No machine? No problem. Here's everything you need to know about sending a fax online in minutes.
Yes — you can fax without owning a fax machine. The simplest option is an online fax service: upload your document from a computer or phone, enter the recipient's fax number, and send it over the internet. You do not need a fax machine, dedicated phone line, or fax software.
If you only need to send a fax once, you also do not necessarily need a monthly fax plan. Pay-as-you-go services can make more sense when you fax occasionally.
💡 Need to send one fax right now? LowFax.com lets you upload a document and send it online starting at $1.99 for up to 10 pages to the US — with no account, subscription, or software installation.
There are several ways to handle faxing without owning a machine. For most people who need to send a document today, an online fax service is the fastest option.
Upload a PDF or image, enter the fax number, and send from your browser. Best for: one-time or occasional faxes.
Some services let you fax from an iPhone or Android app. Best for: sending documents while away from a computer.
Some fax providers convert an email and attachment into a fax. Best for: people who fax regularly from email.
Libraries, shipping stores, office-supply stores, or other local businesses may offer faxing. Best for: when you cannot use an online service.
For a one-time send, the browser-based option is usually the least complicated because you can keep the document digital from start to finish.
Faxing is less common than email, but many organizations still use fax as part of established workflows. The exact requirements depend on the recipient, so always follow the instructions you were given.
Here's exactly how to do it using LowFax.com — it takes less than 5 minutes:
Open your browser on any device — computer, phone, or tablet — and visit LowFax.com. No account or sign-up required.
Click "Upload Document" and select the PDF or image file you want to fax. The system automatically counts your pages and calculates your price.
Type in the fax number you're sending to, select the destination country, and fill in your name and email for the confirmation receipt.
Add a subject line and any notes for the recipient. LowFax automatically generates a professional cover sheet for you — no extra work needed.
Pay securely by credit or debit card. $1.99 for up to 10 pages to the US. Canada starts at $2.99, and international rates are shown when you select your country. Your fax is sent within minutes.
No — not if you already have the document digitally. If the file is a PDF, Word document, or supported image, you can generally upload it directly to an online fax service. Printing and scanning are only necessary when the original document exists on paper and you need to turn it into a digital file first.
Most failed faxes come down to one of a few avoidable issues:
⚠️ Always check for a delivery confirmation email after sending. If a fax fails, a reliable service should notify you and refund the charge automatically rather than leaving you to guess whether it went through.
Most online fax services, including LowFax.com, accept the following file types:
If your document is in another format, simply print it to PDF first — most computers and phones have this built in.
Online faxing can be a practical way to send sensitive documents, but the security of your fax depends on the provider, the recipient, and how you handle the document. Before sending anything sensitive, check the service's security practices and make sure you have the correct recipient number.

Sometimes, but free fax offers often come with page limits, cover-page branding, account requirements, or other restrictions. If you only need to send one document, compare the total cost and the amount of setup involved rather than looking only for the word “free.”
LowFax uses a pay-as-you-go model, so you do not have to keep paying a monthly subscription when you only fax occasionally.
The cost varies by service. Many charge a monthly subscription fee even if you only need to send one fax. LowFax.com works differently — you only pay when you send:
If you only need to send a single fax and never again, see our one-time fax guide. If you fax occasionally and want to understand the pay-as-you-go model in more depth, see pay-as-you-go fax pricing.
Yes. A browser-based fax service can let you send a fax from an iPhone or Android phone without a physical machine. Open Safari or Chrome, upload your document from your phone's files or camera roll, enter the recipient's fax number, and send. See our step-by-step guides for faxing from an iPhone and faxing from Android.
Receiving is different from sending. To receive a fax without a physical machine, you generally need an online fax provider that gives you a fax number and delivers incoming faxes to a web dashboard, app, or email inbox. LowFax is focused on sending faxes, so if someone needs to fax you, confirm that the recipient-side service you choose supports inbound faxing.
LowFax.com currently supports faxing to 12 countries: the United States, Australia, Canada, France, Germany, Hong Kong, Hungary, India, Ireland, Israel, Japan, and the United Kingdom. Just select your destination country on the send form and the rate is shown before you pay. See the international fax guide for more details.
