Best One-Time Fax Services Online in 2026
Sometimes you need to send exactly one fax, and paying $10 or more per month for a subscription makes no sense.
This guide compares the best one-time fax online services in 2026, so you can find the cheapest and most reliable option for a single send.

Who actually needs a one-time fax
Most people fax infrequently. A mortgage closing, a medical records request, a court filing. These are one-off events, not ongoing workflows.
Signing up for a monthly fax plan to handle a single document is like renting a warehouse to store one box. The math never works out.
One-time fax services solve this by charging per fax or offering a small credit pack with no recurring billing. You send your document, pay once, and move on.
Common use cases include sending insurance forms, submitting tax documents to the IRS (which still accepts faxed returns and supporting documents), and transferring medical records between providers.
What to look for in a one-time fax service
Not all pay-per-fax services are equal. A few things actually matter when you're choosing one.
- True no-subscription pricing. Some services advertise pay-per-use but quietly require a free account that auto-upgrades. Read the fine print.
- HIPAA readiness. If you're sending anything health-related, the service must support HIPAA compliance. Many budget options skip this entirely.
- Delivery confirmation. You need proof the fax arrived. A timestamp and confirmation page matter, especially for legal documents.
- File format support. PDF is universal, but some services also accept Word documents, images, and spreadsheets without requiring you to convert first.
- International coverage. If you're faxing outside the US, confirm the service covers your destination country.
Security is worth highlighting separately. Fax transmissions can carry sensitive data. AES-256 encryption, both in transit and at rest, is the current standard to look for.
Side-by-side comparison
The table below covers the main one-time or low-commitment fax options available in 2026. Prices are as published at time of writing.
| Service | One-Time Price | Pages Included | HIPAA | No Account Required | International |
|---|---|---|---|---|---|
| Faxend Basic | $2.99 one-time | 5 pages | Yes (all plans) | Yes | 120+ countries |
| FaxBurner (free tier) | Free (1 fax) | 1 page | No | No (account needed) | US/Canada only |
| FAX.PLUS (free tier) | Free | 10 pages lifetime | No (paid plans only) | No | Yes |
| iFax (pay-per-fax) | ~$1.99 per fax | 1 fax | Paid plans only | No | Yes |
| eFax (pay-per-page) | ~$0.10–$0.20/page | Varies | Enterprise only | No | Yes |
| MyFax (trial) | Free trial then $12+/mo | Trial pages | No | No | Yes |
A few caveats. FaxBurner's free tier is genuinely useful for one quick, non-sensitive fax. FAX.PLUS's free lifetime allowance is 10 pages total, which is fine if you never need HIPAA compliance. eFax has strong enterprise integrations but its pay-per-page model adds up fast if you have a multi-page document.

Top picks reviewed
Faxend Basic ($2.99)
Faxend's Basic plan is the most straightforward one-time option in this comparison. You pay $2.99, get 5 outbound pages, and no account is required. The credit is valid for 30 days.
HIPAA compliance is included on every plan, not reserved for a premium tier. That's genuinely unusual in this space. Faxend runs on the T.38 fax-over-IP protocol via the Sinch backbone, covering 120+ countries. Typical delivery for a single page is 30 to 60 seconds.
You can send from the web at faxend.com/send or from the Faxend iPhone app. No subscription, no auto-renewal. If you need more pages later, you upgrade or buy another Basic credit.
The main limitation is that Basic doesn't include a dedicated inbound fax number. If you only need to send, that's irrelevant.
FaxBurner (free tier)
FaxBurner's free option gives you a temporary fax number and one outbound fax. It's genuinely free, which is its biggest advantage. The catch is that it requires an account and is limited to US and Canadian numbers. There's no HIPAA support at the free tier, so it's not suitable for medical documents.
If you need a temporary inbound number alongside your outbound send, FaxBurner is worth considering. See our post on fax apps for iPhone without a subscription for more context on how FaxBurner fits into that category.
FAX.PLUS (free tier)
FAX.PLUS offers 10 free pages as a lifetime allowance. That's enough for a single multi-page document if you haven't used the allowance before. The service has solid international reach, which is a genuine strength. However, HIPAA compliance requires a paid plan, and the free tier doesn't include delivery confirmation in a format suitable for legal purposes.
iFax (pay-per-fax)
iFax positions itself as a team fax tool, and its pay-per-fax pricing reflects that. At roughly $1.99 per fax, it's more expensive than Faxend for a single send. HIPAA is available, but only on higher-tier plans. The interface is polished and it works well on mobile.
eFax
eFax is one of the oldest names in online faxing. Its enterprise integrations, including connections to Salesforce and Microsoft 365, are a genuine advantage for businesses. For a one-time personal fax, though, it's overkill. The pay-per-page model without a subscription requires contacting support in some markets, which adds friction.
A note on HIPAA and sensitive documents
If you're sending protected health information, the rules are specific. The HHS HIPAA Security Rule requires covered entities and their business associates to protect electronic PHI. That includes fax transmissions sent over internet-based services.
A Business Associate Agreement is the key document. It formally establishes that your fax provider is handling PHI under HIPAA obligations. Faxend offers a BAA on request. Most free-tier services do not offer a BAA at all.
If you're a healthcare provider, medical biller, or patient sending your own records, use a HIPAA-ready service. The $2.99 difference between a compliant option and a free one is not worth the risk.
AES-256 encryption, which Faxend uses in transit and at rest, is the encryption standard referenced in NIST guidelines for protecting sensitive data. It's not a marketing phrase. It's a specific technical requirement.
How to send a one-time fax with Faxend
The process takes under two minutes. Here's how it works.
Open faxend.com/send in any browser. No account creation required for the Basic plan.
Type the full fax number including country code. Faxend covers 120+ countries, so international numbers work the same way as domestic ones.
Attach your PDF, Word document, or image file. The Basic plan covers up to 5 pages. Multi-page PDFs are supported without any conversion step.
Complete the payment. No subscription is created. The $2.99 is a single charge and the credit is valid for 30 days.
Hit send. A single-page fax typically arrives in 30 to 60 seconds. You'll receive delivery confirmation so you have a record of the transmission.
If you're on an iPhone, the Faxend iPhone app follows the same steps. You can pull documents directly from Files, Photos, or your email attachments.
Need to receive faxes too? The Standard and Pro plans include an inbound fax number. The guide to receiving faxes online explains how that works in detail.
