Look for HIPAA or SOC 2 compliance if you’re handling sensitive or regulated information.
- File size and format support: Choose a service that handles large files and supports multiple formats like PDF, DOC, and JPG.
- Sending and receiving options: Email-to-fax, mobile apps, and scheduled faxing improve workflow and accessibility.
- Cloud and app integrations: Integration with platforms like Dropbox, Google Drive, or Slack helps streamline document management.
- Pricing and page limits: Compare monthly page caps, overage fees, and free plan availability to avoid hidden costs.
Among all the best online faxing services I evaluated, I chose Fax.Plus as my top pick because it offers a great mix of user-friendly tools, scalability, and enterprise-grade features. It supports cloud storage integrations, confirmation reports, and free faxing for users on a tight budget. Most importantly, it delivers strong security with HIPAA compliance and advanced encryption for peace of mind.
