How to Fax a Document Online in 5 Steps

You have a document — a signed form, a contract, a medical record, a photo of a paper — and someone on the other end wants it by fax. You don't own a fax machine, and you shouldn't have to. Faxing a document online means a service converts your digital file and transmits it over real fax lines to the recipient's machine. Their end works exactly like receiving any other fax; your end works like attaching a file to an email.

The 5 Steps to Fax a Document Online

1. Get your document into digital form. If it's already a PDF, Word file, or image (JPG/PNG), you're ready. If it's on paper, take a clear, well-lit photo with your phone — that photo works as your document.
2. Upload it. Go to LowFax.com and upload your file in the send form. Multiple pages in one PDF are fine — the page count is detected automatically.
3. Enter the recipient's fax number. Select the destination country and type the number. The country code is filled in for you automatically.
4. Check the price and pay. The exact total is calculated from your page count and destination and shown before you pay. Payment is by card — no account needed.
5. Get your delivery confirmation. Your fax transmits within minutes, and you receive an email confirming delivery — your proof it was sent and received.

What Documents Can You Fax Online?

Anything that can become a file can be faxed. The most common documents people send:

• Signed forms and contracts — sign on paper, photograph it, fax it
• Medical records and insurance forms — many providers still require fax for privacy reasons
• Government and tax documents — the IRS accepts several forms by fax (see our IRS fax guide)
• Legal documents — courts and law offices often accept or require fax submission
• Bank and loan paperwork — authorization forms, verification documents

Tips for a Clean, Readable Fax

• Photographing paper? Lay the page flat, shoot from directly above in good light, and make sure all four corners are in frame. Blurry or angled photos transmit poorly.
• Multiple pages? Combine them into a single PDF if you can — it keeps them in order on the receiving end.
• Double-check the fax number. A fax to a wrong number can't be recalled. Confirm the number with the recipient, especially for sensitive documents.
• Keep your confirmation email. For deadline-sensitive documents, that delivery confirmation is your receipt.

Faxing a Document From Your Phone

Everything above works from a phone browser — no app required. Photograph the document, open the site, upload, and send. We have step-by-step guides for faxing from an iPhone and faxing from Android.
