Fax.Plus is the best online fax service for most individuals and small businesses. Its published Basic plan costs $6.99 per month for 200 pages, one fax number, email-to-fax, mobile access, unlimited fax storage, and a $0.10 overage rate. It is not the right universal choice, however: Dropbox Fax is better for cloud-document workflows, SRFax is stronger for healthcare value, eFax suits established international users, and RingCentral makes more sense when fax must live alongside business phone, messaging, and meetings.

This guide ranks the leading services by use case rather than pretending that one provider wins for every budget, fax volume, country, or compliance requirement. Disclosure: this article may contain referral links. They do not change the price you pay or our recommendations.

Quick verdict

• Best overall for most people: Fax.Plus—a low starting price, 200 included pages, one number, email and mobile workflows, and clear overage pricing.
• Best for cloud documents, editing, and signatures: Dropbox Fax—especially if your files already live in Dropbox, Google Drive, Box, OneDrive, or Evernote.
• Best for established businesses and international faxing: eFax—with personal, business, and enterprise product families, apps, searchable storage, and international plans.
• Best healthcare value: SRFax—its Healthcare Basic Plus plan publishes 800 combined sent-and-received pages for $22.95 per month and includes a BAA.
• Best for unified communications: RingCentral—fax is part of RingEX and can be used through web, desktop, email, mobile, and API workflows.
• Best for a few outbound pages: Dropbox Fax or the Fax.Plus free allowance, although receiving faxes normally requires a paid account or dedicated number.

Important: do not choose a provider solely because it says “HIPAA compliant.” For protected health information, verify the exact plan, required safeguards, and a signed Business Associate Agreement before sending anything.

Online fax services compared

How to read this table: page allowances are not perfectly comparable. Some providers describe outbound pages, some describe a plan allowance without making the direction clear in the short pricing summary, and SRFax explicitly combines sent and received pages. Confirm how your chosen plan counts pages, covers, retries, and inbound traffic before comparing monthly costs.

1. Fax.Plus: best overall for most individuals and small businesses

Fax.Plus plans offer the clearest starting point for ordinary administrative faxing: a small business or individual can pay $6.99 per month for 200 pages, one fax number, one member, email-to-fax, mobile access, unlimited fax storage, and a $0.10 rate for pages beyond the allowance.

That combination is compelling when you send faxes regularly but do not need a full communications platform. You can work from email, a browser, or a phone instead of maintaining a physical fax machine, telephone line, toner, and paper supply. The included number also makes the paid plan more practical than a one-off sending service when customers, insurers, agencies, or vendors need to fax you back.

Fax.Plus also has a free plan with 10 pages in total. That is useful for a small one-time outbound job, but it should not be treated as a full inbound fax solution. If you need to publish a number and receive documents, budget for a paid tier.

Where Fax.Plus stops being the obvious choice

The Basic plan is aimed at light-to-moderate use. The published plan information limits a single fax to 60 pages, and the plan does not provide the higher-end administration and compliance features that regulated organizations may need. Premium and higher tiers add features such as number porting, toll-free numbers, team administration, Slack, API access, SSO, and data residency. Fax.Plus identifies HIPAA support with a BAA at the Enterprise level; do not assume that the $6.99 plan carries the same contractual protection.

Choose it if: you need a recurring number, send up to roughly a few hundred pages per month, want transparent pricing, and do not need a signed BAA on the entry tier.

Look elsewhere if: your workflow revolves around cloud-document editing, you need a healthcare plan with a clearly published BAA at a lower volume tier, or fax is only one part of a larger phone and collaboration system.

2. Dropbox Fax: best for cloud documents and signatures

Dropbox Fax, formerly HelloFax, is the most natural choice when documents already live in a cloud storage account. It can send and receive faxes through the web and email, deliver incoming faxes as PDFs, and connect with Dropbox, Google Drive, Box, OneDrive, and Evernote.

The workflow is more document-oriented than machine-oriented: upload or select a file, edit it or add text and signature fields, enter the recipient, and send. That is useful for forms that need a signature or last-minute completion before transmission. It also reduces the download-upload cycle common with generic fax portals.

Pricing and inbound limitation

Dropbox Fax provides five free pages. Its published pay-as-you-go path charges $0.99 for a send of up to 10 pages after the free allowance, followed by $0.20 for each additional page in that flow. Paid plans publish a lower $0.05 overage rate per page sent or received.

