Quick Verdict: PamFax is a pay-as-you-go fax service with genuine international reach, a free API, and zero monthly minimums — appealing on paper for occasional faxers. In practice, independent testing ranked its fax quality last among major competitors, HIPAA compliance is unconfirmed, there's no email-to-fax, and both plans charge per page on top of the subscription fee. There are better options for most users.
PamFax launched in 2007 as the fax app for Skype, winning the Skype Mashup Competition and carving out a niche as the go-to solution for Skype-era internet faxing. Owned by German company PamConsult Software, it covers 236 countries and has been quietly operating ever since — surviving well beyond Skype's own relevance.
The appeal is real: no credit card required to start, a genuine pay-as-you-go credit model, 100+ supported file formats, and cloud storage integrations. But faxing has matured considerably since 2007, and PamFax's infrastructure and UX haven't always kept pace.
This review covers PamFax pricing, features, fax quality findings, HIPAA status, and who — if anyone — should use it in 2026.

PamFax at a Glance
PamFax is a German-built fax service that pioneered Skype fax integration in 2007. Today it remains a niche choice for occasional international faxers and developers who need a free API — but its quality issues, support gaps, and billing structure make it a hard sell against modern alternatives.

Cons
- Wirecutter testing ranked PamFax last for fax quality among major services
- No email-to-fax — must use the app, web portal, or API
- Paid plans don't include outbound pages — you always pay per page sent
- HIPAA compliance is unconfirmed — no public BAA documentation
- No live chat or phone support — tickets only
- Web portal is dated and awkward to navigate

