What These Scores Mean
The security ratings represent pass/fail assessments for malware and phishing (Google, Norton, Trend Micro), while reputation scores reflect user experiences and business practices. FaxZERO’s 96% combined score confirms it’s a legitimate, secure service in the top tier of online fax providers we’ve evaluated.
Company Reputation
FaxZERO maintains consistently high ratings across review platforms. User complaints typically focus on delivery issues rather than security concerns — a common pattern in the fax industry due to the inherent limitations of fax technology rather than provider-specific problems.
The service has improved its customer support responsiveness based on user reviews across the evaluated platforms, with faster resolution times for delivery issues reported in recent feedback compared to older reviews.

Privacy Policy Highlights
FaxZERO’s privacy policy includes:

Known Limitations
Some users report partially transmitted faxes, particularly with large documents or poor recipient line quality. This reflects general fax technology limitations rather than service-specific issues.
FaxZero’s Drawbacks
FaxZERO is a secure, legitimate service — but security isn’t the only thing that matters when you’re trying to send a fax. Independent reviewers have flagged several usability issues worth knowing about.
Outdated interface
FaxZERO’s interface hasn’t kept up with modern web design. As TechRadar puts it:
"FaxZero’s interface feels like it’s from the late ’90s." — TechRadar
This doesn’t affect security, but it does affect the experience.
Two-step sending process
Free faxes don’t send instantly. Tom’s Guide explains:
"Your FaxZero fax will not send instantly: You must first wait for an email with a link to your fax, and then click on the link to deliver it." — Tom’s Guide
This anti-spam measure adds a delay that can be frustrating when you need a fax out quickly.
Ads on free faxes
FaxZERO places ads on the cover page of free faxes. Understandable for a free service, but a problem if you’re faxing something professional — a legal document, a business form, a medical record.
No mobile support
There’s no mobile app or mobile-optimized interface. PCMag notes:
"FaxZero lacks a mobile app, which is a significant disadvantage in an increasingly mobile world." — PC Mag
Limited image quality
Faxes with images or graphics lose detail. As Crazy Egg observed:
"FaxZero is a better option for sending documents that are mostly text-based. If you’re sending images, you can expect most of the details to be lost and blurred." — Crazy Egg
Premium pricing
While basic domestic faxes are free (up to 3 pages plus cover, 5 per day, US/Canada only), premium and international faxing runs around $3.63 for up to 15 pages. PC Mag notes the pricing is "high" compared to alternatives for non-free use.
How PayPerFax Compares
If FaxZero’s limitations matter for your use case, here’s how PayPerFax stacks up as an alternative:
| FaxZero | PayPerFax | |
|---|---|---|
| Price (domestic) | Free (with ads + limits) or ~$2.09 | Pay-per-fax, no subscription |
| Price (international) | ~$3.63 | Competitive per-page rates |
| Mobile support | None | Mobile-optimized |
| Ads on faxes | Yes (free tier) | No |
| Failed fax charges | Charged | No charge for failed faxes |
| Trustpilot rating | 3.3/5 | 4.7/5 |
| Account required | No | No |
PayPerFax is not free — you pay per fax sent. The trade-off is no ads, no email verification delay, mobile support, and no charges when a fax fails to deliver. It’s the top-rated pay-as-you-go fax service for a reason.
Bottom Line
FaxZERO is safe and legitimate. The security scores confirm that. It’s a solid choice for occasional domestic faxing when you don’t mind the ads, the two-step process, or the dated interface.
If you need something more polished — mobile access, no ads, reliable international delivery, or higher image quality — a pay-per-use service like PayPerFax addresses those gaps without locking you into a subscription.
