Frequently Asked Questions
What is the cheapest way to send a fax online?
FaxZero is free for up to 5 faxes per day (3 pages each). For occasional paid use, mFax lets you send faxes from your phone with no monthly commitment. For frequent use, FAXAGE starts at $3.49/month — the cheapest subscription available.
Is there a truly free online fax service?
Yes. FaxZero and GotFreeFax both offer free outgoing faxes to US and Canada numbers with no account required. FaxZero allows 5 faxes/day up to 3 pages each; GotFreeFax allows 2 faxes/day. Neither gives you a dedicated fax number for receiving inbound faxes.
Which online fax service has the cheapest monthly plan?
FAXAGE Lite costs $3.49/month — the lowest monthly price of any major online fax service with a dedicated fax number. CocoFax Lite is $4.99/month on annual billing. Both require annual commitments for those advertised prices.
Can I send a fax from my phone without a monthly subscription?
Yes. The mFax app lets you pay per fax with no monthly commitment — you only pay when you actually send. Download from the App Store or Google Play at [mfax.to](https://mfax.to) and fax in under 2 minutes.
What hidden costs should I watch out for with cheap fax services?
Watch for overage fees ($0.10–$0.20 per extra page beyond your monthly limit), annual-only pricing that locks you in, dedicated fax number add-ons ($3–$5/month extra on some plans), and setup fees. The advertised monthly price is rarely the complete cost.
