Search for a free fax app and you will find dozens of results promising exactly that. Some are genuinely free. Many are free trials that turn into a monthly charge. A few are free for so few pages that they only work for a single short form.

Here is the honest answer: yes, a few free fax services are genuinely free — for short documents, to the US and Canada, a few times a day. Beyond those limits, someone has to pay for the phone line, and it will be you. This guide lists every free option we could verify as of October 2026, with the exact limits, so you can tell in advance whether yours will fit.

We make Faxio, which is not free — it costs $2.99 per fax. We will tell you when a free option is the better choice, because for short documents it often is.

  • Truly free services — no account, no card
  • Free allowances that need a sign-up
  • Free trials — and why they are a different thing

The short answer

Limits below are from each service's own site as of October 2026. Free tiers change often.

Service Free allowance Pages Destinations Account / card The catch
FaxZero 5 free faxes per day 3 + cover US and Canada No account, no card FaxZero branding on the cover page
GotFreeFax 2 free faxes per day 3 per fax US and Canada No account Low daily cap
Fax.Plus 10 pages in total, once 10 total — Account required One-time allowance; no number on the free plan
FaxBurner Send 5 pages total; receive 25 pages/month 5 sent total US and Canada Email sign-up, no card Fax number expires after 24 hours
MyFax 14-day free trial Plan allowance — Account required It is a trial of a monthly plan

If your document is 3 pages or fewer and going to the US or Canada, you can almost certainly fax it free today. If it is longer, international, or you need to fax regularly, no service on this list will do it free indefinitely.

Truly free: no account, no card

FaxZero

FaxZero is the most established free fax site. As of October 2026 it allows up to 5 free faxes a day, each up to 3 pages plus a cover page, to numbers in the US and Canada. It accepts DOC, DOCX and PDF files, needs no account and no credit card, and states explicitly that it is not a free trial.

The catch is the cover page, which carries FaxZero branding. For an informal recipient, that is irrelevant. For a government office, court or medical records department, an advert on the front of your document is a poor look. FaxZero also sells a paid fax at $3.29 for up to 25 pages without branding. See our full Faxio vs FaxZero comparison.

GotFreeFax

GotFreeFax offers 2 free faxes a day, each up to 3 pages, to the US and Canada. Its free cover page has no ads, and it accepts PDF, Word and JPG uploads. The lower daily cap is the main limitation; the clean cover page is a real advantage over FaxZero for formal recipients.

Both sites are web-based rather than apps, which is fine — they work in a phone browser.

Free allowances after sign-up

Fax.Plus

Fax.Plus's free plan comes with 10 free pages to fax in total. That is a one-time allowance, not a monthly one, and the free plan does not include a fax number for receiving. Additional pages on the free plan are charged, and the next step is a paid plan starting at $8.99 a month. For a single fax of a few pages it is genuinely free; it just does not stay free. Full details in Faxio vs Fax.Plus.

FaxBurner

FaxBurner is the best free option for receiving a fax. Its free plan gives you a disposable fax number that lasts 24 hours, lets you receive 25 pages a month, and send 5 pages in total. Sign-up needs an email address but no credit card, and it has an iPhone app. FaxBurner supports faxing within the US and Canada.

The 24-hour number is perfect when a clinic or office is ready to fax you right now. It is not suitable for a number you need to give out and keep. Full details in Faxio vs FaxBurner.

Free trials are not free faxing

Many results for "free fax app" are subscription services offering a trial. MyFax, for example, advertises a 14-day free trial on its Home Office User plan, which is $12 a month afterwards as of October 2026. Other subscription services promote trials too, sometimes with terms that are not spelled out on the pricing page.

A trial can be a fine way to get a fax sent, as long as you treat it as what it is: the start of a subscription. Before you start one, check:

  1. Does it need a card? If yes, billing starts automatically when the trial ends.
  2. When does it end? Put the date in your calendar.
  3. How do you cancel? An online button, or a chat and email process? Our eFax cancellation guide shows what a typical subscription cancellation involves.
  4. What happens to your faxes? Several services delete access to stored faxes when the account closes.

Be wary, too, of checkouts that present a small charge — often around $1 — as a trial or card verification. Our guide to faxing without a subscription explains how to spot that pattern.

Why free fax has limits

Fax still travels over the telephone network. Every page sent costs the provider carrier fees, so a free service has to cover that cost somehow — with advertising on the cover page, a small daily cap, a one-time allowance that introduces a paid plan, or a trial that converts into a subscription.

None of these is a trick. They are just the business model, and knowing which one you are using tells you what the catch will be.

When paying a few dollars makes sense

Free is the right answer more often than fax companies would like to admit. But there are clear cases where it is not:

  • The document is longer than 3 pages and you have used up any sign-up allowance.
  • The recipient is formal — the IRS, a court, an insurer — and a branded cover page looks unprofessional.
  • The destination is outside the US and Canada.
  • It has to arrive the first time, and you want a failed send not to cost you anything.
  • You do not want another account or another trial to remember to cancel.

That is the case Faxio is built for. A single fax is $2.99 for up to 10 pages, with no account and no subscription. If the fax fails, the credit is not consumed, and busy lines are retried automatically. Credits never expire, and bundles bring the price to $2.00 or $1.67 per fax. Faxio delivers to 100+ countries.

Which should you pick

  • 1–3 pages, informal recipient, US or Canada: FaxZero.
  • 1–3 pages, formal recipient, US or Canada: GotFreeFax, for its ad-free cover page.
  • Up to 10 pages once, and you do not mind signing up: Fax.Plus free plan.
  • Someone needs to fax you something today: FaxBurner's free 24-hour number.
  • Longer, international, or must not fail: Faxio for $2.99 — send a fax now.
  • You fax every week: no free option will hold up. Compare paid plans, including Faxio Unlimited at $14.99 a month, in the best fax apps.

On an iPhone or Android phone, all of the web-based options above work in the browser; see how to fax from an iPhone and how to fax from Android for step-by-step instructions.

Frequently asked questions

Is there a truly free fax app?

Yes, within limits. As of October 2026, FaxZero and GotFreeFax send short faxes to the US and Canada for free with no account, and Fax.Plus and FaxBurner offer small free allowances after sign-up. None is free for long documents, international faxes, or regular use.

What is the best free way to send a fax?

For 3 pages or fewer to the US or Canada, FaxZero (up to 5 free faxes a day, with its branding on the cover page) or GotFreeFax (up to 2 free faxes a day, cover page without ads) are the simplest — no account or card needed.

Can I receive a fax for free?

FaxBurner's free plan gives you a disposable fax number that lasts 24 hours and lets you receive up to 25 pages a month, as of October 2026. Permanent numbers require a paid plan with essentially every service.

Are free fax trials really free?

Free trials are free only if you cancel before they end. Several subscription services, including MyFax (14-day trial as of October 2026), offer trials on monthly plans. Note when the trial ends and how to cancel before you start.

Why do free fax services limit pages?

Every fax transmission costs the provider carrier fees, so free tiers cap page counts and daily sends, add advertising, or use the free allowance to introduce a paid plan.
