Configuring the Fax Function

The FRITZ!Box can send and receive faxes without any additional devices or software. The fax text is entered and faxes sent in the web browser. Graphic files in JPG or PNG format can be appended to any fax transmission.

The FRITZ!Box can save received faxes and/or forward them to an email address.

Overview

You can use the fax function in different ways: If you would like to send and receive faxes, you need a telephone number only for the fax function. Once the fax function has been configured, you can no longer be reached at this telephone number.

If you would like to remain reachable at all telephone numbers, you can configure the fax function for either sending faxes or receiving faxes. Here is an overview of the options:

Maximum Fax Length

A maximum of ten A4 pages can be transmitted as a fax. If you append a graphics file, page 10 is reserved for the graphics.

Appending Graphic Files

In Google Chrome and Mozilla Firefox you can append graphic files (JPG or PNG format). Images larger than DIN-A4 will be automatically reduced in size.
