Adding new fonts to GIMP is a simple process that can be completed in a few minutes. First, open the GIMP software and click on the Fonts tab. Then, select the font you want to add from the list and click on the Add button. Once you have added the new font, GIMP will show you a list of options for using it. You can choose to use it as your default font or set it as a specific font for a certain task or project.