The important limitation is that paid accounts are needed for inbound faxing. The free allowance is therefore best for sending a short document, not for replacing a business fax number. If you already have a public fax number, number porting requires a Professional or Small Business plan; ask about eligibility and timing before cancelling your old service.

Choose it if: Dropbox, Google Drive, Box, OneDrive, or Evernote is central to your work, and editing or signing a document is as important as transmitting it.

Look elsewhere if: you want the lowest predictable monthly cost for hundreds of pages, need a healthcare-specific plan with an explicitly published BAA, or need a broad international footprint.

3. eFax: best for established international workflows

eFax plans are worth considering when fax is already an established business process, especially when users need email-to-fax, searchable storage, electronic signatures, desktop software, mobile apps, and a choice of local or toll-free numbers.

eFax publishes several product families, so its pricing requires more care than a single-plan comparison suggests. The public pricing information identifies a Personal allowance of 200 pages to the United States and Canada and a Business allowance of 500 pages to 51 countries. The stated overage rates are $0.10 per page for Personal and $0.07 per page for Business. The pricing page advertises plans starting at $14.99, while a separate promotion shows eFax Plus with a regular price of $18.99 and a temporary introductory offer.

Those figures should be treated as plan-specific, not as a universal eFax price. Monthly versus annual billing, promotions, country, number type, legacy plans, and enterprise quotes can change the amount shown at checkout. Confirm the exact selected plan and its included destinations before ordering.

Compliance and enterprise considerations

eFax Business and Corporate materials identify BAA availability. Corporate materials also identify HITRUST certification, API access, and healthcare interoperability capabilities. These are meaningful enterprise signals, but the buyer still needs to confirm which product family, plan, contract, and administrative controls apply. A promotional consumer plan should not be treated as equivalent to a negotiated corporate deployment.

Choose it if: you need a mature service with mobile and desktop access, searchable archives, international destinations, or a path toward enterprise integration.

Look elsewhere if: you want a single transparent entry-level plan, primarily need cloud-drive editing, or need U.S.-and-Canada healthcare pricing that is easy to calculate.

4. SRFax: best healthcare value and transparent high-volume plans

SRFax healthcare is the strongest value-oriented option in this comparison for a healthcare organization that needs a BAA and more volume than a basic consumer plan provides. Its published Healthcare Basic Plus plan costs $22.95 per month for 800 combined sent-and-received pages, with additional pages priced at $0.05 each.

Because the allowance is combined, a practice can reason about its total fax traffic rather than maintaining separate sent and received buckets. For example, 900 total pages would be 100 pages above the published allowance, or $27.95 before taxes and any other applicable charges, assuming the same plan and overage rules apply. That is an illustration of the published allowance—not a guarantee of a final invoice.

SRFax healthcare plans also publish multiple users, unlimited authorized email addresses, online storage, API access, and email, web, and mobile workflows. Larger published plans reach 20,000 pages per month. The service states that it signs a BAA and is available in the United States and Canada. Additional numbers and number porting are also advertised.

What to verify before sending protected health information

A BAA is necessary for a covered workflow, but it is not the only procurement question. Confirm that the exact account and plan are covered, identify who can access stored faxes, review retention and deletion controls, and determine whether your organization has configuration or logging obligations. Test the workflow with non-sensitive documents first.

Choose it if: you are a U.S. or Canadian healthcare practice or organization, need a BAA, and want a transparent combined-page allowance with healthcare-specific plans.

Look elsewhere if: you need a destination outside the stated service region, want a general-purpose consumer plan, or already use RingCentral for all communications and prefer one vendor.

5. RingCentral: best when fax belongs inside unified communications

RingCentral fax is not primarily a bargain fax mailbox. It is fax inside RingEX, RingCentral’s broader communications platform. Users can send and receive through the web, desktop, email, and mobile applications, with features such as scheduling, cover pages, multiple attachments, cloud integrations, and an API.

This makes RingCentral a logical candidate for a company already consolidating phone service, messaging, meetings, and fax. It can also be attractive for developers that want fax capabilities exposed through an existing communications API. RingCentral developer documentation states that the Fax API is included with RingEX plans, supports unlimited U.S./Canada faxing for a local number, and supports international faxing to more than 190 countries.

The trade-off is price transparency. Exact consumer-facing fax pricing is not consistently exposed on public product pages, so a buyer should obtain a current quote and confirm what is included in the specific RingEX package. Do not compare a sales-led unified-communications quote directly with a $6.99 standalone fax subscription without including the value of the other services—or the cost of services you do not need.

