Cheapest Fax Apps for iPhone in 2026

Why fax app costs vary so much

Fax apps charge in very different ways. Some bill per page. Others charge a flat monthly fee regardless of how many faxes you send. A few offer a free tier but watermark your documents or cap you at two or three pages.

The price gap between the cheapest and most expensive options is surprisingly wide. You can pay as little as $2.99 for a one-time send, or as much as $50 a month for an enterprise plan with team inboxes.

Three factors drive the price difference. First, whether you get a dedicated inbound fax number. Second, whether the service is HIPAA-compliant and offers a Business Associate Agreement. Third, how many pages are included before overage charges kick in.

If you fax rarely, a pay-per-use model almost always beats a subscription. If you fax weekly, a low monthly plan makes more sense.

Side-by-side comparison

The table below shows the entry-level cost for each service, what you get, and whether HIPAA compliance is available on that tier.

Prices shown are approximate and subject to change. Always check each provider's current pricing page before subscribing.

Faxend: best for occasional senders

Faxend's pricing is built around a simple idea. Pay only when you actually need to fax something. The Basic plan costs $2.99 as a one-time purchase. You get 5 pages and a 30-day credit window, with no account required.

That makes it the cheapest entry point of any service in this comparison. You are not locked into a monthly cycle.

The Standard plan at $9.99 per month adds 20 pages, a full fax history, and HIPAA compliance. The Pro plan at $19.99 per month gives you unlimited pages and a dedicated inbound fax number. All three plans include AES-256 encryption in transit and at rest.

The Faxend iPhone app lets you send directly from your camera roll, Files app, or any share sheet. Delivery typically takes 30 to 60 seconds for a single page. International faxing is supported across 120+ countries via the Sinch network backbone.

One thing worth noting: HIPAA compliance is available on every plan, not just the top tier. That is unusual. Most competitors reserve HIPAA and Business Associate Agreements for their most expensive tiers. If you work in healthcare and need to send even one fax, the $2.99 Basic plan still qualifies.

eFax: best for enterprise users

eFax is one of the oldest names in online faxing. Its entry plan starts around $16.95 per month, which is significantly more than Faxend or FAX.PLUS. However, it includes 150 combined send and receive pages, a permanent fax number, and integrations with tools like Microsoft 365 and Salesforce.

HIPAA compliance on eFax requires a separate Business plan, which costs more. That makes it harder to recommend for solo healthcare workers who want a cheap option.

Where eFax genuinely excels is enterprise workflow. If your team needs to route faxes to shared inboxes, integrate with document management systems, or handle high monthly volumes, its infrastructure is mature and reliable. For a single user sending occasional faxes, the cost is hard to justify.

FaxBurner: best for one-time temp numbers

FaxBurner offers a free tier with a temporary fax number. You can receive up to 5 pages and send 2 per month at no cost. The number expires after 24 hours unless you upgrade.

That model is genuinely useful for a one-off situation. Need to receive a signed contract just once? FaxBurner handles it without any payment. The trade-off is that the free plan has no HIPAA support and the temporary number cannot be reused.

Paid FaxBurner plans start around $4.99 per month for a permanent number and more pages. That is competitive, but HIPAA compliance still is not available, which rules it out for medical or legal use cases where data privacy matters.

FAX.PLUS: best for international faxing

FAX.PLUS has a free tier that gives you 10 pages per month. Its paid plans start at around $6.99 per month. The service supports a wide range of countries and has a clean iPhone interface.

For international reach, FAX.PLUS is a strong option. It covers destinations that some smaller services do not. The T.38 fax-over-IP protocol it uses helps maintain reliability across long-distance connections.

HIPAA compliance on FAX.PLUS is limited to the Business plan, which is priced higher. For domestic US faxing with HIPAA on a budget, it is not the most cost-efficient choice. But if you regularly fax internationally and do not need HIPAA, it competes well on price.

How to pick the right plan

Start by counting how many faxes you send per month. If the answer is fewer than five, a pay-per-use service almost always costs less than any subscription.

Next, decide whether you need to receive faxes. Most cheap plans do not include an inbound number. If you only need to send, you can skip that feature entirely and save money.

HIPAA matters if you work in healthcare, insurance, or any field covered by the HIPAA Privacy Rule. Check whether the plan you choose includes a Business Associate Agreement, not just marketing language about being "HIPAA-friendly." Faxend provides a BAA on all plans.

If you want to send faxes directly from your iPhone without a desktop, look for apps with a native iOS app rather than a mobile web wrapper. The experience is noticeably better. Our post on how to send a fax from an iPhone walks through the process step by step.

Finally, watch for overage fees. Some services advertise a low base price but charge $0.10 or more per page once you exceed the included count. A plan that looks cheap can get expensive fast if you send a 40-page document.

Frequently asked questions

What is the cheapest way to send a fax from an iPhone?

Not always. Many low-cost services reserve HIPAA compliance for higher-priced tiers. Faxend is an exception and includes HIPAA compliance and a Business Associate Agreement on all plans, including the $2.99 Basic tier.

Do free fax apps actually work on iPhone?

Some do, with limits. FaxBurner and FAX.PLUS both offer free tiers, but they cap you at a small number of pages per month. Free tiers also typically lack HIPAA compliance and permanent fax numbers.

Can I send a fax from my iPhone without a subscription?

Yes. Faxend's Basic plan is a one-time purchase with no recurring billing. You pay $2.99, get 5 pages, and the credit is valid for 30 days. After that, you only pay again when you need to send another fax.
