Both FaxZero and Browserfax let you send a fax online without a fax machine or phone line — and both have a genuinely free way to do it. The differences show up in the details: how many pages you can send free, what gets printed on your fax, whether you can receive faxes, and what happens when a fax fails.
Here’s the short version, as of July 2026:
- FaxZero is a website for sending the occasional free fax with no signup: up to 5 faxes a day, 3 pages each, US and Canada only, with a FaxZero-branded cover page. Larger faxes cost $3.29 each. It cannot receive faxes.
- Browserfax is a Chrome extension: 20 free pages when you sign in with Google, clean faxes with no ad branding, sending to 50+ countries, live delivery status with automatic refunds on failure — and, on paid plans, your own US fax number with unlimited incoming faxes.

What FaxZero does well
FaxZero has been around for a long time, and its core appeal is real: you can send a fax right now, for free, without creating an account. For a one-off 1–3 page fax to a US or Canada number, that’s about as low-friction as online faxing gets.
A few more genuine strengths:
- Broad file support. FaxZero accepts PDF, Word, Excel, TXT, TIFF, and several other formats. Browserfax focuses on PDF, JPG, and PNG.
- No account, ever. You enter sender and receiver details per fax. There’s nothing to cancel later.
- A quirky civic feature: faxing US members of Congress is free without the usual daily limits.
Where FaxZero’s limits bite
The 3-page free cap is small. Insurance forms, medical records, and IRS paperwork routinely run longer. Go over and you’re in the paid tier — $3.29 per fax (raised from the long-standing $2.09). Browserfax’s free tier is 20 pages, and its paid pages work out cheaper for anything beyond a single fax: a $4 pack covers 25 pages you can spread across as many faxes as you like, and unused pages never expire.
Your free fax carries an ad. The free cover page includes the FaxZero logo and slogan. On a fax to a business, a court, or a government office, that’s not the first impression most people want. FaxZero also prints your name, email address, and IP address in the sender-information area of the fax.
Sending isn’t instant. FaxZero won’t transmit your fax until you click a confirmation link sent to your email — and that email commonly lands in spam, which means the fax quietly never sends. Free faxes are also queued behind paid “priority” faxes, so delivery can lag at busy times. Browserfax sends immediately and shows the real transmission status in the extension as it happens: Queued → Sending → Delivered — and if a fax fails, your pages are refunded automatically.
It’s send-only. FaxZero does not offer fax numbers at all. If a doctor’s office, bank, or agency needs to fax something back to you — which is how most real fax exchanges work — FaxZero has no answer. Browserfax plans ($8/mo Basic, $16/mo Pro) include a dedicated US fax number with unlimited incoming faxes, delivered in Chrome with an email notification and download link for each received fax.
Free means US and Canada. International sending on FaxZero is paid-only, priced per country (roughly $2–$4 per fax, capped at 15 pages). Browserfax’s pages — including the 20 free ones — work to 50+ countries.
Which one should you use?
Use FaxZero if: you need to send one short fax (3 pages or fewer) to a US or Canada number, you don’t mind the branded cover page, and you’d rather not sign in to anything. For that exact job, it’s a fine free tool.
Use Browserfax if: your document is longer than 3 pages, you fax more than once in a while, you’re faxing internationally, you want to see delivery confirmed in real time, or anyone might ever need to fax you back. You get 20 free pages just for signing in with Google — no credit card — and it lives one click away in the browser you already use.
FAQ
Is FaxZero really free?
Yes, within its limits: 5 faxes per day, 3 pages each plus a branded cover page, to US and Canada numbers only. Anything bigger is $3.29 per fax (up to 25 pages).
Can FaxZero receive faxes?
No. FaxZero is send-only and doesn’t assign fax numbers. To receive faxes you need a service that gives you a number — Browserfax includes a dedicated US fax number with unlimited incoming faxes on its plans.
Why is my FaxZero fax stuck?
FaxZero only transmits after you click a confirmation link it emails you. Check your spam folder — if the email is sitting there, the fax is waiting. Free faxes also queue behind paid ones.
Is Browserfax actually free to try?
Yes — sign in with Google and you get 20 free pages, no credit card required. After that, one-time packs (from $4 for 25 pages) never expire, so you’re never forced into a subscription just to send.