RingCentral advertises HIPAA-oriented faxing and compliance capabilities, but regulated buyers should verify the applicable plan, contractual terms, configuration requirements, and BAA during procurement.

How to choose the right online fax service

For occasional one-off faxing

Start with the free allowances rather than paying for a permanent fax number. Dropbox Fax provides five free pages, while Fax.Plus provides 10 free pages in total. Dropbox’s published pay-as-you-go path can be useful when the document exceeds the free allowance but you do not expect recurring work.

Before relying on a free account, answer one question: Do you need to receive a reply? Sending a document once and receiving faxes regularly are different requirements. A recurring inbound number generally requires a paid account.

For regular individual or small-business faxing

Fax.Plus Basic is the strongest starting point based on the published price-to-page allowance: $6.99 per month for 200 pages and one number. It is a good fit for routine administrative work such as vendor forms, contracts, government paperwork, and occasional customer documents.

Check whether your actual usage includes inbound pages, whether any single fax exceeds 60 pages, and whether you need multiple users or number porting. If the answer to any of those is yes, compare a higher Fax.Plus tier with Dropbox Fax, eFax, or SRFax rather than choosing Basic automatically.

For cloud storage, editing, and signatures

Dropbox Fax is the clearest fit when the source file is already in a cloud drive or needs fields added before transmission. Its ability to edit documents and add signature or text fields can eliminate a separate print-sign-scan cycle. It is particularly attractive to small teams that treat faxes as part of a document workflow rather than as a standalone communications channel.

For healthcare and regulated information

Faxing itself is not required by HIPAA. The question is whether the provider and your configuration satisfy the safeguards and contractual obligations applicable to your organization.

Before sending protected health information, require all of the following:

1. Exact-plan confirmation: identify the plan name, not just the provider’s general compliance page.
2. A signed BAA: obtain it before transmitting regulated information.
3. Access controls: determine which users can send, receive, search, download, or delete faxes.
4. Retention and deletion terms: establish how long stored faxes remain available and how your organization can remove them.
5. Destination controls: verify the recipient number and establish a process for correcting misdirected faxes.
6. Testing and documentation: test with non-sensitive files and document the approved workflow.

SRFax is the most straightforward value candidate because it publishes healthcare plans and explicit BAA language. eFax identifies BAA availability on Business and Corporate offerings. Fax.Plus identifies HIPAA/BAA support at Enterprise. RingCentral advertises HIPAA-oriented faxing, but its exact plan and contractual coverage must be confirmed. None of those statements means every tier is interchangeable.

For international faxing

“International” is not a sufficient comparison. Destination coverage, country-specific rates, local versus toll-free number availability, and the direction of the fax can all matter.

• eFax Business: publishes coverage to 51 countries on the cited plan.
• RingCentral: states that its platform supports more than 190 countries.
• Fax.Plus: states in service materials that it supports more than 180 countries.

Ask the provider to confirm the exact destination country, number type, and rate for your account. A service that supports “more than 180 countries” may still be unsuitable for one particular destination or plan.

For number porting and inbound continuity

Porting a number is more than checking a feature box. Confirm eligibility, required documents, estimated lead time, downtime protections, and whether the service can keep your old number active while the transfer completes.

• Fax.Plus: porting is listed for Premium and higher tiers.
• Dropbox Fax: porting requests require a Professional or Small Business plan.
• eFax: offers local and toll-free numbers and says existing numbers can be transferred.
• SRFax: advertises number porting.
• RingCentral: confirm current eligibility and timing as part of the quote.

Do not cancel the old fax service until the ported number is live, inbound delivery has been tested, and important senders have been notified if the fax address or cover-sheet details change.

Understanding online fax costs

Included pages are not always equivalent

Providers may count sent pages, received pages, or both. SRFax Healthcare Basic Plus explicitly uses a combined 800-page allowance. Dropbox Fax publishes a $0.05 paid-plan overage for each page sent or received. Other providers may present an allowance in a way that requires checking the plan’s detailed terms.

Ask these questions before comparing plans:

• Are sent and received pages counted together?
• Does a cover sheet count as a page?
• Are failed transmissions or retries charged?
• Are international pages priced differently?
• Does the allowance reset monthly?
• What happens when you exceed it?
• Is there a maximum number of pages in one fax?

