iFax is a mobile-first fax service built around its iOS and Android apps. It positions itself in the higher-trust corner of the market with HIPAA and GLBA compliance, around-the-clock human support, and a per-page rate of about $1.99 on its pay-per-use plan. The mobile app pairs with a desktop web version and adds scan-and-send features that turn a phone into a document scanner.
For mobile-heavy workflows in regulated industries, that bundle has real value. For occasional senders who do not need an app, the same bundle is more setup than the fax requires, and the per-page rate is at the top end of the pay-as-you-go market. PayPerFax is the most common no-app, no-account iFax alternative. This article compares the two so you can pick the right tool for the fax in front of you.
When iFax is the right choice
iFax is designed around a sender who faxes regularly from a phone and needs compliance features that come with that profile.
iFax makes sense if you:
- Send and receive faxes weekly or more, from a mobile device
- Work in healthcare, finance, or another regulated industry that needs HIPAA or GLBA-aligned handling
- Want an incoming fax number and a managed inbox inside the same app
- Are comfortable installing the iFax app and creating an account
- Want human customer support during business hours and beyond
For that profile, the pricing tradeoff works: you pay roughly $1.99 per page (or step up to a subscription) in exchange for the compliance, support, and mobile workflow.
What iFax actually offers
- Pricing model: Pay-per-page (~$1.99/page) on the PAYG tier, with monthly subscription tiers above it that include incoming numbers and pooled page allowances.
- Apps: Native iOS and Android apps plus a web version.
- Compliance: HIPAA-aligned handling on appropriate plans; GLBA mentioned for financial workflows. Business Associate Agreements available on higher tiers.
- Mobile scanner: Built-in document capture from the phone camera, with edge detection and OCR.
- Receiving: Available on subscription tiers, not on the basic PAYG tier.
- Account required: Yes, on every tier.
- Support: 24/7 human support on higher plans.
Where iFax stops making sense
The features iFax leans on are also where most occasional senders run into friction with it.
The per-page rate is at the top of the PAYG market
At roughly $1.99 per page, iFax charges the same for every page you send. Services with a flat-then-incremental structure (like PayPerFax’s $2 for the first 3 pages, then $0.75 per additional page) come out far cheaper as soon as your fax runs more than a page or two. Most senders are not paying for the compliance certifications on a single fax, but they are paying the premium.
You have to install the app and create an account
iFax is fundamentally an app-and-account product. Even the web version expects a sign-in. For a sender who needs to fax one document and move on, the app install plus account setup is overhead the fax does not need.
Compliance features only matter to some senders
HIPAA and GLBA-aligned handling are real benefits if your job requires them. If your job does not, you are paying for paperwork that does not affect the document you are sending. Most senders sending a personal fax to a doctor’s office do not need a Business Associate Agreement.
The PAYG tier is the basic tier
iFax’s most compelling features (incoming numbers, pooled allowances, full compliance) live on subscription plans. The pay-per-page tier is intentionally light. If you went to iFax expecting the full feature set without a monthly fee, you can end up paying the high per-page rate without getting most of the things that make iFax stand out.
App-only friction on desktop
The mobile experience is the lead product, and that shows on desktop. Senders who only ever fax from a laptop can find the web flow feels secondary to the app.
PayPerFax: the no-app, no-account alternative
PayPerFax is a pay-as-you-go online fax service. You upload a document, enter a fax number, pay $2 for the first 3 pages (then $0.75 for each additional page), and send. There is no app to install, no account to create, and no subscription to manage.
The points that matter most when comparing PayPerFax to iFax:
You only pay when the fax delivers. If the line is busy or the number is wrong, you pay nothing. The charge fires only on successful delivery.
Cheaper for almost every fax above one page. A three-page fax on PayPerFax costs $2 (one flat charge). A three-page fax on iFax costs about $5.97. The savings widen with every additional page.
No app required. The whole flow works from any browser, desktop or mobile. No store install, no permissions to grant, no account to create.
No ads on the fax. PayPerFax does not add anything to the cover page. The document you send is the document the recipient sees.
Live fax tracking. Status updates show on screen as the fax transmits, with an optional browser extension for background tracking.
Mobile-friendly without being mobile-only. The flow works from a phone browser as cleanly as from a desktop. You do not need to commit to one device or one platform.
International coverage to 130 countries. Per-page pricing is shown up front for each destination.
Highest-rated pay-as-you-go fax service. PayPerFax is the top-rated pay-per-use fax service by user reviews.
What PayPerFax does not do is worth saying too:
- No HIPAA Business Associate Agreement. If your workflow requires a signed BAA, you need iFax (or another compliance-focused provider), not PayPerFax.
- No incoming fax number. PayPerFax is for sending only. If you need a number that others can fax to, you need a subscription service.
- No mobile scanner inside an app. PayPerFax accepts documents you upload from your device. There is no in-app camera capture.

Which one should you choose?
The decision splits cleanly.
iFax is the better fit if:
- Your workflow requires HIPAA or GLBA-aligned handling, including a Business Associate Agreement
- You send and receive faxes weekly from a phone and want an integrated inbox
- You want the in-app camera scanner for paper documents
- You are happy installing an app and creating an account
- You are willing to pay the higher per-page rate (or a monthly fee) for those features
PayPerFax is the better fit if:
- You only need to send a fax, not receive one
- Your workflow does not require a signed BAA or other compliance certifications
- You want the cheaper total cost on faxes longer than a single page
- You do not want to install an app or create an account
- You only want to pay when the fax actually delivers
- The destination is international and you want clear per-page pricing before sending
Neither service is strictly better. iFax is the right tool for regulated, mobile-heavy senders. PayPerFax is the right tool for almost everyone else in the pay-as-you-go space.
Other iFax alternatives
If you are shopping the broader market, the other realistic options split into pay-as-you-go and subscription:
- FaxZero offers a free domestic tier (3 pages, US/Canada) with cover-page ads. Right for one-off personal faxes that fit the cap.
- eFax is the largest subscription provider. Plans start around $18.95/month and include an incoming number and HIPAA-aligned handling on appropriate tiers.
- RingCentral Fax bundles fax with a full business phone system. Right for offices, overkill for one-off senders.
- HumbleFax is a smaller subscription with pooled inbound and outbound page allowances.
- MyFax, MetroFax, HelloFax are all subscription services in the $10 to $25/month range.
The pattern: subscription services charge a monthly fee whether you fax or not, but include incoming numbers and (on appropriate tiers) compliance features. If your job needs those features regularly, a subscription saves money. If it does not, pay-as-you-go is cheaper.
Sending a fax without an app install
If you need to send a fax right now and iFax’s app install, account setup, or higher per-page rate are getting in the way, you can do it at payperfax.com without creating an account. Upload the document, enter the fax number, and send. The charge ($2 for the first 3 pages, then $0.75 per additional page) applies only if the fax delivers.