What Is PamFax?
PamFax is an online fax service developed by Scendix Software GmbH, a subsidiary of PamConsult Software based in North Rhine-Westphalia, Germany. The company also makes Pamela for Skype (a call recorder with over 5 million downloads) and PamBill.
The service lets you send and receive faxes without a physical fax machine across 236 countries. It's available via a web portal, Windows desktop app, iOS and Android apps, and a free developer API. Dedicated local fax numbers are available in the US, UK, Germany, Italy, Australia, and other markets.
PamFax's core differentiator has always been flexibility over value. Rather than selling monthly page bundles, it sells prepaid credit packs — you pay for pages as you need them, or subscribe for a dedicated number without committing to a page quota. For very infrequent faxers, that structure is genuinely appealing.
PamFax Pricing: How It Actually Works
PamFax's pricing model is unlike most competitors, and understanding it upfront will save confusion.
The key thing to know: PamFax's paid plans are number and inbox plans, not page bundle plans. Neither the Basic nor Professional subscription includes any outbound pages. You always purchase sending credits separately.
Pay-As-You-Go Credit Packs
No subscription required. Buy credit as needed:
| Credit Pack | Price (USD ~) | Zone 1 Pages | Per Page |
|---|---|---|---|
| Starter | ~$10.80 | 66 pages | ~$0.16 |
| Medium | ~$32.50 | 200 pages | ~$0.16 |
| Large | ~$54 | 333 pages | ~$0.16 |
| Bulk | ~$108 | 733 pages | ~$0.15 |
Zone 1 covers the US, Canada, and major Western European destinations. International rates vary by country — see the complete guide to international faxing for context on how zone-based pricing works across services.
Larger bulk packs (up to ~8,800 pages) are available only by contacting support@pamfax.biz directly.
Basic Plan (~$7.20/month, billed annually)
- Dedicated local fax number
- Unlimited inbound fax reception
- 3 months of fax storage history
- Outbound sending: ~$0.18/page (purchased separately)
Professional Plan (~$9.75/month, billed annually)
- Dedicated local fax number
- Unlimited inbound fax reception
- Lifetime fax storage
- Company Manager team tool
- Lower outbound rate: ~$0.13/page (purchased separately)
Plans Don't Include Outbound Pages
Unlike most fax services where a $7–10/month plan includes 150–300 pages of sending, PamFax's Basic and Professional plans give you a number and unlimited receiving only. Outbound faxing always costs extra. For a business sending 50 pages/month, add $6.50–$9 on top of the subscription.
All prices are denominated in EUR and converted at current exchange rates — your actual charge in USD will fluctuate slightly. VAT may apply depending on your jurisdiction.
Free Trial
New accounts receive 3 free outbound fax pages — no credit card required. These pages are restricted to Zone 1 destinations (US, Canada, Western Europe). You also get one free month of an inbound fax number to test receiving.
This is a one-time trial allocation, not an ongoing free tier. After the 3 pages are used, you must purchase credits or subscribe to continue. It's useful for a quick test, but not enough to thoroughly evaluate the service.
Key Features
Broad File Format Support
PamFax converts 100+ file formats during transmission: PDF, DOCX, XLSX, PPTX, RTF, PNG, TIFF, JPEG, EPS, DWG, DWF, and many more. Most competitors only accept PDF and common image formats. If you work with CAD files or legacy formats, this is a real differentiator.
Cloud Storage Integrations
Attach fax documents directly from Google Drive, Dropbox, Box, and OneDrive without downloading them first. Received faxes can also be delivered to cloud storage automatically.
Broadcast Faxing
Send a single fax to up to 10,000 recipients simultaneously. This is a significant capability unavailable on most consumer-tier services, and it makes PamFax relevant for bulk communications.
Fax Scheduling
Schedule faxes for future delivery — useful for sending documents during business hours in a different timezone.
Developer API (Free)
PamFax offers a free REST API with a sandbox environment and official SDKs for PHP, Python, Ruby, Java, C#/.NET, and BASH. Developers can build fax functionality directly into applications or create white-label fax products on PamFax's infrastructure. This is a genuine advantage for technical users.
Microsoft Office Integration
The Windows desktop app installs add-ins for Word, Excel, PowerPoint, and Outlook — letting you fax directly from any Office document. This is free and installs automatically.
Notification Channels
Delivery status notifications arrive via email, SMS, Skype, Telegram, or Facebook. The Skype notification channel is PamFax's legacy differentiator — though with Skype's continuing decline in business usage, its practical value is limited in 2026.
Platform Support
| Platform | Available |
|---|---|
| Web portal (portal.pamfax.biz) | Yes |
| Windows desktop app | Yes |
| macOS app | Limited (may be outdated) |
| iOS (iPhone/iPad) | Yes |
| Android | Yes |
| Amazon Appstore | Yes |
| Microsoft Office add-ins | Yes (Windows only) |
| Developer API | Yes (free, with sandbox) |
Fax Quality: The Problem You Need to Know About
This is the most important section of this review.
The New York Times/Wirecutter independently tested major online fax services and ranked PamFax last for fax transmission quality. In their testing, content was barely readable and images failed to come through cleanly — placing PamFax at the bottom of the field.
For a service whose core function is delivering readable documents, this is a fundamental issue. If your use case involves faxing contracts, medical records, tax forms, or any document where legibility matters, this finding alone should disqualify PamFax.
The quality problem likely stems from aging infrastructure — PamFax built its network during the Skype era and hasn't publicly announced major infrastructure upgrades since. Modern services have invested in T.38 protocol optimization and higher-resolution transmission that PamFax appears to lag on. See our troubleshooting guide for blurry faxes for more context on what drives fax quality differences.
Customer Support
PamFax offers:
- Help center at support.pamfax.biz (English and German)
- Support tickets via the web portal
- Email at support@pamfax.biz (required for large credit pack purchases)
- No phone support
- No live chat
Response times are not published. For a paid subscription, having no real-time support channel is a meaningful gap — particularly if a fax fails to deliver before a deadline.
Is PamFax HIPAA Compliant?
Short answer: Unconfirmed.
PamFax uses SSL/TLS encryption for transmission and is GDPR-compliant under German data protection law. Some third-party review aggregators list HIPAA compliance as a feature. However:
- PamFax's official website does not prominently advertise HIPAA compliance
- No Business Associate Agreement (BAA) documentation is publicly available
- No HITRUST certification is documented
- PamFax does not appear on specialist HIPAA fax service lists from healthcare compliance sources
A BAA is the legal cornerstone of HIPAA compliance for a fax service — without a documented, signable BAA, no fax service qualifies as HIPAA-compliant for covered entities. See our guide to HIPAA fax requirements for a full breakdown of what's required.
Healthcare providers should contact PamFax directly before transmitting any PHI. If you cannot get written confirmation of a BAA, use a service with documented HIPAA compliance. mFax Business includes a BAA starting at about $9/mo.
Healthcare Users: Do Not Assume HIPAA Compliance
PamFax does not publicly document a BAA. Using PamFax for protected health information without a signed BAA exposes your organization to HIPAA liability. Always verify BAA availability in writing before transmitting PHI.
PamFax vs. Competitors
| Service | Starting Price | Pages Included | Free Tier | HIPAA | Best For |
|---|---|---|---|---|---|
| PamFax | ~$7.20/mo + per-page | None included (pay-per) | 3 pages (trial) | Unconfirmed | Pay-as-you-go, API users |
| mFax Business | From $9/mo | Build your own (seats + pages) | No | Yes (with BAA) | HIPAA, mobile teams |
| Fax.Plus | $6.99/mo (annual) | 200–4,000/mo | 10 pages (lifetime) | Enterprise only ($80+/mo) | Freelancers, SMB |
| RingCentral Fax | $7.99/mo | 750/mo | No | Yes | Phone + fax bundles |
| eFax | $18.95/mo | 200/mo | No | Yes (eFax Corporate) | Enterprise, US market |
The core difference between PamFax and most competitors: everyone else sells a page bundle. PamFax sells a fax number. That model works if you send fewer than ~15 pages per month — at that volume, pay-as-you-go credits can undercut flat monthly fees. Above that threshold, the math quickly favors competitors.

