- 7 tools compared: Fax.Plus, SRFax, iFax, eFax, FaxBurner, RingCentral Fax, Fax Pigeon
- Fax.Plus (best for: Small businesses that want cheap, clearly tiered plans): From $6.99/mo (annual billing)
- SRFax (best for: Healthcare offices, including Canadian practices): Healthcare Lite $12.60/mo
- iFax (best for: Mobile-first users and teams that want desktop and phone apps): Basic $12.49/mo
- eFax (best for: Teams that want the best-known name in online fax): Plus from EUR 7.99/mo (EU site)
Short answer: Fax.Plus is the best online fax service for most small businesses, with clear page-based plans from $6.99 a month on annual billing. If you handle patient data, SRFax sells dedicated healthcare plans with HIPAA and Canadian PHIPA coverage. FaxBurner is the free option for the occasional one-off fax. Here is the full breakdown.
Faxing is still the way many banks, clinics, insurers, landlords and agencies want a signed document delivered. The good news is that you do not need a machine or a phone line for it. An online fax service gives you a fax number, sends and receives from a browser or your email, and files every fax as a PDF.
The differences that matter are not the features, which are nearly identical. They are three questions. How many pages a month do you really send and receive? Do you handle health information, which means you need a signed business associate agreement (BAA) and not just a "secure" label? And do you want a subscription at all, or just a way to send one fax?
This guide compares 7 services on those questions. Prices were read on each vendor's own pricing page on October 22, 2026, in USD unless stated. Where a vendor does not publish a price I say pricing on request rather than guess.

Fax.Plus: the clearest tiers for small teams
Fax.Plus is the one I'd start with for most small businesses. The plan ladder is easy to read: pick the page allowance that matches your month and you are done. It covers email-to-fax, a mobile app, unlimited fax storage and fax logs you can export to CSV, and teams can share a plan once they move up to Business.
Who it's for: Small businesses that want cheap, clearly tiered plans.
The easy default for small businesses that fax a few hundred pages a month. HIPAA with a BAA sits only on the Enterprise plan, so healthcare teams should look at SRFax below.
Plans are billed annually at a lower monthly rate. Basic is $6.99 a month ($83.99 a year) for 200 pages and one fax number. Premium is $13.99 a month ($167.99 a year) for 500 pages and adds toll-free numbers and number porting. Business is $27.99 a month ($335.99 a year) for 1,000 pages, multiple fax numbers and five members. Enterprise lists $79.99 a month on annual billing, or from $99.99 on monthly billing, for 4,000 pages. Extra pages cost $0.10 on Basic, $0.07 on Premium and $0.05 on Business, per Fax.Plus's pricing page.
The standout: Page allowances that step up cleanly, so you can match a plan to your real volume instead of guessing. Pay for 200 pages and only pay more when your month demands it.
The catch: HIPAA compliance with a BAA is available on the Enterprise plan only. If you handle patient data, that turns a $6.99 service into an $79.99 one.
SRFax: HIPAA and PHIPA plans for healthcare offices
SRFax is the service to look at if you run a healthcare office, especially in Canada. It sells dedicated healthcare plans, says its encryption covers U.S. HIPAA and Canadian PHIPA guidelines, and offers email-to-fax, a web portal and an API.
Who it's for: Healthcare offices, including Canadian practices.
A solid fit for healthcare offices that want a long-running provider with HIPAA and PHIPA coverage and a published price ladder. It costs more than the newer low-cost options for the same 200 pages.
The healthcare plans are priced by monthly pages, sent and received combined. Lite is $12.60 a month ($10.70 a month if you pay $128.40 a year) for 200 pages. Basic is $16.05 for 500 pages, Standard is $41.35 for 1,500, and Professional is $137.90 for 5,000, all monthly, with 15% off on annual billing. Extra pages are $0.05 and additional fax numbers are $4.95 each, per SRFax's healthcare plans. Standard business plans are priced on its plans page.
The standout: Healthcare-specific plans with a published page ladder, from 200 pages up to 20,000, plus Canadian PHIPA coverage that most U.S. services do not mention.
The catch: Even on annual billing, the entry plan is $10.70 for 200 pages, against $6.99 at Fax.Plus.
iFax: polished apps on every platform
iFax puts the app first. It ships iOS, Android, Windows and Mac apps, plus email-to-fax, one-time faxes, fax broadcast, contacts and a programmable fax API. It markets HIPAA-compliant faxing, and there is a free way to start, so you can send a test fax before you pay.
Who it's for: Mobile-first users and teams that want desktop and phone apps.
A good fit if you want a polished app on every device. At $12.49 for 200 pages it costs about double the cheapest options.
Basic is listed at $12.49 a month for 200 pages. Plus is $24.99 a month for 500 pages and one fax number. A Pro plan is marked Most Popular and Enterprise is volume pricing through sales, per iFax's pricing page. Check the Pro price on that page before you buy.
The standout: Native apps on every platform with the same account, which suits people who fax from a phone as often as from a desk.
The catch: It costs about double Fax.Plus for 200 pages, and Enterprise is quote-based.
eFax: the household name, with prices that vary by country
eFax is the name most people recognise, and for a recipient on the other end of a fax, a familiar sender helps. It offers Plus and Pro plans, each with a free trial.
