This method of faxing through Google's Gmail service works the same on PC and Mac computers because it is web-based.  This means that the file conversion process takes place on an external server, which is a computer that specializes in this task. If you need to send at a later date, you have the option to schedule it.

​Faxing providers support a variety of file formats, enabling you to pick the format that best suits your requirements. Common file formats which are commonly accepted include PDF (Portable Document Format), DOC/DOCX (Microsoft Word), XLS/XLSX (Microsoft Excel), and PPT/PPTX (Microsoft PowerPoint). 

These formats are frequently utilized and guarantee that your documents are easily readable and maintain their layout. Additionally, image formats such as JPEG, PNG, and TIFF are also supported. These formats work especially well when sending scanned documents or files containing graphics and visual elements. ​

​Advantages of Faxing Through Gmail

  • Ease of Use: ​One of the key benefits of faxing from Gmail is its unparalleled ease of use. With just a few clicks, users can create, send, and receive faxes directly from their Gmail accounts. The familiar interface ensures that even non-technical users can quickly grasp the faxing process. This eliminates the steep learning curve that often accompanies the adoption of new technologies.
  • Acquiring a Free Fax Number: ​Gmail's faxing feature gives users the unique benefit of a free fax number. Traditionally, getting a fax number involves additional costs, paperwork, and logistical arrangements. Gmail's solution eliminates these hurdles by providing users with a virtual fax number at no additional cost. This not only saves users money, but also streamlines the process by eliminating the need to wait for a dedicated fax line to be installed.
  • Enhanced Security: ​At a time when data breaches and information leaks are a growing concern, Gmail's fax feature takes security seriously. Integrating faxing into Gmail's existing security infrastructure means that faxes are subject to the same level of protection as email. This includes encryption in transit and at rest, reducing the risk of unauthorized access to sensitive information. In addition, Gmail's multi-factor authentication provides an extra layer of security, ensuring that only authorized personnel can access and send faxes.
  • Elimination of the Need for a Physical Fax Machine: ​Once a staple of the office, fax machines are now bulky relics that take up valuable space and require maintenance. Gmail's faxing feature frees users from the hassle of dealing with physical machines. All they need is an Internet-connected device, be it a computer, tablet, or smartphone. This digital transformation not only saves physical space, but also reduces energy consumption and the need for supplies such as paper and toner. By using Gmail to send faxes, businesses can take a greener and more streamlined approach to communication.

​Is Faxing Over ​Gmail Secure?

​Yes, this way of faxing is even more secure than using a machine to send documents. The first line of defense is encryption.  All services offer advanced encryption methods, which means that your transmission is encrypted into a secret code that can only be interpreted once it reaches the intended recipient.  This makes it extremely difficult for others to intercept and read your faxes.

With a traditional machine, there is a risk that someone could intercept or tamper with your faxed documents while they are in transit or left unattended on the machine. With online faxing, however, the entire process is digital, eliminating these physical vulnerabilities, and you always receive a confirmation email when your fax has been successfully sent. This makes it a safer option for sending important or confidential documents.

Troubleshooting and Common Issues With Gmail Fax

issues. One prevalent problem is the failure of the fax to send. If you encounter this issue, check your internet connection and ensure that you have a sufficient balance or subscription with your chosen fax service provider. Additionally, confirm that the recipient's fax number is entered correctly, as even a small error can lead to delivery failures.

If you receive an error message, such as "fax not sent," consult your fax service provider's support resources or contact their customer service for assistance.

Another issue is the quality of received faxes, which may appear distorted. This can often be resolved by ensuring that your fax documents are of high quality, properly formatted, and saved in a compatible file format like PDF.


1. Does a Fax Provider Only Work with Gmail Accounts?

​You can use any email address you have to send faxes via email.  However, we recommend that you use Google Mail for its security and additional features (such as integration with Google Drive and Google Docs). In any case, whatever email address you use, make sure it is used for faxing only.

2. Do I Need a Fax Number​?

​Yes, the number is your link to the fax servers needed to transmit your files. In addition, you won't be able to receive faxes at all without a number.  Fortunately, almost all services give you a number for free when you create a new account.  You can choose from different types of fax numbers, depending on your country and city. Some services also allow you to use a Google Voice number through porting.

​3. Does My Line Stays On At All Times?

​Yes, your virtual line is always ready to send and receive faxes online. Unlike traditional machines that need to be operated manually, every document that arrives on your virtual number is automatically received in your inbox and a copy is stored in your main provider account.

4. ​Can I Use My Mobile Phone to Send Faxes?

​Yes, the process is the same, you just use the Google Mail application on your mobile device to compose the email message.  Remember, the document must be stored on your phone, and you can take a photo and attach it to the message.  

To make this easier, some services have developed apps that can send, receive, and sign files.

5. Do I Need an Add-On for Gmail Fax?

No, there's no need for ​extensions.  All is done directly from your inbox.
