The Truth About "Free" Faxing

Let's be honest: truly free fax services are rare and all have limitations. Before you get started, here's what you need to know.

Key Takeaway

There's only one 100% free service for sending faxes: FaxZero. But it's limited to sending to the USA and Canada, with an ad on the cover page. For other destinations, or for regular use, a paid plan will be necessary.

That said, several options allow you to send faxes without spending a penny:

  • FaxZero: Truly free, but USA/Canada only
  • Fax.Plus: 10 free pages per month to 180+ countries
  • Free trials: iFax (7 days), MyFax (14 days) - all features

How to Send a Free Fax in 5 Minutes

Here's the fastest method to send a fax for free, step by step.

1

Choose your service

For sending to USA/Canada: FaxZero (no registration). For international: Fax.Plus (account required). For a complete professional service: iFax 7-day trial.

2

Prepare your document

Have your document ready in PDF, Word, or image format (JPG, PNG). Most services accept these formats directly.

3

Fill in the details

Enter the recipient's fax number (in international format: +1 for USA, +44 for UK), your email for confirmation, and attach your document.

4

Send and wait for confirmation

Click Send. You'll receive a confirmation email once the fax is delivered (usually within 1 to 5 minutes).

Limitations of Free Services

Free services have trade-offs. Here's what you need to consider before choosing.

Limited coverage

FaxZero only works to USA/Canada. For Europe or other regions, you'll need Fax.Plus (10 free pages/month) or a paid service.

Restricted volume

3 pages max per fax on FaxZero, 10 pages/month on Fax.Plus. For regular use, a subscription will be necessary.

No receiving

Free services generally only allow sending, not receiving faxes. For that, you need a dedicated number (paid).

No HIPAA

No free service is HIPAA compliant. For sensitive medical documents, a paid service is mandatory.

Frequently Asked Questions About Free Faxing

Is there a 100% free and unlimited fax service?

No. FaxZero comes closest, but it's limited to 5 faxes/day of 3 pages to USA/Canada only. Other "free" services are actually freemium plans with a monthly quota.

Can I send a free fax to the UK or Europe?

Yes, with Fax.Plus which offers 10 free pages per month to over 180 countries, including the UK and Europe. FaxZero does not work to those regions.

Is free fax with advertising professional?

FaxZero adds an ad on the cover page, not on your document. For occasional professional use, it's acceptable. For regular use or important documents, prefer a free trial like iFax.

Can I receive faxes for free?

Rarely. Receiving requires a dedicated fax number, which is typically paid. Fax.Plus includes receiving via email in its free plan but in a limited way.

Does the iFax free trial require a credit card?

No. The 7-day trial does not require a credit card. You can test all features with no commitment.

What's the best option for an urgent fax?

If it's to USA/Canada: FaxZero (immediate, no registration). Otherwise: iFax trial, which allows immediate sending worldwide.
