FaxZero is a free web-based fax service that sends up to 5 faxes per day, 3 pages plus a cover sheet, with FaxZero branding on the cover. Removing the branding and raising the limit to 25 pages costs $3.29 per fax. For a one-off personal fax — a signed form, a rental application — it works and costs nothing. It is not usable for protected health information: FaxZero does not sign a Business Associate Agreement, and HIPAA requires a BAA from any vendor that handles PHI on a covered entity’s behalf. If you are faxing patient records, you need a provider that will sign one. Documo’s HIPAA-compliant cloud fax includes a BAA on every plan from $25/month.
Quick answer: is FaxZero safe to use?
For non-sensitive documents, yes — FaxZero transmits over an encrypted web connection and is a legitimate, long-running service. For anything covered by HIPAA, no. Safety under HIPAA is not only a question of encryption; it is a contractual one. Without a signed BAA, sending PHI through FaxZero is a HIPAA violation on the sender’s part regardless of how well the transmission is protected. The HHS guidance on business associate contracts is explicit that the agreement is required, not optional.
The same reasoning applies to free fax tools generally. “We use encryption” and “we will sign a BAA” are different claims, and only the second one satisfies HIPAA.

What FaxZero actually is
FaxZero is a send-only web fax utility. You fill in a form, upload a PDF or Word file, and it transmits the fax. There is no account, no inbound number, and no app requirement — which is exactly why it’s useful. The free tier allows 5 faxes per day at 3 pages plus a cover sheet that carries FaxZero’s branding. The $3.29 paid option removes the branding and raises the limit to 25 pages.
Its constraints follow from that design. No inbound number means no receiving. No account means no audit trail. No BAA means no PHI. None of these are flaws so much as consequences of being a free one-way tool, and FaxZero is reasonably clear about what it is.
Where FaxZero is the right choice
Genuinely: if you need to send a single non-sensitive fax and don’t want to pay for a subscription, FaxZero is the fastest option available and costs nothing. A subscription cloud fax plan would be the wrong purchase. That is a different purchase from a compliant document platform.
FaxZero stops being the right choice at the point where any of the following becomes true: you need to receive faxes, you need a record of what was sent, you fax more than a few times a month, or the documents contain PHI or other regulated data.
What MyFax is
MyFax is a long-established subscription online fax service, with plans starting at $5/month as of August 2026. Its core workflow is email-based: you send a fax by emailing [faxnumber]@send.myfax.com, and inbound faxes arrive in your email inbox. It includes an inbound fax number, which FaxZero does not.
Where MyFax is limited for regulated industries is compliance documentation. MyFax does not publish a Business Associate Agreement or a HIPAA compliance statement. For a healthcare organization, an absent BAA is disqualifying regardless of the platform’s other merits.
Where MyFax is the right choice
A small business that needs both send and receive, wants an email-based workflow, has no compliance obligations, and is price-sensitive. MyFax is priced below Documo’s entry plan, and if PHI is never involved the missing BAA does not matter.
Is FaxZero HIPAA compliant?
No. FaxZero does not offer a Business Associate Agreement. Under HIPAA, a covered entity may only disclose PHI to a vendor that has signed a BAA committing to safeguard it. No BAA means the vendor cannot lawfully process PHI on your behalf, and the liability for the disclosure sits with you, not with FaxZero.
This is the most common misunderstanding about free fax tools: people assume that because the connection is encrypted, the tool is compliant. Encryption is one of several required safeguards. The contract is a separate, independent requirement. A tool can be technically secure and still make you non-compliant.
Pricing compared, in practice
Per-fax and per-month pricing are hard to compare directly, so here is the same workload costed three ways — 200 pages per month, roughly a small practice’s referral volume:
| FaxZero | MyFax | Documo Solo | |
|---|---|---|---|
| Model | $3.29 per fax, up to 25 pages | Subscription from $5/mo | $25/mo, 300 pages |
| ~200 pages/mo (say 20 faxes) | ~$66/mo | Plan-dependent | $25/mo, within allowance |
| Can receive faxes | No | Yes | Yes |
| BAA | No | No | Yes |
Per-fax pricing looks cheapest at one fax and becomes the most expensive model quickly. At any recurring volume, a subscription wins — and if PHI is involved, only the plans with a BAA are eligible at all.
