Search for “best online fax service” and most of what you’ll find is written by fax companies ranking themselves first. Several of the independent reviews that used to rank have been taken down or haven’t been updated in years. So here’s a comparison with list prices from each company’s own pricing page, checked in October 2026, and with the places where each service, including ours, falls short.
Disclosure: we make Browserfax, one of the 14 services below. We’ve tried to make this useful even if you pick a competitor. Where another service is cheaper, has a feature we don’t, or is the better fit, we say so.

The free options, compared
If you just need to send something today, these are the real free allowances. None of them gives you a permanent fax number for free.
| Service | Free allowance | Catch |
|---|---|---|
| Browserfax | 20 pages on Google sign-in | Free pages cover US & Canada destinations |
| Fax.Plus | 10 pages, in total | Send only; phone number verification required |

| Dropbox Fax | 5 pages in total | No receiving, no email-to-fax |
| FaxBurner | 5 sent pages; receive 25 pages/month | The free number expires after 24 hours |
What it actually costs: two common situations
“I fax maybe ten times a year, about 50 pages.” Subscriptions are the wrong tool here. Approximate yearly cost:
| Option | Cost for ~50 pages/year |
|---|---|
| Browserfax | $8: 20 free pages, then two $4 packs (or one $11 pack of 100) |
| Notifyre | $10 minimum top-up (covers far more than 50 pages) |
| Fax.Plus free + pay-as-you-go | ~$10: 10 free pages, then $0.20/page with a $10 minimum top-up |
| FaxZero paid (if faxes exceed 3 pages) | ~$33: ten faxes at $3.29 |
| Cheapest subscriptions | $72–$84/year (Browserfax or Fax.Plus, yearly billing) |
| eFax Personal | $190/year (yearly billing) |
“I need my own fax number and send about 100 pages a month.” Plan pricing with a number:
| Option | Monthly (yearly billing) | Notes |
|---|---|---|
| Notifyre | ~$7.90 | $4.90 number plan + 100 sent pages at $0.03; received pages capped at 200 |
| mFax | $7.99 | Card required at trial; no published monthly page cap |
| Browserfax Basic | $8 ($6) | 100 sent pages; unlimited receiving |
| Fax.Plus Basic | $8.99 ($6.99) | 200 pages |
| Dropbox Fax Home Office | $9.99 ($8.33) | 300 pages |
| MetroFax Essential | $11.95 ($9.96) | 550 pages sent + received |
| eFax Personal | $18.99 ($15.83) | 200 pages sent + received |
The 14 services, one by one
Browserfax: best for occasional senders
Price: 20 free pages (no card), then one-time packs: $4/25, $11/100, $49/1,000 pages, which never expire. Plans with a dedicated US number: Basic $8/month (100 sent pages), Pro $16/month (500 sent pages), both with unlimited receiving. Yearly billing is $72 or $144. Strengths: no subscription needed to send, and nothing to install: it runs at browserfax.com in any browser, with an optional Chrome extension. Live status (Queued → Sending → Delivered), automatic page refunds on failed faxes, no branding on your fax, and incoming faxes delivered to email. Weaknesses: no HIPAA BAA, no native mobile apps (you use the website in a mobile browser), no email-to-fax, no number porting, US numbers only, and sending to 44 countries, where several competitors cover 100+. Uploads are PDF, JPG, and PNG only. Best for: individuals and small businesses who fax a few times a month or less, especially one-off documents like IRS forms, insurance claims, and medical records requests. (One-time fax guide)
Fax.Plus: best low-cost subscription
Price: Basic $8.99/month ($6.99 yearly) for 200 pages and a number, $0.10/page overage. Premium $17.99 adds toll-free numbers and porting. Strengths: genuinely cheap for a full-featured service, with apps for iOS and Android, email-to-fax, a free plan to test, and broad international coverage. Weaknesses: the free plan is 10 pages in total (not per month) and send-only. The BAA is Enterprise-only ($99.99/month). Faxes to high-cost countries can count as 5–10 pages each. Best for: individuals and small offices who want a number, apps, and email-to-fax at the lowest monthly price.
eFax: best-known brand, highest entry price
Price: Personal $18.99/month ($15.83 yearly) for 200 pages, sent and received combined, to the US and Canada, with $0.10/page overage. Business $39.99/month adds 500 pages, 51 countries, and a BAA. Strengths: reliable, with polished iOS, Android, and desktop apps, email-to-fax on every plan, and local or toll-free numbers with porting. Weaknesses: roughly twice the price of comparable plans. Received pages count against your allowance. Annual plans and multi-number accounts must cancel through support rather than online. (eFax vs Browserfax) Best for: buyers who value brand, apps, and support over price, and healthcare teams that need a BAA from an established vendor (Business plan).
RingCentral Fax: best for teams and high volume
Price: Fax 3000 at $27.99/user/month ($22.99 yearly) with 3,000 pages per user. Unlimited internet fax is also included in RingEX Advanced ($25–$35/user/month) and higher. It isn’t included in RingEX Core. Strengths: high page volume, fax numbers in 105+ countries, local/toll-free/vanity numbers, and full apps. It fits naturally if your phones are already on RingCentral. Weaknesses: expensive for one person, overage isn’t published, and cancellation goes through support (by phone or chat). Best for: businesses already using RingCentral, or teams sending thousands of pages.
iFax: feature-rich, confusing pricing
Price: Basic $14.99/month is send-only. A fax number and receiving start with Plus at $29.99/month ($24.99 yearly) for 500 pages. Pro is $39.99. Strengths: apps for iOS, Android, Windows, and Mac; HIPAA features from Plus; team tools and SSO. Weaknesses: iFax’s own pages contradict each other on plan names, page limits, trial length, and which plan includes email-to-fax, so read the pricing page carefully before buying. Best for: teams that want desktop and mobile apps and will verify the plan terms.
