How we researched this

We compared official pricing and feature pages, app store listings, privacy policies and public user reviews. Prices change, so check the provider's site before you pay.

Key takeaways

  • Fax.Plus is the best overall pick for occasional and small-business faxing, thanks to a real free plan and a low $6.99 per month entry plan.
  • eFax suits larger or healthcare-adjacent teams that need a long track record, but its business plan is needed for a signed business associate agreement.
  • Dropbox Fax suits teams that already use Dropbox Sign, while Documo and SRFax suit healthcare teams that need compliance on every plan.
  • Page counts are not all equal, because some services count slow pages as more than one page, and inbound and outbound pages may have separate quotas.
  • For a truly free fax, use the free tier carefully, check the page limit, and do not send sensitive health or financial documents on a service without clear security terms.

The best online fax services

Online fax services replace a fax machine with email, a web app, or a mobile app, and they give you a fax number without phone hardware. The differences that matter are page allowances, overage fees, security, and whether receiving is included. We compared official pricing pages and recent independent comparisons.

Fax.Plus

Best for: Best overall and free tier

Check out Fax.Plus
Starting price$6.99 per month
Free planYes
Fax.Plus website
fax.plus homepage

Fax.Plus is our pick for most readers because the free plan actually works for occasional faxing. It offers 10 free pages and a Basic plan at $6.99 per month for 200 pages in recent listings, with send and receive included on paid plans. The apps are clean, and signing is built in.

The limit is compliance. If you need a signed business associate agreement for health data, recent comparisons place that on the Enterprise plan, so healthcare teams should check before they rely on the Basic plan. For general business faxing, Fax.Plus is the best value here.

What we like
  • Real free plan with 10 pages
  • Low entry price
  • Wide country coverage
Watch out for
  • HIPAA agreement only on Enterprise in recent listings
  • Higher tiers needed for large volume

eFax

Best for: Established large teams

Check out eFax
Starting price$18.99 per month
Free planNo
eFax app screenshots
App Store screenshots

eFax is the best-known name in online fax, and that history matters for large companies that want a vendor their IT team already knows. The Personal plan is listed at $18.99 per month for 200 pages in recent comparisons, and higher plans add business and corporate features, including healthcare interoperability tools.

Read the terms before you buy. Recent reviews note that a page taking longer than 60 seconds to transmit can count as more than one page, and that the business associate agreement appears from the $39.99 Business plan. If you fax slowly scanned, photo-heavy pages, your allowance may run out faster than expected.

What we like
  • Long track record
  • Large enterprise and healthcare options
  • Phone support
Watch out for
  • Higher entry price
  • Business associate agreement only from the Business plan
  • Page billing rules need reading
03Dropbox Fax logo

Dropbox Fax

Best for: Dropbox Sign users

Check out Dropbox Fax
Starting price$9.99 per month
Free planFree trial
Dropbox Fax website
fax.dropbox.com homepage

Dropbox Fax, formerly HelloFax, is a sensible choice if your documents already live in Dropbox. Sending is simple, files can be archived in Dropbox, and e-signing sits nearby through Dropbox Sign. The Home Office plan is listed at $9.99 per month for 300 pages in recent comparisons.

It is less suited to regulated faxing without a direct check. Recent comparisons note that fax-specific compliance terms are not published as clearly as Documo or SRFax, so ask for written terms before you send health data. For light business faxing, it is easy and dependable.

What we like
  • Simple interface
  • Close link to Dropbox storage and Dropbox Sign
  • Good for occasional sending
Watch out for
  • Pricing is less transparent on the product page
  • Healthcare agreement is sales-gated in recent listings
04Documo logo

Documo

Best for: Healthcare and compliance

Check out Documo
Starting price$25 per month
Free planNo

Documo is the strongest pick for clinics, law offices, and other teams that fax sensitive records. It offers a business associate agreement on all plans in recent listings, with TLS encryption in transit, AES-256 encryption at rest, and an audit trail. The Solo plan is listed at $25 per month when billed annually, for 300 pages.

The price is higher than Fax.Plus or CocoFax, and overage is listed at $0.15 per page on Solo, falling on higher plans. If compliance is a requirement rather than a nice extra, that premium buys clear terms and integrations that cheaper services do not publish.

What we like
  • Business associate agreement on every plan
  • Audit trail
  • EHR integrations
  • E-signature included
Watch out for
  • Higher entry price
  • Overage fees add up
  • Best value for regulated teams, not casual users
05SRFax logo

SRFax

Best for: HIPAA-friendly small teams

Check out SRFax
Starting priceSee website
Free planNo

SRFax is a quiet, dependable option for healthcare and legal teams that need compliance without enterprise pricing. Recent comparisons list HIPAA support on every plan, with a signed agreement available, and the service covers both sending and receiving. It is a good fit for a small clinic that faxes daily but does not need a full phone system.

