### Can I use custom fonts in Browser Rendering?

Yes. If your webpage or PDF requires a font that is not pre-installed, you can load custom fonts at render time using `addStyleTag`. This works with both the [REST API](/browser-rendering/rest-api/) and [Workers Bindings](/browser-rendering/workers-bindings/). For instructions and examples, refer to [Use your own custom font](/browser-rendering/reference/supported-fonts/#use-your-own-custom-font).
