FaxTo vs FaxZero: free faxing, and what the word "free" is doing
FaxZero is the best free option in this comparison and it is not close: five faxes a day to the US and Canada, up to three pages each, from a browser, with no account. The costs are a FaxZero-branded cover page and a three-page ceiling. If your document is short and the branding does not matter, FaxZero is the correct answer.

Choosing between FaxTo and FaxZero
FaxTo suits you if…
- Your document is longer than three pages.
- You are faxing something official and a third party's branding on the cover page is not acceptable.
- You need to scan a paper document with your phone rather than upload an existing file.
- You need to send outside the US and Canada, or to receive a reply.
FaxZero suits you if…
- Your fax is three pages or fewer, going to a US or Canadian number — send it free, right now, and stop reading.
- You are at a computer with the file already on it.
- You would rather not install anything or create an account.
- You need one fax and will likely never need another.
The free tier is genuinely free
There is no trick worth warning you about. FaxZero sends up to five faxes a day to US and Canadian numbers, three pages each plus a cover page, with no account and no card. For a short letter that is the whole job done at no cost, and any comparison that buries that fact to sell you something else is not being straight with you.
What you give up is on the cover page: free faxes carry FaxZero's branding. For a note to a supplier that is nothing. For a formal filing to a tax office or a court, arriving with an unrelated company's advertisement on the first sheet is a reasonable thing to want to avoid — and FaxZero sells that removal, at $3.29 per fax, along with a 25-page limit and priority delivery.
Three pages goes quickly
A withdrawal letter is one page. A withdrawal letter with the invoice attached is three. Add an ID copy and you are over. Institutional paperwork tends to arrive at four or five pages once the attachments are counted, which is exactly where the free tier stops.
It is a website, not an app
FaxZero runs in a browser, so you need the document as a file already. If what you have is a signed sheet of paper on the table, you need to photograph it, get it onto a machine, and upload it. FaxTo scans with the camera, straightens and enhances the page, merges multiple pages into one PDF and sends — which is the difference between a five-minute task and a twenty-minute one.