The downside is polish and price transparency. Check the current SRFax pricing page for your volume, because plans are tiered by pages and features. If you value a clean mobile app above all else, Fax.Plus or iFax may feel more modern.

What we like
  • HIPAA support on every plan in recent listings
  • Simple plans
  • Canadian and US coverage
Watch out for
  • Pricing is not always clear on the main site
  • Interface is plain compared with Fax.Plus
06RingCentral Fax logo

RingCentral Fax

Best for: Teams that need a phone system

Check out RingCentral Fax
Starting price$22.99 per month
Free planFree trial

RingCentral Fax makes sense only if you also need RingCentral for phones, video, or messaging. The Fax 1500 plan is listed at $22.99 per month, or $17.99 per month billed annually, for 1,500 pages in recent comparisons, which is a large allowance. Extra fax lines are available for a small monthly fee.

If you only need fax, that price is hard to justify against Fax.Plus at $6.99 per month. If your team is already moving to RingCentral for voice, adding fax to the same bill and admin panel is a clear win.

What we like
  • Fax bundled with a full business phone system
  • Large page allowance
  • Good for teams that also need voice
Watch out for
  • Expensive if you only need fax
  • 30-day trial, not a free plan
07MyFax logo

MyFax

Best for: Simple low-volume faxing

Check out MyFax
Starting price$10 per month
Free planNo

MyFax is a straightforward service for people who want to send and receive faxes by email with as little setup as possible. Plans start at about $10 per month in recent listings, with 100 pages on the entry tier, and a dedicated number is included. That simplicity suits a small office that faxes a few times a week.

The limits are clear. There is no free plan, and recent comparisons note that MyFax does not offer HIPAA support, so it is not a fit for health records. For general business use, it is easy, but Fax.Plus offers more pages for less money.

What we like
  • Very simple setup
  • Dedicated number included
  • Email-to-fax works well
Watch out for
  • No free plan
  • No HIPAA support in recent listings
  • Higher price per page than Fax.Plus
08iFax logo

iFax

Best for: Mobile-first faxing

Check out iFax
Starting price$8.99 per month
Free planFree trial

iFax is the best pick if most of your faxing starts on a phone. You can scan with the camera, use OCR to make text searchable, sign, and send without a desktop. The entry plan is listed at $8.99 per month in recent comparisons, and Plus and Pro plans include a business associate agreement.

Desktop users may prefer Fax.Plus or Dropbox Fax, which feel more complete on the web. For a field worker, a real estate agent, or a clinician on the move, iFax is a practical mobile-first choice.

What we like
  • Strong mobile scanning and OCR
  • Good for sending from a phone
  • HIPAA agreement on Plus and Pro in recent listings
Watch out for
  • Trial only, not a permanent free plan
  • Page limits vary by plan
09CocoFax logo

CocoFax

Best for: Lowest paid entry price

Check out CocoFax
Starting price$4.99 per month
Free planFree trial

CocoFax is worth a look if price is the main factor and your volume is very low. The entry plan is listed at $4.99 per month for 60 pages in recent comparisons, which undercuts most rivals. Setup is simple, and it covers basic send and receive needs.

The value per page is weaker than Fax.Plus, which offers 200 pages for $6.99 per month, and recent comparisons warn that its HIPAA page is self-attested without a public audit. For a handful of non-sensitive faxes a month, CocoFax is fine. For health data, choose Documo or SRFax instead.

What we like
  • Lowest entry price in this list
  • Simple plans
  • Good for very low volume
Watch out for
  • Only 60 pages on the entry plan in recent listings
  • HIPAA claims are self-attested, not independently audited

How we picked these

We compared official pricing pages and recent independent comparisons that checked vendor pricing pages directly. We favored services that are live today, that state page allowances and overage terms, and that cover different needs, from free occasional faxing to regulated healthcare faxing. We did not claim hands-on testing.

What to check before you buy

Count your real pages for a month, including inbound faxes, because some plans split inbound and outbound quotas. Check overage fees, because a cheap plan with a high overage rate can cost more than a mid-tier plan. Check whether a dedicated number, email-to-fax, and mobile scanning are included or charged extra.

Security for sensitive faxes

For health, legal, or financial documents, ask for a signed business associate agreement in writing if HIPAA applies, and check encryption and retention terms. A vendor page that only says secure is not enough for regulated work. For general business faxing, a known vendor with clear terms is usually enough.

Free fax services and their limits

Truly free faxing exists, but it is limited. Fax.Plus offers 10 free pages, and other services offer trials rather than permanent free plans. Free fax apps that show ads or ask for a card for a trial should be checked carefully, and you should never send a sensitive document through a free service you have not vetted.
