Online Fax Services Compared — And a Free Option That Actually Works

Fax never fully went away. Healthcare, legal, government, and plenty of B2B workflows still require a real fax transmission — not “email a PDF and hope.” Online fax services replace the machine and phone line with a browser, app, or email gateway.

The market is crowded, and many “free” offers are really a handful of trial pages before a subscription. This guide compares well-known providers using official pricing pages and independent reviews, then shows where our free product — EasyFax — fits.

What matters when comparing online fax

Before you lock into a monthly plan, decide what you actually need:

• Send vs receive — Free one-off tools often send only. Receiving usually needs a dedicated fax number and a paid (or genuinely free) inbox.
• Page economics — Compare cost per page, overage rates, and whether image-heavy pages burn extra credits.
• Compliance — HIPAA / BAA is not universal. Some vendors reserve it for enterprise tiers only — verify before you send protected health information.
• Workflow fit — Browser-only is enough for many teams; others need mobile apps, email-to-fax, or cloud storage sync.
• True free vs trial — A replenishing free allowance is different from five signup pages that never refill.

Providers at a glance

Dropbox Fax (formerly HelloFax)

PCMag’s 2026 Best Overall pick for most people. Strong fax quality in their tests, a clean web UI, and unusually flexible pricing — including pay-as-you-go for occasional use.

• Pay-as-you-go — from $0.99 per fax (up to 10 pages), then $0.20 per extra page (per PCMag).
• Subscriptions — from about $9.99/mo for 300 pages send/receive, shareable across multiple senders on base plans.
• Free pages — small signup allotment (PCMag notes five free pages, with extras for optional setup actions).
• Strengths — Quality, Dropbox/Drive/OneDrive/Box forwarding, flexible billing.
• Trade-offs — No dedicated mobile apps; PCMag notes Dropbox Fax does not offer HIPAA compliance on any plan.

Fax.Plus

PCMag’s pick for mobile faxing, with a modern web app and native Android/iOS clients. Competitive subscription pricing for regular senders.

• Free trial pages — 10 free pages on signup (one-time pool on the free tier).
• Basic — from $6.99/mo billed annually for 200 pages/mo (official pricing; monthly list is higher).
• Premium / Business — higher page pools, team seats on Business+.
• HIPAA / BAA — Enterprise tier (official pricing notes HIPAA with BAA on Enterprise only).
• Strengths — Mobile apps, polished UI, ISO 27001 / SOC 2 posture advertised by the vendor.
• Trade-offs — No true pay-as-you-go like Dropbox Fax; team/HIPAA features sit on higher plans.

eFax

The long-running cloud fax brand under Consensus Cloud Solutions — still the name many offices recognize. Oriented toward individuals, teams, and regulated enterprise deployments.

• Personal — entry individual plan with a monthly page pool to the US & Canada (vendor pricing page; promotional intro rates often advertised).
• Business — more pages, multi-user seats, BAA for healthcare workflows.
• Corporate — custom, HITRUST-oriented enterprise stack.
• Strengths — Brand recognition, mature apps, compliance story for larger orgs.
• Trade-offs — Typically pricier than Fax.Plus / Dropbox Fax for light personal use; watch setup fees and overage rules on regional sites.

FaxZero

PCMag’s Best Free Fax Service for simple outbound jobs. No account required for free sends; funded by ads and optional paid priority faxes.

• Free — up to 5 faxes/day, up to 3 pages + cover, US/Canada, with FaxZero branding on the cover.
• Paid one-off — about $3.29 per fax for up to 25 pages, priority vs free queue (per faxzero.com).
• Strengths — Truly free recurring sends; zero signup friction.
• Trade-offs — Send-only (no receive); lower quality than premium services in PCMag tests; cover branding on free tier.

SRFax

PCMag’s pick for HIPAA-focused plans at a relatively accessible price point. Practical when you need a signed BAA without jumping straight to six-figure enterprise fax platforms.

• Healthcare-oriented plans — PCMag cites HIPAA-compliant plans from about $12.60/mo for ~200 pages.
• Strengths — Shared page pools for teams, compliance positioning, straightforward web send/receive.
• Trade-offs — UI feels older than Dropbox Fax / Fax.Plus; no free trial called out in recent PCMag notes.

RingCentral Fax

PCMag’s Best for Businesses when fax sits inside a broader UCaaS stack — high page allowances, apps across platforms, HIPAA support on qualifying plans.

• High-volume plans — PCMag cites examples around $27.99/user/mo for large page pools, with higher tiers bundling voice/video.
• Strengths — Volume, multi-platform apps, unified comms for teams already on RingCentral.
• Trade-offs — Per-user pricing can exceed specialist fax tools if you only need light personal faxing.

EasyFax (Whatever Works) — free browser fax

EasyFax is our own online fax product: secure, browser-based outbound fax, built for people who still need to send documents by fax but do not want another subscription tax on a dusty workflow.

• Price — free to use at easyfax.whateverworks.app.
• Model today — send from the browser; no dedicated fax hardware.
• Receiving — not available yet; inbound fax is on the roadmap and will ship later.
• Workspace — a clean, secure send workspace for individuals and teams — not a 1990s phone closet.
• Strengths — Zero monthly plan to remember; production URL already live; pairs with the rest of the Whatever Works stack when you need hosting, domains, or custom software around the workflow.
• Trade-offs — Send-only for now (no inbound number/inbox yet); not a 30-year enterprise fax brand. If you need to receive today, or need a vendor-signed BAA / FedRAMP paperwork, evaluate specialist vendors (Dropbox Fax, Fax.Plus, SRFax, eFax Corporate, Documo, etc.) against your requirements.

How to choose

1. One-off outbound, no inbox needed — EasyFax (free browser send), FaxZero’s free tier, or Dropbox Fax pay-as-you-go if quality matters more than ads on the cover sheet.
2. Need to receive as well as send — Dropbox Fax or Fax.Plus today; EasyFax inbound is coming later.
3. HIPAA with a signed BAA — SRFax or eFax Business/Corporate (and similar specialists). Do not assume “encryption mentioned in marketing” equals a BAA.
4. Mobile-heavy field work — Fax.Plus (native apps) per PCMag’s testing notes.
5. Already standardized on RingCentral — use their fax SKU before adding a second vendor.
6. Want free browser outbound without a subscription — start with EasyFax.

If your goal is simpler — send a fax from the browser without renting another monthly plan — try EasyFax. It is free, production-ready for outbound today (inbound later), and built by Whatever Works alongside our Self-Host Solutions, Domain & Email Service, and custom software when fax is only one piece of a larger system.
