FaxChat vs eFax vs Fax.Plus vs HelloFax vs RingCentral Fax: 2026 Head-to-Head

What This Comparison Covers

Five online fax services dominate the English-speaking market in 2026: eFax, Fax.Plus, HelloFax, RingCentral Fax, and FaxChat. This article compares them head-to-head on the variables that actually differentiate them, without padding: pricing, inbox design, number portability, receipts, mobile support, and reliability.

If you want a shorter answer: at 100–500 pages per month, FaxChat Pro is the cheapest per-page option with the only chat-style threaded inbox on the market. If you are an enterprise user needing unlimited pages and an API, eFax or RingCentral Fax is where you end up. Fax.Plus sits in the middle with good pricing but a dated UI. HelloFax is the budget entry point for low-volume senders. The rest of the article explains why.

Head-to-Head Breakdown

Pricing model — subscription vs pay-per-use

Four of the five are subscription-only. FaxChat is the only one of the five with a genuine no-signup pay-per-use option. You can upload a PDF, pay $1.50 + $0.30/page via Stripe Checkout, and send without creating an account or entering any information beyond recipient number and payment details.

Fax.Plus markets "10 free pages" but requires account creation for those, and any subsequent send requires a subscription. eFax, HelloFax, and RingCentral Fax have no pay-per-use model at all.

If you send one fax a year, the subscription-only services cost $120–$240/year for usage that FaxChat handles for $1.80–$5.

Effective cost per page at typical volumes

Monthly bill divided by pages sent, at the volumes where each plan is most commonly used:

FaxChat Pro is the cheapest effective cost per page in the 300–500 range. Below 100 pages, HelloFax is slightly cheaper on base cost. Above 500 pages, Fax.Plus Premium ($29.99 for 500 included pages, $0.06 overage) becomes competitive, and above 1000 pages, direct-to-API services beat all retail providers.

Inbox design — the one thing where they are not all the same

eFax, Fax.Plus, HelloFax, and RingCentral Fax all use a folder-based inbox: one list of received PDFs, one list of sent PDFs. To find the history of faxes with a specific recipient, you filter or search by number.

FaxChat groups faxes into threads by recipient phone number, similar to iMessage or WhatsApp. All back-and-forth with a given contact lives on one page, chronologically. See fax in chat for what this looks like in practice.

Whether this matters depends on your use pattern:

• Faxing the same contacts repeatedly (client matters, agency correspondence, vendor invoices): threading saves significant time over weeks and months.
• Faxing a different number every time (one-off sends, miscellaneous): folder vs threads does not meaningfully affect workflow.

Number portability — who actually owns your number

When you subscribe to a fax service, they assign you a number. The legal question is: is that number "yours" or "theirs"?

• eFax: most restrictive. Documented $500 port-out fee and customer reports of port requests being refused or delayed. If you intend to use the number long-term, this is a lock-in risk.
• RingCentral Fax, Fax.Plus, HelloFax: allow port-out for $25–$100 fees, generally completed in 7–14 business days.
• FaxChat: allows port-out at any time for no fee. Policy position is "the number is yours."

This matters if you put your fax number on a business card, website, letterhead, or legal filing. Changing numbers later is expensive in marketing and administrative terms.

Receipt and delivery-confirmation quality

For business use, delivery evidence matters. Three patterns:

1. Email notification only (HelloFax, Fax.Plus Standard): you get an email saying "your fax was delivered" with a timestamp. Not a proper receipt.
2. In-app delivery log (eFax, RingCentral Fax): more detail than email, but retrieval requires logging in; not a portable receipt you can attach to an expense report.
3. PDF receipt per send (FaxChat): every send generates a Stripe PDF receipt with date, time, recipient, page count, delivery status, and cost. Downloadable, archivable, usable for expense filing and litigation evidence.

If you expense faxes or need audit trail, receipt quality is a real differentiator.

Mobile and browser support

• eFax: app-first. Desktop client, iOS app, Android app. Web interface is limited. If your company blocks installing the desktop app, you will struggle.
• RingCentral Fax: has both app and solid web. Works on mobile browsers.
• Fax.Plus: fully browser-based, good mobile responsive design.
• HelloFax: web-only, no app, reasonably mobile-friendly.
• FaxChat: web-only, fully responsive for mobile browsers. No app required.

