Pay Per Fax Services Compared: What You Actually Pay

Pay per fax services let you send a fax without committing to a monthly subscription, but the real cost per page varies widely once you factor in setup fees, credit expiry, and page limits.

This comparison breaks down what each service actually charges, so you can pick the one that fits how often you fax.

Why pay per fax makes sense

Most people fax fewer than ten pages a month. A $20 monthly subscription for that volume is hard to justify. Pay per fax services charge you only when you actually send something.

The use cases are specific. A patient sending medical records to a new doctor. A freelancer submitting a signed contract. A small business responding to a one-off government form. None of these need a recurring plan.

The problem is that "pay per fax" means different things to different providers. Some charge per page. Others sell page bundles that expire. A few require account creation before you can send a single page. The sticker price rarely tells the full story.

Hidden costs to watch for

Before comparing numbers, its worth knowing the four cost levers that providers use to make their pricing look lower than it is.

Credit expiry. A bundle of 10 pages sounds fine until the credits expire in 14 days and you lose the remainder.
Mandatory account creation. Some services require a paid subscription just to access the pay-per-use option.
Per-minute billing. Older services bill by transmission time, not page count. A slow receiving fax machine can double your cost.
International surcharges. A domestic rate of $0.10 per page can jump to $0.50 or more for international numbers.

Always check the terms for credit expiry windows and international rates before you commit.

Side-by-side comparison

The table below covers the most commonly searched pay per fax options. Prices are based on publicly listed rates at the time of writing.

Service	Entry cost	Pages included	Credit expiry	Account required	HIPAA	International
Faxend Basic	$2.99 one-time	5 pages	30 days	No	All plans	120+ countries
FaxBurner (free tier)	$0	1 page outbound	Temp number expires	Yes	Paid only	Limited
FAX.PLUS (free tier)	$0	10 pages lifetime	One-time, no refill	Yes	Paid only	Yes
eFax Pay Per Use	~$10 setup + per-page fee	Varies	Varies	Yes	Enterprise tier	Yes
MyFax (pay-as-you-go)	$10 minimum deposit	~$0.10/page domestic	12 months	Yes	No	Surcharges apply
Fax.io	$1.99 per fax	Up to 5 pages per fax	Per-transaction	No	No	Extra charge

A few notes on reading this table. FaxBurner's free tier is genuinely useful for receiving a single fax with a temporary number, but outbound is very limited. FAX.PLUS's lifetime free pages are a one-time thing and do not reset. eFax's pay-per-use option is not prominently advertised and often requires contacting sales.

Faxend: no account, no monthly fee

Faxend's Basic plan costs $2.99 and gives you 5 pages with a 30-day validity window. No account creation is required. You go to faxend.com/send, upload your document, enter the recipient's fax number, pay, and send.

That simplicity matters. Many pay-per-fax services bury their one-time option inside a subscription flow. Faxend's entire homepage is built around the no-account use case.

Delivery is fast. A single-page fax typically arrives within 30 to 60 seconds. The service runs on the Sinch backbone, which covers more than 120 countries. So if you need to fax a document to a clinic in Canada or a law office in Germany, the same $2.99 covers it without a separate international rate card.

If you fax more regularly, the Standard plan at $9.99 per month includes 20 pages, full transmission history, and HIPAA compliance. The Pro plan at $19.99 per month adds unlimited pages and a dedicated inbound fax number. You can compare all tiers on the pricing page.

The iPhone app is also worth mentioning. You can photograph a paper document, convert it, and send it without touching a desktop. Download it from the App Store. For a deeper look at mobile faxing, the post on how to send a fax from iPhone covers the full workflow.

Alternatives worth knowing

Honest comparison means acknowledging where other services have real advantages.

FaxBurner is the best option if you need a temporary inbound fax number to receive one document. You get a real fax number for a short window, which Faxend's Basic plan does not offer. If receiving is your primary need, read the post on how to receive a fax online for a fuller breakdown.

FAX.PLUS has strong international reach and a clean interface. Its free tier is genuinely usable for a one-off send, as long as you have not already used the lifetime allocation. It also has team features that make it a reasonable choice for small businesses that share a fax number.

eFax is the dominant enterprise option. If your organization needs deep integrations with Salesforce or Microsoft 365, eFax has years of development behind those connectors. The pay-per-use pricing is not its strength, but the platform is mature.

HIPAA and pay-per-fax

This is an area where pay-per-fax services diverge significantly. Most free tiers and low-cost one-time options do not offer HIPAA compliance. Sending protected health information over a non-HIPAA channel is a violation, regardless of how convenient the service is.

Under the HHS HIPAA Security Rule, covered entities and their business associates must use safeguards for electronic protected health information. That includes fax transmissions sent over internet services.

Faxend includes HIPAA compliance on every plan, including the $2.99 Basic tier. A Business Associate Agreement is available. AES-256 encryption covers data in transit and at rest. That combination is uncommon among pay-per-fax services. Most competitors gate HIPAA behind their most expensive tiers.

If you work in healthcare and need to send even a single document, this distinction matters more than the price difference between services.

Which service to pick

The right answer depends on frequency, direction, and whether HIPAA applies.

If you send fewer than 5 pages and do not need a recurring number, Faxend Basic at $2.99 is the lowest-friction option. No account, no subscription, HIPAA included.

If you need to receive a fax with a temporary number and outbound volume is low, FaxBurner's free tier does that specific job well.

If you send internationally with some regularity, FAX.PLUS has a pricing structure built around that use case and competitive per-page rates for many country codes.

If your organization has enterprise integration requirements, eFax is worth the higher cost. But it is not a pay-per-fax service in any meaningful sense for most users.

For anyone on iPhone who faxes occasionally, the best fax apps for iPhone in 2026 post compares the mobile experience across these services specifically.

One last thing. The cheapest entry price is rarely the cheapest total cost. A $0 free tier that requires an account, expires credits in two weeks, and charges $0.50 per international page can end up costing more than a $2.99 one-time purchase for the same task. Do the math on your actual use case before signing up.

Frequently asked questions

What is the cheapest way to send a single fax online?

Faxend's Basic plan at $2.99 covers 5 pages with no account required, making it one of the lowest-cost options for a single send. FAX.PLUS offers a free lifetime allocation of 10 pages, but you need to create an account and the pages do not reset.

Do pay per fax services support HIPAA compliance?

Most do not, or they restrict HIPAA to their highest-tier plans. Faxend includes HIPAA compliance and AES-256 encryption on every plan, including the $2.99 Basic tier. Always verify HIPAA support before sending protected health information.

Can I send a fax internationally with a pay-per-fax service?

Yes, but international rates vary significantly. Faxend covers 120+ countries at no extra surcharge on the Basic plan. Other services like FAX.PLUS also have strong international coverage, while some older services charge per-minute rates that add up quickly for international calls.

Do I need to create an account to use a pay-per-fax service?

It depends on the service. Faxend's Basic plan requires no account creation. FAX.PLUS, FaxBurner, and eFax all require you to sign up before sending. If you want zero friction, look specifically for services that advertise no-account sending.

How long do prepaid fax credits last before they expire?

Expiry windows vary widely. Faxend's Basic credits are valid for 30 days. MyFax pay-as-you-go credits last 12 months. Some services expire credits in as little as 14 days. Always check the terms before purchasing a bundle.

Is pay per fax better than a monthly subscription?

It depends on volume. If you send fewer than 5 to 10 pages a month, pay per fax is almost always cheaper. If you send regularly or need an inbound fax number, a monthly plan typically offers better value per page.
