Go to FaxItOnce.com, upload your PDF, enter the recipient's fax number, and pay $2.75. Your fax transmits immediately. The entire process takes under 2 minutes from any device with a web browser. No account creation, no app download, and no subscription required.

How Much Does a One-Time Fax Cost?

A one-time fax with FaxItOnce costs a flat $2.75 — whether you send 1 page or 45 pages. There is no per-page charge. This flat rate includes transmission, delivery confirmation, and automatic retries if the recipient's line is busy.

FaxItOnce includes up to 45 pages per fax. Retail stores like UPS and FedEx typically charge $1.50-2.00 per page. See full pricing comparison.

What Happens if the Fax Doesn't Go Through?

FaxItOnce automatically retries your fax up to 4 times if the recipient's line is busy or doesn't answer. You receive email confirmation when your fax is delivered. If the fax cannot be completed after all retry attempts, your account is not charged.

What File Formats Can I Fax?

FaxItOnce accepts PDF files. Upload your PDF document directly — there is no file size limit within the 45-page maximum. If your document is in another format, convert it to PDF first using any free online converter.

PDF is the standard format for faxing because it preserves document formatting, fonts, and layout exactly as intended. Most scanners, phones, and computers can create or save documents as PDF. Government agencies, banks, insurance companies, and legal offices all accept PDF files. Need a cover sheet? Use our free fax cover sheet generator to create a professional cover page in seconds.

Can I Send a Fax Internationally?

Whether you are sending a fax to a domestic US number or an international destination, the process is the same: upload your PDF, enter the full fax number with country code, pay $2.75, and your fax transmits immediately. Supported international destinations include Canada, the United Kingdom, Australia, Germany, France, Japan, and dozens of other countries.

How Online Faxing Technology Works

Online faxing — also called internet faxing or web-to-fax — works by converting a digital document into the format that traditional fax machines understand and transmitting it over the telephone network. When you upload a PDF to FaxItOnce, our system converts your document into a fax-compatible image format (TIFF), establishes a connection with the recipient's fax machine, and transmits the document page by page using the T.38 fax relay protocol.

The T.38 protocol is the international standard for sending fax transmissions over IP networks. Unlike older analog fax transmission, T.38 provides error correction and retransmission capabilities, which means your document arrives clearly and completely even over long-distance connections. The entire conversion and transmission process happens in seconds — most faxes are fully delivered within one to two minutes of payment.

Traditional fax machines require a dedicated phone line, paper, toner, and physical maintenance. Online faxing eliminates all of this hardware. With FaxItOnce, any device with a web browser becomes your fax machine. Your document travels from your browser to our secure servers, gets converted, and is delivered to the recipient's fax machine — all without you needing to own, maintain, or even find a physical fax machine.

Why People Still Need to Fax

Despite the prevalence of email and digital communication, faxing remains a requirement in several critical industries. The primary reason is regulatory compliance. In healthcare, the Health Insurance Portability and Accountability Act (HIPAA) recognizes fax as an accepted method for transmitting protected health information (PHI). Hospitals, doctors' offices, pharmacies, and insurance companies routinely require fax for medical records, prescriptions, prior authorizations, and claim forms. The U.S. Department of Health and Human Services provides guidance on HIPAA-compliant transmission methods, including fax, in their HIPAA FAQ.

In the legal industry, faxed documents carry a presumption of delivery that email does not always provide. Courts, attorneys, and notaries frequently require faxed submissions for time-sensitive filings. Financial institutions — banks, mortgage companies, and investment firms — use fax for loan applications, wire transfer authorizations, and account verifications because fax provides a transmission record and a level of authentication that email attachments lack.

Government agencies at the federal, state, and local level also continue to accept and sometimes require fax. The IRS accepts faxed documents for certain tax matters. State DMVs, courts, and permit offices use fax for official document submission. The Federal Communications Commission (FCC) regulates fax communications under the Telephone Consumer Protection Act (TCPA), which governs unsolicited fax advertising — evidence of how embedded fax remains in the regulatory framework. See the FCC TCPA rules for more information.

FaxItOnce vs. Pay-Per-Fax Services

Not all pay-per-fax services are the same. The differences matter most when you look at the actual cost for a real-world fax. The average fax is 11 pages — a length that immediately disqualifies most “free” tier services and reveals the true cost of per-page pricing models.

At 11 pages — the real-world average fax length — FaxItOnce at $2.75 beats FaxZero by $0.54 and includes 10 more pages. Compare all fax services.

“The average fax is 11 pages. At 11 pages, most ‘free’ online fax services cannot complete the fax — Fax.Plus and CocoFax cap free users at 10 pages. FaxItOnce sends up to 45 pages for a flat $2.75 with no account required, making it one of the most cost-effective options for real-world fax lengths.”

The 11-Page Reality: Why Free Fax Services Fall Short

When people search for “free online fax,” they find services like Fax.Plus, CocoFax, and Dropbox Fax that offer free tiers. These services are real, but they come with page limits that make them impractical for most actual fax jobs. The average fax is 11 pages — a stack of medical forms, a loan application, an insurance claim with supporting documents. At 11 pages, the free tier of every major “free fax” service is insufficient.

Fax.Plus offers a lifetime limit of 10 free pages — not 10 pages per fax, but 10 pages total, ever. CocoFax similarly caps free users at 10 pages. Dropbox Fax (formerly HelloFax) limits free users to 5 pages. None of these services can complete the average 11-page fax on their free tier. To send a real-world fax, users must either upgrade to a paid plan (often $7-15 per month) or find a genuine pay-per-fax alternative.

FaxItOnce does not pretend to be free. Instead, it offers a transparent flat $2.75 for up to 45 pages — enough to send the average fax more than three times over. No signup required, no page-count surprises, no subscription trap after the free tier runs out.

Security and Privacy

FaxItOnce takes document security seriously. All communication between your browser and our servers is encrypted using HTTPS (TLS). Your uploaded PDF is processed for fax transmission and then deleted from our servers — we do not retain copies of your documents after the fax is delivered or after all retry attempts are exhausted.

Payment processing is handled entirely by Stripe, which is PCI DSS Level 1 certified — the most rigorous level of certification in the payment card industry. FaxItOnce never sees, stores, or has access to your full credit card number. Your payment information goes directly to Stripe's secure infrastructure.

For users sending sensitive documents — medical records, legal filings, financial information — fax provides a point-to-point transmission that does not pass through third-party email servers or cloud storage platforms. The document travels from our fax gateway directly to the recipient's fax machine over the telephone network. This direct transmission model is one of the reasons healthcare and legal industries continue to rely on fax for document exchange.

Why Are Subscription Fax Services a Bad Deal for One-Time Users?

Subscription fax services like eFax and MyFax charge $15-20 per month regardless of usage. For someone who needs to send just one fax, this means paying $180+ per year for a single transaction. FaxItOnce eliminates this waste with a flat $2.75 fee and no recurring charges.

Most fax services are designed for businesses that send dozens of faxes per month. They charge $10-20 monthly whether you use them or not. But what if you only need to send one fax to your bank? One form to your insurance company? One document to a government office?