If your IT environment restricts desktop software, the web-only providers (Fax.Plus, HelloFax, FaxChat) are safer choices.

Reliability and delivery success

All five services use commercial fax gateways and achieve similar delivery success rates (typically 95–98% on the first attempt, with automatic retry on failure). There is no meaningful reliability differentiator among them for standard use cases.

Edge cases:

• International destinations vary more by provider than domestic.
• Very old recipient fax machines occasionally fail on all services; retry success rates are similar.
• Delivery speed is usually 1–5 minutes across all providers; the claim "fax in seconds" is a marketing simplification.

HIPAA compliance

If you handle Protected Health Information (PHI), you need a signed Business Associate Agreement (BAA), not just a marketing badge. Among these five:

• eFax, Fax.Plus, RingCentral Fax: offer BAAs on specific paid plans. Check the plan details and legal terms, because HIPAA-enabled plans are usually more expensive than standard plans.
• HelloFax, FaxChat: do not offer BAAs. Do not use for PHI.

Who Should Pick Which

Pick FaxChat if:

• You fax the same contacts repeatedly and would benefit from chat-style threading
• You send 100–500 pages per month and want the lowest effective cost
• You value number portability and want to own your number
• You need downloadable PDF receipts for expense filing
• You occasionally have a one-off fax to send and want pay-per-use alongside a subscription option

Pick eFax if:

• You are a large organization that already has eFax and switching would require IT coordination
• You need established API integrations and enterprise features
• You are locked in by corporate procurement

Pick Fax.Plus if:

• You send 300–800 pages/month consistently and the Premium plan's overage rate matters
• You need HIPAA compliance and prefer a smaller vendor than eFax
• You want international faxing with published per-country rates

Pick HelloFax if:

• You send under 100 pages/month and want the cheapest base plan ($9.99)
• You integrate with Dropbox or Google Drive heavily and use their integration
• You do not need number portability or BAA

Pick RingCentral Fax if:

• You are already on RingCentral for phone/meetings and consolidation matters more than fax-specific features
• You have enterprise needs that RingCentral bundles (voice, video, messaging, fax on one bill)

Reversal Case: When to Skip Online Fax Entirely

Some situations where none of these services are the right answer:

• Under 5 pages per year. Use a local copy shop or public library; $1–$3 per send and zero account management.
• Over 1000 pages per month. Go direct-to-API (Telnyx, Phaxio, Documo) for $0.03–$0.05 per page.
• You can e-file or email instead. IRS e-file, secure email, and encrypted upload portals have replaced fax for most use cases. Check if fax is actually required before committing to any service.

Frequently Asked Questions

Which of these services has a free trial? eFax (14 days), HelloFax (30 days), and RingCentral Fax (7 days) have time-limited free trials with credit card required upfront. Fax.Plus gives 10 free pages on signup. FaxChat does not offer a trial; instead, the pay-per-use option ($1.50) lets you send a real fax without committing to a plan.

Is there a winner on reliability? No meaningful difference among these five. All use commercial fax gateways with similar delivery success rates (95–98% first-attempt). Pick on other variables.

Which has the best customer service? Customer service quality varies by region and by issue type. Public review aggregators (G2, Capterra) rank Fax.Plus and FaxChat higher for support responsiveness; eFax has the most public complaints about cancellation friction.

Can I use any of these as a replacement for my landline fax machine? Yes. All five can be configured to receive faxes to a dedicated number that you give to anyone who would otherwise send to a fax machine. FaxChat Pro, Fax.Plus, and RingCentral Fax handle this well out of the box. eFax requires a paid plan for receive.

Do any of these support sending from Gmail or Google Drive directly? HelloFax and Fax.Plus have direct Gmail and Google Drive integrations. FaxChat does not currently integrate with Gmail directly; you download the PDF from Drive and upload it to FaxChat (a 10-second extra step). eFax and RingCentral Fax have email-to-fax features that are not quite the same as a native Drive integration.
