Upload your document, enter the recipient's fax number, and hit send. Best Fax transmits it securely and confirms delivery — all from your browser.

Quick Answer

You can send a fax online without a fax machine. Upload a PDF, Word doc, or image to an online fax service, enter the recipient's fax number, and click send. The service converts your file and transmits it over the phone network. Delivery typically takes 1–3 minutes. Best Fax charges $4.95 per fax (no subscription) or $10/month for unlimited faxing.

Any Document Format

Upload PDF, Word, Excel, images (JPG, PNG, TIFF), or use our built-in PDF editor to create documents from scratch. Best Fax converts everything to fax-ready format automatically.

256-Bit Encryption

Your documents are encrypted during transmission with the same security standard used by banks and hospitals. Files are protected from upload to delivery.

If a fax fails due to a busy signal or connection issue, Best Fax automatically retries up to 6 times at no extra cost. Most retries succeed within minutes.

Why Send Faxes Online Instead of Using a Fax Machine?

Physical fax machines are expensive to buy, maintain, and operate. They require dedicated phone lines ($25-40/month), toner, paper, and desk space. They break down, jam, and produce poor-quality output. With Best Fax, you eliminate all of that. Your browser becomes your fax machine — no hardware, no phone line, no maintenance. You can send from anywhere with an internet connection: your office, your home, a hotel room, or a coffee shop. And because everything is digital, you always have a record of what you sent, when, and whether it was delivered.

Online Faxing vs. Traditional Fax: A Quick Comparison

Traditional fax machines require a dedicated phone line, physical presence at the machine, and ongoing supply costs. They print documents in shared spaces where anyone can read them, create no digital audit trail, and cannot send from mobile devices. Online faxing through Best Fax works from any device, encrypts documents during transmission, delivers faxes to private email inboxes, maintains complete delivery records, and costs a fraction of what a traditional fax line costs per month.

Frequently Asked Questions

How long does it take to send a fax online?

Most faxes are transmitted within 1-3 minutes. You'll receive a delivery confirmation as soon as the recipient's fax machine acknowledges receipt. International faxes may take slightly longer due to routing.

Do I need a fax machine to send a fax?

No. Best Fax is entirely browser-based. You just need a computer, phone, or tablet with an internet connection. No fax machine, no phone line, no special software.

What file formats can I fax?

Best Fax supports PDF, Word (DOC, DOCX), Excel (XLS, XLSX), images (JPG, PNG, TIFF), and many other common document formats. PDF typically produces the clearest results.

Can I send faxes internationally?

Best Fax is optimized for US and Canadian fax numbers. International destinations may also work — use the country code followed by the fax number. See our international fax codes directory for formatting examples. Note that not all international destinations have been individually verified.

Is there a limit on how many faxes I can send?

Subscribers on the $10/month plan can send unlimited faxes. The one-time $4.95 option is for a single fax. There are no per-page charges on either plan.

What happens if my fax doesn't go through?

Best Fax automatically retries failed faxes up to 6 times. Common reasons for failure include busy signals (retried automatically), disconnected numbers, or incompatible fax machines. You'll be notified of the outcome either way.