Dropbox Fax (formerly HelloFax): best for Dropbox users
Price: Home Office $9.99/month ($99.99/year) for 300 pages, $0.05/page overage. Free tier: 5 pages total, then $0.99 per fax up to 10 pages. Strengths: good value per page, clean web interface, US/UK/Canada numbers, no contract, and it works with Dropbox and Google Drive. Weaknesses: a small free tier, porting only from Professional ($19.99), and no BAA listed on the fax plans. Best for: occasional-to-moderate senders already in the Dropbox ecosystem.
MetroFax: best page volume for the price
Price: Essential $11.95/month ($9.96 yearly) for 550 pages sent and received. Best Value is $14.95 for 1,050 pages. Strengths: the most pages per dollar of any entry-level plan here, with local or toll-free numbers, iOS and Android apps, email fax, and no activation or early-termination fees. Weaknesses: the trial is short (3 days) and requires a card, and its terms prohibit storing protected health information, so it’s not for HIPAA use. Best for: non-healthcare offices with steady volume.
Documo: best for healthcare on a budget
Price: Solo $25/month, billed yearly ($300/year), for 300 pages and $0.15/page overage. Business starts at $80/month yearly. Strengths: a HIPAA BAA on every plan at no extra cost, email-to-fax and fax-to-email, and a 14-day trial with no card. Weaknesses: no monthly billing on Solo. International faxing is off by default and costs extra. An iOS app exists, but we couldn’t find an Android one. Best for: small medical, dental, and therapy practices that need a BAA without an enterprise contract.
mFax (mfax.to): cheap number, card up front
Price: Personal $7.99/month with a US or Canada number, up to 60 pages per fax and 50 faxes a day. Business plans start around $9/month and add email-to-fax and a BAA. Strengths: low price, apps on iOS, Android, Windows, and Mac. Weaknesses: the 7-day trial takes your card at the start, and plans are non-refundable. Not to be confused with Documo, which used to be called mFax. Best for: individuals who want a cheap number with mobile apps.
Notifyre: cheapest per page
Price: sending is pay-as-you-go at $0.03/page with a $10 minimum top-up, and funds don’t expire. Receive plans with a number start at $4.90/month for 200 pages. Strengths: the lowest per-page sending price and the cheapest fax number we found, with a BAA on every plan and free porting. Weaknesses: no free trial. On mobile it’s a web app you add to your home screen, not a store app. Unused received pages don’t roll over. Best for: cost-focused senders with real volume, and small healthcare offices.
Sfax: built for healthcare
Price: Standard $29/month for 350 pages with a toll-free number. The BAA comes with Plus, at $49/month. Strengths: every plan is HIPAA-oriented, and it includes unlimited users and a year of storage. Weaknesses: pricier than Documo or Notifyre for the same BAA coverage. Best for: clinics that want a healthcare-specialist vendor.
FaxZero: best free option for a quick fax
Price: free for 3 pages plus a cover page, up to 5 faxes a day, US and Canada. Paid: $3.29 per fax, up to 25 pages. Strengths: no account at all. You enter details, confirm by email, and send. Weaknesses: the free cover page carries FaxZero branding, there’s no receiving, and per-fax pricing is expensive for repeat use. (FaxZero vs Browserfax) Best for: a single short fax to the US or Canada.
GotFreeFax: cheapest per-fax pricing
Price: free for 3 pages per fax, 2 faxes a day. Paid from $1.25 per fax (up to 10 pages), or 100 prepaid pages for $9.95. Weaknesses: the “free fax number” is a shared, public number, so don’t use it for anything sensitive. Best for: cheap, non-sensitive sending.
FaxBurner: free temporary number
Price: free plan sends 5 pages and receives 25 pages a month on a number that lasts 24 hours. Professional is $14.95/month for a permanent toll-free number and 500 pages. Strengths: email-to-fax even on the free plan, and a temporary number for receiving a one-off fax. Weaknesses: the app is iPhone/iPad only, and there’s no HIPAA option. Best for: receiving a single fax without committing to a plan.
How to choose
- Do you need to receive faxes? If not, skip subscriptions entirely. Use a free tier or page packs.
- How many pages a month? Under ~25: free tiers and packs. 100–300: a $7–$10 plan. 500+: MetroFax, RingCentral, or a pay-per-page service like Notifyre.
- Are you a HIPAA-covered entity? Only consider services that sign a BAA on the plan you’re buying: Documo, Notifyre, Sfax Plus, eFax Business, mFax Business, or Fax.Plus Enterprise.
- Where do you send? Most services price international faxes higher or count them as multiple pages. Check the destination before you buy.
- How do you want to send? Email-to-fax (most subscriptions), native apps (eFax, Fax.Plus, iFax, mFax, MetroFax), or straight from the browser with nothing to install (Browserfax, FaxZero, GotFreeFax).
Fine print worth reading before you pay
- Trials convert. Most paid trials become subscriptions unless cancelled, and several require a card up front (MetroFax, mFax, iFax).
- Sent and received pages often share one allowance (eFax, MetroFax). A busy inbox can push you into overage.
- Annual plans can be hard to cancel. eFax annual plans and RingCentral accounts cancel through support, not a button.
- “Free” usually means “total,” not “per month.” Fax.Plus (10 pages) and Dropbox Fax (5 pages) are one-time allowances.
- International multipliers. A single page to some countries can be billed as 3–10 pages.
