So keep reading as we share step-by-step guides on how internet faxing works, how to send fax online and share a few benefits and use cases of using online faxing.
How Does Internet Faxing Work?
Internet faxing or online faxing works by sending and receiving faxes over the internet with the help of an online fax service provider. As opposed to traditional faxing, there is no paper or a physical machine involved when faxing over the internet. Instead, attaching files, sending PDFs, or emails is entirely done over the internet via a third-party online fax service provider.
So what happens is that online fax service providers and traditional fax machines use similar technologies for transmitting fax data, only the way you receive or send the fax is different. Online faxing turns your documents into a format that a fax machine can read and vice versa. This means even if the person you are sending the fax to is still using a standard fax machine, you don’t need one. All you need is an internet connection and an online fax setup.
How to Send Fax over the Internet?
Sending faxes over the internet is super easy and convenient. Here’s a step-by-step guide on how to send fax over the internet:

Step 1: Choose an Online Fax Service Provider
Begin by choosing an online fax service provider like Emitrr. If you are a healthcare or legal business owner, ensure that the online fax service you choose offers compliance with HIPAA, GDPR, and more.
Step 2: Create your Account & choose your Fax Number
Once you have chosen an online fax service, the next step is to create an account by entering details like name, email, phone number, your address and payment details. Upon signing up, you will get a dedicated online fax number (toll-free or local number). And if you already have a fax number, then your chosen online fax platform should give you the option to retain it.
Step 3: Prepare your Document
The next step is to prepare the document you would like to send. So create or scan the file you want to fax (PDF, Word, image, etc.) and make sure it’s clear and ready to send.

The sender dials your virtual fax number from their traditional fax machine or online fax service. If they are using a traditional fax machine, then to them, it will look like they are sending a traditional fax.
Step 3: Fax Server Receives the Transmission
Once the sender has sent the fax, the fax will go to the fax service provider and their system will intercept the incoming fax through secure servers. The fax will then be converted into a digital file format (usually PDF or TIFF).
Step 4: You Receive the Online Fax
Finally, you will receive the converted fax into your system, be it mobile app, web portal or email. You can save, read, print or forward this fax instantly via the internet.

- Step 2: In the “To” section, enter the recipient’s fax number followed by your fax service’s domain. For example, 1234567890@emitrr.com
- Step 3: Now add the file you want to send as an attachment. You can also add a subject line, body text or cover letter, if needed, and click on send.
- Step 4: Next, your fax service provider will receive the email, it will convert the attachment into a fax-compatible format (TIFF or PDF). Then the system will dial out to the recipient’s fax number through secure servers to send it across the receiver.
- Step 5: The recipient’s online fax account or traditional fax machine will receive the document as a fax. And to them, it will look like any regular fax transmission.
- Step 6: Finally, you will get the fax delivery confirmation via email.