Who Should Use PamFax?
PamFax makes sense for:
- Very infrequent faxers who send fewer than 15 pages per month and want zero monthly commitment
- International businesses covering obscure country destinations — 236 countries is genuinely broad coverage
- Developers who need a free fax API to integrate into applications; the sandbox, SDKs, and documentation are legitimately good
- Windows + Microsoft Office users who want one-click faxing directly from Office apps
- Broadcast faxers who occasionally need to reach thousands of recipients in bulk
PamFax is not suitable for:
- Healthcare providers or anyone transmitting PHI (no confirmed BAA)
- Businesses sending more than 20–30 pages per month (flat-rate plans are cheaper)
- Anyone prioritizing fax quality — independent testing ranked it last
- Teams needing email-to-fax functionality (not supported)
- Users who need live customer support

Final Verdict
PamFax earns respect for longevity and niche utility. Its pay-as-you-go model is genuinely differentiated, its international coverage is wide, and its developer API is one of the few free options in this category. If you fax a handful of times per year to international destinations and want zero monthly overhead, PamFax is a reasonable tool.
But the fax quality issue is disqualifying for most professional use cases. A fax service that delivers barely-readable transmissions defeats its own purpose. Add the unconfirmed HIPAA status, tickets-only support, and a pricing model that charges per page on top of a monthly subscription, and PamFax becomes difficult to recommend outside its narrow sweet spot.
For mobile faxing with reliable delivery, mFax sends and confirms faxes in under two minutes from any phone — no credit packs, no hidden page math. For business teams that need HIPAA compliance and a dedicated fax number, mFax Business delivers a signed BAA, team accounts, and a web dashboard starting at about $9/mo. Rather than locking you into rigid tiers, it lets you build your own plan with a live calculator — choose the exact seats and pages you need and pay only for what you use.
Send Your Fax Without the Per-Page Math
If PamFax's quality concerns or billing structure give you pause, mFax.to is worth a look. Upload your document, enter the fax number, send — delivery confirmation included. No credit packs. No surprise charges. Over 5 million users trust mFax for exactly this reason.
For business teams needing HIPAA compliance, mFax Business starts at about $9/mo with a BAA, virtual fax numbers, and a shared team dashboard.
