FAQ

Is there a truly free fax service?

Yes, there are limited free options. Services like FaxZero and free tiers on apps like Fax.Plus or Dropbox Fax allow users to send a restricted number of pages for free daily or lifetime, though ongoing free services usually include branded cover pages or restrict inbound faxing.

What is the cheapest way to fax something?