Calculate based on your real traffic

Separate your last few months of fax activity into outbound pages, inbound pages, destinations, number of users, and unusually long documents. A low monthly average can hide an expensive requirement if you need a permanent number, international delivery, multiple users, or a BAA.

For example, a person sending one 6-page document may be better served by a free or pay-as-you-go allowance. A small office sending 150 to 200 pages every month may get more predictable costs from Fax.Plus Basic. A healthcare practice with 800 combined pages may find SRFax easier to budget. A company already paying for RingEX may prefer integrated fax even if a standalone service has a lower sticker price.

Optional paper-to-digital accessory

Online fax does not require a scanner: documents created on a computer or phone can usually be uploaded directly. A scanner is useful only when your workflow begins with paper forms, signed pages, or mailed records. In that case, a portable document scanner can turn paper into a PDF before you upload it to the fax service.

Look for automatic document feeding, duplex scanning, searchable PDF support, and compatibility with your operating system if you process many pages. For occasional paperwork, a phone camera may be sufficient. Treat the scanner as an optional task-enabling accessory, not as a required part of online fax.

Online fax buying checklist

1. Define the direction: outbound only, inbound only, or both?
2. Count pages: include covers, attachments, received documents, and peak months.
3. Decide whether you need a permanent number: free sending allowances rarely replace an inbound business number.
4. Check your file workflow: email, browser, mobile, cloud drive, signatures, API, or all of them.
5. Confirm destinations: especially for international numbers, toll-free numbers, and number types.
6. Check porting: ask about eligibility, lead time, downtime, and temporary forwarding.
7. Verify compliance: identify the exact plan and obtain a BAA when required.
8. Review storage: understand search, export, retention, deletion, and user permissions.
9. Test before migration: send and receive non-sensitive test documents with every major destination.
10. Compare the complete price: include the subscription, overages, additional numbers, international charges, users, and annual-billing conditions.

Price-verification note

The prices and allowances in this guide were checked against provider-published information dated August 12, 2026. Online fax pricing can vary by country, billing frequency, promotions, number type, legacy account, and negotiated enterprise quote. Confirm the final checkout price and plan terms before subscribing.

No provider in this guide is called “the most reliable” because the available research establishes published features and pricing, not an independent delivery-rate test using a reproducible dataset. For important workflows, run your own test with the destinations and document types you actually use.

Frequently Asked Questions

What is the best online fax service for most small businesses?

Fax.Plus is the strongest general recommendation because its published Basic plan costs $6.99 per month for 200 pages, one number, email-to-fax, mobile access, and a $0.10 overage rate. Choose another service if you need cloud-document editing, a healthcare BAA on a specific lower-tier plan, or unified communications.

Can I receive faxes for free?

Usually not as a dependable business service. Dropbox Fax offers five free pages and Fax.Plus offers 10 free pages in total, but receiving faxes generally requires a paid account or dedicated fax number. Confirm inbound availability before giving anyone your fax number.

Which online fax service is best for HIPAA-related healthcare work?

SRFax is the clearest healthcare-value option because it publishes healthcare plans and explicit BAA support. eFax identifies BAA availability on Business and Corporate offerings, Fax.Plus identifies it at Enterprise, and RingCentral advertises HIPAA-oriented capabilities. In every case, verify the exact plan and obtain a signed BAA before transmitting protected health information.

Is eFax better than Fax.Plus?

It depends on the workflow. Fax.Plus is generally more compelling for a small business seeking a low-cost recurring plan with 200 included pages. eFax is more suitable when you need established international offerings, desktop and mobile apps, searchable storage, or an enterprise path. Compare the exact plans because eFax publishes multiple product families and promotions.

Can I keep my existing fax number when switching services?

Often, but eligibility and timing vary. Fax.Plus lists porting on Premium and higher tiers; Dropbox Fax requires Professional or Small Business; eFax and SRFax advertise number transfers. Ask about lead time, downtime protection, and required paperwork, and do not cancel the old service until inbound testing succeeds.

The Bottom Line

For most individuals and small businesses, start with Fax.Plus. Choose Dropbox Fax when cloud documents, editing, and signatures drive the workflow; eFax for established international or enterprise use; SRFax for healthcare value and a clearly published BAA; and RingCentral when fax belongs inside a broader RingEX communications deployment. Before subscribing, compare page-count rules, inbound access, porting, destination coverage, and the exact compliance contract—not just the headline monthly price.