Where Documo is different
Documo’s entry plan is more expensive than MyFax’s and obviously more expensive than free. The difference it buys is twofold.
First, compliance is not a tier. The BAA, SOC 2 Type II certification, TLS 1.2 in transit, AES-256 at rest, and full audit trails apply on every plan including the $25 Solo plan. Several competitors gate the BAA behind a healthcare-specific or higher-priced tier; the practical consequence is that you can be on the vendor’s platform and still not be covered.
Second — and this is the part a fax comparison usually misses — Documo isn’t just a Cloud Fax platform. Its intelligent document processing layer classifies inbound documents by type, extracts the data fields, and routes the result into a downstream system such as an EHR. A referral arrives as a fax and leaves as structured data in the right patient’s chart, rather than as a PDF in a shared queue for someone to open and retype.
That distinction is why the comparison set for Documo is not really FaxZero and MyFax. Those are transmission tools. If your problem is “we spend hours a day keying in what arrives by fax,” no fax service solves it — that is a document processing problem. Documo’s ROI calculator sizes it against your own volume.
How do I switch from FaxZero or MyFax to Documo?
From FaxZero there is nothing to migrate — no account, no number, no history. Start a free trial, and you’re done.
From MyFax, the only real step is porting your existing fax number so senders don’t have to change anything. Number porting typically takes 2–4 weeks and is carrier-dependent; Documo runs the old and new numbers in parallel during the transition so nothing is dropped. The BAA is executed at signup, not as a later add-on. See contact sales to scope a port.
Is FaxZero safe for sending sensitive documents?
For non-regulated documents, yes — it transmits over an encrypted connection. For PHI, no. FaxZero does not sign a Business Associate Agreement, which HIPAA requires of any vendor handling protected health information on a covered entity’s behalf.
Is FaxZero HIPAA compliant?
No. FaxZero does not offer a BAA. Encryption alone does not make a service HIPAA compliant — the signed agreement is a separate and mandatory requirement.
How much does FaxZero cost?
FaxZero is free for up to 5 faxes per day, 3 pages plus a cover sheet with FaxZero branding. The paid option is $3.29 per fax for up to 25 pages with no branding, as of August 2026.
Can FaxZero receive faxes?
No. FaxZero is send-only and does not provide an inbound fax number. To receive faxes you need a service that assigns you a number, such as MyFax or Documo.
Is MyFax secure enough for HIPAA-regulated faxes?
MyFax does not publish a Business Associate Agreement or HIPAA compliance statement. Without a BAA, it should not be used for PHI.
Does MyFax support sending faxes by email?
Yes. MyFax sends faxes by emailing [faxnumber]@send.myfax.com and delivers inbound faxes to your email inbox.
Is Documo HIPAA compliant?
Yes. Documo includes a Business Associate Agreement on every plan, holds SOC 2 Type II certification, encrypts in transit with TLS 1.2 and at rest with AES-256, and maintains complete audit trails.
What is the best free alternative to FaxZero for healthcare?
There isn’t one, and that’s the honest answer. No free fax tool signs a BAA, because the liability is incompatible with a free service. Any HIPAA-eligible fax platform is paid. Documo’s entry plan is $25/month with a BAA included.
Can I send a fax for free with Documo?
Documo offers a free trial so you can test sending, receiving, and integrations before committing. There is no permanently free tier.
Does Documo have an API?
Yes. The fax API is available on the Business plan and above, for sending, receiving, and status callbacks.
Bottom line
Choose FaxZero for a one-off, non-sensitive fax where paying anything would be absurd.
Choose MyFax if you need send and receive over email, have no compliance obligations, and want the lowest recurring price.
Choose Documo if the documents are regulated, if you need an audit trail, if you fax at any real volume — or if the actual problem is that faxed documents pile up waiting to be read and retyped, which is the problem no fax service solves.
