Fax online
Fax without a fax machine with an online fax service
- Send and receive faxes on your PC, via email, or with the RingCentral mobile app

Sending a fax means using a phone line connected to a device such as a printer to send someone a reproduction of printed or scanned documents containing text or images. The combination of phone line and printer is often what’s referred to as a fax machine.
Fax machines use phone lines to transmit electronic data. When you send a document via fax, it’s first scanned as an image and converted into data bits, and then transmitted via phone using your fax machine.
The receiving fax machine converts the bits back into an image and then displays or prints it. Many businesses still use fax, but nowadays send faxes via the internet as opposed to analog phone lines.
Online fax technology means you can send via email or by using fax software on your computer or devices.
Email to fax is one common way you can send a fax from a computer. With this technology, you can attach documents such as Microsoft® Word or PDF files to a regular email, and then send it to a specific fax number.
The recipient can then accept the fax via their fax machine or email inbox. To do this, you’ll need to subscribe to a third-party online fax service to get a fax number.

Throw out your old fax machine and forget about spending another dime on toner or paper. Trim costs on a shoestring budget with modern faxing.
Some people are more comfortable with older technology. This is often the case for decision makers who belong to an older generation, or those who work in remote areas with limited or no access to modern technology. You can easily accommodate such users and communicate more effectively by sending them an online fax.
You’ll still regularly find customers who prefer fax, so to provide the fullest possible service you’ll need a fax option
Fax is also still popular because it provides a paper trail.
You can easily prove a fax was sent from one person to another because you can easily generate a fax log. And, if you need to, there are ways you can do this when you send a fax online.
Government standards suggest that faxing is more secure than email. And some healthcare businesses still follow government advice and use fax instead of undergoing the costly and taxing process of ensuring their email encryption is HIPAA compliant.
It’s easy to fax online from your computer with RingCentral. All you have to do is log on to your account. Then, look for the fax icon in the upper right-hand corner of your dashboard to open the fax window. Fill in the fax number, write your cover page (if you need one), then attach the file you want—up to 20 MB—from your computer or online file storage service. Then, either send your fax right away or at a specified date and time in the future.
On your computer, open your email account, enter the recipient’s fax number and then “@rcfax.com”. On your email subject line, type in the text you want to see on the fax cover page. Then, attach the necessary document and send the email.
Once logged on to your RingCentral account, and armed with the right extension number, click on the FaxOut icon at the bottom of your desktop app. (It’s meant to look like a sheet of paper coming out of a machine.)
Then, enter the recipient’s fax number or select a saved contact and choose a cover page (add a note if you need to). Lastly, drag and drop the file you want to attach or click on the Attach icon (which looks like a paper clip) and choose Send now or Send later.
