Free internet fax services exist — but "free" means very different things depending on the provider. Some give you 5 faxes a day forever. Others hand you 5 pages total and call it a free plan. And a few are just 14-day trials with a credit card trap waiting at the end.
This guide cuts through the marketing. We evaluated 8 free internet fax services on four criteria: how much you actually get for free, whether the free tier is permanent, security practices, and international coverage. If you need to send a fax today without paying a monthly fee, here's exactly what to use.

The 8 Best Free Internet Fax Services
1. Fax.Plus — Best Overall Free Monthly Allowance
Fax.Plus (by Alohi) runs the strongest permanently-free plan in the market: 10 pages per month, every month, with no expiration. No credit card required — just an email address and phone number for verification.
Fax.Plus gives you a real, recurring free allocation — not a one-time credit. Ten pages per month covers most occasional faxers: a 3-page tax form here, a 2-page contract there. The international reach makes it the only free-tier service that works reliably outside North America.
The tradeoff: you can't receive faxes without upgrading. The free plan is send-only, which disqualifies it if you need a fax number for incoming documents. For receive capability, see FaxBurner (#4) or FaxBetter (#5).
Best for: Freelancers, remote workers, and anyone who needs to fax a handful of documents every month without a subscription.
Pros
- 10 pages/month free — resets monthly, permanently
- Covers 180+ countries (unique among free tiers)
- Swiss-based jurisdiction, strong privacy laws
- Clean apps for iOS, Android, and web
- AES-256 encryption even on free tier
Cons
- Send-only — no dedicated receive number on free plan
- Branded cover pages on outgoing faxes
- HIPAA compliance only on Enterprise ($79.99/mo)
- 10 pages disappear fast if you fax multi-page documents
How to get the most from Fax.Plus free
Upload a multi-page PDF rather than sending separate single-page faxes — each transmission counts as one job regardless of page count. Ten pages = roughly three to four multi-page documents per month.
2. FaxZero — Best for Zero Friction (No Account Needed)
FaxZero is the fastest path from document to sent fax. No account. No email verification. No credit card. Open the site, upload your file, enter a fax number, enter your email for the confirmation link, and send. The daily limit resets at midnight Eastern — 5 faxes, up to 3 pages plus a cover sheet each.
FaxZero wins on speed and zero-barrier access. If you need to fax one document right now and don't care about branding on the cover page, nothing is faster. The catch: your recipient sees a FaxZero advertisement on the cover sheet, which looks unprofessional in a business context.
The 3-page limit per fax is the other constraint — many documents (contracts, applications, medical forms) exceed this. For longer documents, GotFreeFax's paid per-fax model or mFax's pay-per-use option are better fits.
Best for: One-time, low-stakes faxes where speed matters more than appearances — sending a form to a utility company, submitting a single-page document to a government office.
Pros
- No registration or account required — fastest to start
- 5 faxes per day, resets daily (most permissive daily limit)
- Operational since 2006 — extremely reliable track record
- Supports PDF, DOC, DOCX, JPG and other common formats
- Pay-per-fax premium option ($3.29) removes branding
Cons
- FaxZero branding ad on every cover page — unprofessional appearance
- US and Canada only on free tier
- No fax receiving capability
- No delivery history or account portal
- Lower image quality — graphics and shading lose detail
- No mobile app
3. GotFreeFax — Best Unbranded Free Faxes
GotFreeFax offers 2 free faxes per day (3 pages each) with one notable advantage over FaxZero: no branding on the outgoing document. Your cover page is clean. The trade-off is a lower daily limit and a slightly less polished interface.
GotFreeFax is the cleaner option when brand presentation matters. Two unbranded faxes per day is enough for most personal use cases: a weekly form, a recurring document submission.
Note: GotFreeFax does offer a free incoming fax feature, but it's secured by only a 4-digit PIN — a significant security gap. Don't use it for sensitive documents. We have a dedicated GotFreeFax review with the full breakdown.
Best for: Occasional users who want clean, unbranded faxes without creating an account.
Pros
- No branding on outgoing faxes — professional appearance
- No account needed for sending
- Mobile-friendly web interface
- Pay-per-fax option for longer documents (from $0.98)
Cons
- Only 2 faxes per day — half of FaxZero's limit
- US and Canada only on free plan
- No fax receiving capability
- Poor security for the receive feature (4-digit PIN only)
- No delivery history without account
4. FaxBurner — Best Free Option for Receiving
FaxBurner flips the model: its free tier focuses on incoming faxes rather than outgoing. You get 25 inbound pages per month and a dedicated fax number — the catch is that the number expires every 24 hours and resets to a new number.