Who it's for: Teams that want the best-known name in online fax.
Worth it if brand familiarity matters to the people you fax. Page allowances are small, so price the plan against your real volume first.
Prices depend on your country. eFax's European pricing page lists Plus at EUR 7.99 a month for 30 pages sent and 30 received, and Pro at EUR 10.99 a month for 150 pages each way, with annual billing at EUR 79.90 and EUR 109.90 (excluding VAT). Both come with a free trial. For U.S. prices, open eFax's pricing page from a U.S. connection, because the figure shown depends on your location.
The standout: The name. It is the brand most people already know, which can help when you fax people you have not faxed before.
The catch: The included page counts are small for the money, and the price you see depends on where you browse from, so compare carefully.
FaxBurner: a free disposable number for one-off sends
FaxBurner is for the person who needs to fax once in a while and does not want a subscription. Sign up with an email, get a free fax number that lasts 24 hours, and send. The paid plans keep a permanent toll-free number and raise the limits.
Who it's for: Occasional faxing, one-off sends and testing.
The easy pick for an occasional fax. Its pricing page makes no HIPAA claim, so keep regulated documents on a service that offers a BAA.
The free plan gives a disposable number that lasts 24 hours, with 5 pages sent in total and 25 pages received a month. Professional is $14.95 a month for a permanent toll-free number and 500 pages in and out. Premier is $24.95 a month for 2,000 pages in and out, per FaxBurner's pricing. It supports faxing within North America.
The standout: A free plan that needs no card, which makes it the lowest-friction way to send a single fax.
The catch: Its pricing page does not mention HIPAA or a BAA, so do not use it for patient data without asking. The free plan sends only 5 pages in total.
RingCentral Fax: online fax built into the phone platform
RingCentral Fax is not a standalone fax tool. RingCentral builds online faxing into RingEX, its AI-powered cloud platform that unifies messaging, video and phone, so the case for it is having fax next to the rest of your communications. If you already run RingCentral, that is the simplest path.
Who it's for: Companies already on RingCentral's phone system.
Right for companies already on RingCentral. If fax is your only need, a dedicated service is the cheaper route.
Pricing on request. RingCentral does not publish a standalone fax price; fax comes with RingEX, and plan prices are on RingCentral's plans page.
The standout: One vendor for phone, messaging, video and fax.
The catch: Paying for a full phone platform only to get fax makes no sense. If fax is all you need, a dedicated service costs far less.
Fax Pigeon: a signed BAA on every plan
Fax Pigeon is built around one idea: every plan, including the free first fax, runs under a signed BAA. You get your own fax number, unlimited people on the account, AI summaries of incoming faxes, e-signatures with delivery proof, and the ability to fax from your email. At $4.99 a month billed annually ($5.99 month to month) it undercuts both SRFax's healthcare Lite ($10.70 on annual billing) and the Fax.Plus tier that includes a BAA ($79.99), which is the whole question for a clinic, a pharmacy or a small billing office.
Who it's for: Practices and small teams that need a BAA without an enterprise price.
The pick for practices and small teams that need a signed BAA at a small-business price. It is a less established name than the incumbents, so confirm your recipients are comfortable with it before you move your number.
Six plans, all with every feature. Month to month, Basic is $5.99 a month for 200 pages, Standard $11.99 for 500, Plus $17.99 for 1,000, Pro $33.99 for 2,000, Premium $59.99 for 5,000 and Max $191.99 for 10,000. Billed annually, the same plans come to $4.99, $9.99, $16.99, $29.99, $49.99 and $159.99 a month. Extra pages run from 10 cents on Basic down to 2 cents on Max. Your first fax is free, up to 10 pages, with no card. Moving your existing number over is free on paid plans, per Fax Pigeon's pricing page.
The standout: The BAA is not an upsell. It is included on every plan, the free fax too, and so are unlimited users, so the price does not climb with headcount.
The catch: It is a less established name than eFax or RingCentral, so check that the people you fax are comfortable receiving from it. Overage pages are billed on a separate invoice.
How to choose
Start with the data you send, not the feature list.
- You handle patient or other regulated data. You need a signed BAA. SRFax sells dedicated healthcare plans, Fax Pigeon includes a BAA on every plan, and Fax.Plus offers a BAA on Enterprise only. FaxBurner's pricing page makes no HIPAA claim.
- You are a small business with steady volume. Fax.Plus. Match the plan to the pages you really send and receive in a month, because every service here prices by page allowance.
- You fax once a quarter. Use FaxBurner's free plan.
- You live in your phone. iFax has apps on iOS, Android, Windows and Mac.
- You already run RingCentral. Its online fax is part of RingEX, so start there.
Subscription or pay as you go? Every paid plan here is a monthly or annual subscription with a page allowance, and extra pages are billed per page (SRFax 5 cents, Fax.Plus 3 to 10 cents depending on plan). For a single fax, the free options above beat any subscription.

How we chose these services
I picked widely used online fax services that publish plans for small teams, then read each vendor's own pricing page on October 22, 2026. Where a figure depends on your country (eFax) or is not published (RingCentral), the entry says so. Rankings weigh price for the pages you get, how clearly the plans are laid out, and how plainly the vendor handles HIPAA.
