SVGs are right at home in vector-based design apps. And it's the best way to get Duotone icons into your designs.
You can drop any one of our SVG files into vector-friendly design apps like Figma, Sketch, or Adobe Illustrator, just to name a few. Create a new file or open an existing one, and drag the SVG into the artboard where you would like it placed.

Then use the app's tools for resizing and coloring to get it just right in your design.
Using Kit Custom Icons as SVGs
If you downloaded a Kit with custom icons, the download will include the processed SVG files derived from your original SVGs. You can use these just like you would any of the other Font Awesome icons.
Duotones and SVG
Just like any other style of Font Awesome icons, you can drag and drop a Duotone SVG file into your SVG-friendly application, and the duotone icon will appear. By default, the secondary layer will be set to 40% opacity and the icon will be set to a single color, but you can change that.
Changing Layer Colors and Opacity
To change the color or opacity in a Duotone icon, select and manipulate the opacity and color of individual layers in the SVG you opened. Here are a few examples in action.