FaxBurner's free plan makes sense in a narrow use case: you need to receive a document or two from someone, you'll give them the number fresh each time, and you don't need to send anything beyond a page or two. The temporary number is a fundamental problem for anything official — you can't put an expiring number on a form, give it to the IRS, or share it with your doctor's office.
The 5 total send pages (not monthly — lifetime) is essentially nothing for ongoing use.
Best for: Receiving a handful of documents from a known sender without a subscription. Avoid if you need a stable fax number.
Pros
- Two-way faxing on free tier — rare among free plans
- 25 pages/month inbound — generous for receive-only use
- Good iOS app with push notifications for incoming faxes
- Reliable delivery confirmation
Cons
- Only 5 pages total to send — ever (not per month)
- Fax number changes every 24 hours — unusable for official correspondence
- iOS only — no Android app
- No HIPAA compliance at any plan level
- Branding on outgoing faxes
5. FaxBetter — Best Dedicated Free Receive Number
FaxBetter takes the receive-only model further: you get a permanent toll-free number (not a 24-hour temporary one) and 50 inbound pages per month, with all faxes delivered as PDFs to your email.
FaxBetter solves a specific problem: you need a stable, permanent fax number to give to healthcare providers, legal offices, or business partners — but you rarely (if ever) need to send faxes yourself. The free tier is genuinely useful for this.
The keep-alive requirement is the catch: if no one sends you a fax within 7 days, your number gets reclaimed. For most users who actively receive faxes, this isn't an issue — but it makes FaxBetter unsuitable if you're just reserving a number for occasional use.
Best for: Individuals who need a stable inbound fax number but don't need to send — real estate agents, healthcare patients, small service businesses that receive occasional paperwork.
Pros
- Dedicated toll-free fax number — permanent (not temporary)
- 50 inbound pages/month free — most generous receive allowance
- All faxes delivered as PDF to email
- Online account portal to view fax history
Cons
- No free sending at all — receive only
- Must receive at least 1 fax from a unique sender every 7 days or lose the number
- No mobile app
- Limited information on encryption/security practices
6. CocoFax — Best Free Trial for Compliance-Sensitive Use
CocoFax isn't a permanently-free plan — it's a 14-day free trial with 10 pages and no credit card required. It earns its spot on this list because it's the only no-payment-required option that offers HIPAA, GDPR, and Canada's PHIPA compliance. That's meaningful if you need to test a compliant fax solution before committing.
CocoFax's trial is uniquely valuable for healthcare, legal, or finance use cases where you need to verify the service handles sensitive documents properly before paying. The triple compliance and AES-256 encryption make it the only no-credit-card option you'd trust with PHI.
If you need a compliant solution long-term, see our full comparison of HIPAA compliant fax services — CocoFax is a solid choice but not the cheapest.
Best for: Healthcare workers, legal professionals, or compliance teams who want to evaluate a secure fax service before subscribing.
Pros
- HIPAA, GDPR, and PHIPA compliant — triple compliance, rare at this tier
- AES-256 encryption + TLS 1.2 — enterprise-grade security
- No credit card required for 14-day trial
- Google Drive, Dropbox, Slack integrations
- Fast delivery (typically under 5 minutes)
Cons
- Not a permanent free plan — expires after 14 days
- Only 10 pages during the trial
- No receiving on the trial/free tier
- Paid plans start at $14.99/month — higher than some competitors
7. Dropbox Fax — Best for Google Workspace and Cloud Users
Formerly HelloFax, Dropbox Fax offers 5 free send pages total — nearly identical to FaxBurner's send limit — but adds built-in e-signature capability and seamless integration with Google Drive, Dropbox, OneDrive, and Box. You can initiate a fax directly from a Google Doc.
Dropbox Fax is worth using exactly once if you're already in the Google or Dropbox ecosystem and want the friction-free sign-then-fax workflow. The 5-page lifetime limit means it's not useful for anything beyond a single test or a genuine one-off document.
For Google-native users who fax more than occasionally, a pay-as-you-go fax service gives better value without a monthly commitment.
Best for: Google Workspace users who need to sign and fax a single document and want the integrated workflow.
Pros
- Built-in e-signature capability — sign and fax in one workflow
- Direct integration with Google Drive, Dropbox, OneDrive, Box
- Send directly from Google Docs without downloading
- Clean, modern interface
Cons
- Only 5 pages total — barely enough for one document
- No mobile app
- No receive capability on free plan
- Requires Dropbox account ecosystem for full benefits
- Paid plans start at ~$9.99/month
8. PC-FAX.com FreeFax — Best Free International Option
PC-FAX.com is the only permanently-free service that covers international destinations. One page per day, global reach. The limit is genuinely low — one page — but if you're outside the US and need to fax abroad without paying anything, it's the only real option.
PC-FAX.com earns its slot only for the international coverage angle. A single page per day is essentially a proof-of-concept rather than a usable service. Practically, Fax.Plus's free tier (10 pages/month, international) is far more useful for international faxing.
Best for: International users who genuinely only need to send a single-page document and can't pay anything.
Pros
- International coverage — works outside North America
- Daily reset — 1 free page per day, every day
- Desktop and mobile apps available
Cons
- 1 page per day is impractical for virtually any real document
- Very limited for multi-page needs
- Less established than competitors
How Free Internet Fax Works
Every internet fax service — free or paid — follows the same technical chain. Understanding it helps explain why truly free tiers are limited.
When you upload a document, the service converts it to TIFF format (the standard fax image format, typically black-and-white at 200 DPI). It then connects to the recipient's fax number via the Public Switched Telephone Network using the T.38 protocol — the ITU standard for transmitting fax signals over IP networks.
That PSTN connection costs real money per minute. Free services offset this cost one of three ways:
- Loss-leader — the free tier exists to convert you into a paying subscriber
- Ad-supported — FaxZero embeds branded cover pages your recipient sees
- Severe limits — 1–5 pages daily limits keep costs below the ad revenue or promotional value
This is why no truly free service offers unlimited pages, HIPAA compliance, or reliable priority delivery. Free queues are deprioritized behind paid customers, which means slower transmission times.
Free fax and sensitive documents don't mix
Free internet fax services do not carry HIPAA Business Associate Agreements (BAA). Sending Protected Health Information (PHI), Social Security numbers, or other sensitive personal data via FaxZero or GotFreeFax is a compliance violation. For sensitive documents, use a service that provides a BAA — or mFax.to's free trial covers your first sends at full security.
Key Limitations to Know Before You Send
Free internet fax services share a set of constraints that most comparison articles understate:
Page caps are strict and often one-time. FaxBurner and Dropbox Fax give you 5 send pages total — not per month. You use them, they're gone. Only FaxZero, GotFreeFax, and Fax.Plus reset on a daily or monthly cycle.
"Receiving faxes free" usually means a temporary or unstable number. FaxBurner's number expires every 24 hours. If you give it to a doctor's office or put it on a form, the number won't work when they call it back.
Image quality is noticeably worse on free services. Documents with graphics, signatures, or shading lose significant detail at the lower quality settings free services use to save bandwidth.
No support. Every service listed here offers zero customer support on the free tier. If your fax fails, you troubleshoot alone.
Delivery is slower. Free faxes are queued behind paid customers. A 2-page fax that takes 45 seconds on a paid plan can take 5–10 minutes on a free tier.
When to Skip Free and Use mFax Instead
Free fax services make sense for one-off, low-stakes documents — a utility form, a library application, a request that doesn't involve sensitive data or a tight deadline.
For everything else, mFax.to is worth the upgrade. The free trial requires no credit card and delivers the full paid experience: 98% delivery success rate, priority transmission, delivery receipts, a real fax number, and the ability to send and receive from your phone in under 2 minutes. Five million users and a 4.8-star App Store rating are the track record that free services can't match.
For teams that need HIPAA compliance, dedicated virtual fax numbers, and multi-user management, mFax Business starts at about $9/mo (billed annually) — and unlike the rigid fixed tiers most providers force on you, it's fully customizable: you build your own plan by setting the exact seats and pages you need with a live calculator and pay only for what you use.

Conclusion
The best free internet fax service depends entirely on what "free" means to you. FaxZero delivers the most daily sends at zero cost — no setup, no account, just upload and send. Fax.Plus gives you the most usable recurring allowance with 10 pages that reset every month. FaxBetter uniquely solves the "I need to receive faxes" problem with a permanent number and 50 inbound pages monthly.
None of them are right for sensitive documents, HIPAA-covered use cases, or anything where delivery reliability is mission-critical. For those situations, try mFax.to — the free trial gives you full-service faxing without a credit card, and it's significantly more reliable than any permanently-free alternative.
