# Export to PDF On-Premises fonts handling

During document writing, the possibility of using many different fonts can be very important to users.

Using the appropriate font can change the appearance of the document and emphasize its style.

PDF Converter allows you to use [Web Fonts](https://pdf-converter.cke-cs.com/v2/convert/docs#section/Web-Fonts), gives you the ability to use standard operating system fonts or use your custom fonts without the need to import them using CSS.

Below is a list of the basic fonts included in the image:

```
OpenSans-Bold.ttf
OpenSans-BoldItalic.ttf
OpenSans-ExtraBold.ttf
OpenSans-ExtraBoldItalic.ttf
OpenSans-Italic.ttf
OpenSans-Light.ttf
OpenSans-LightItalic.ttf
OpenSans-Regular.ttf
OpenSans-Semibold.ttf
OpenSans-SemiboldItalic.ttf
```

However, you can add additional fonts to PDF Converter in two ways:

* Use Unix-like PDF-Converter image `docker.cke-cs.com/pdf-converter` and mount your fonts directory to it. See [Add custom fonts to PDF Converter](#add-custom-fonts-to-pdf-converter) section.
* Use Windows PDF-Converter image `docker.cke-cs.com/pdf-converter-windows` and mount to it fonts directory from the Windows operating system on which the container is running. See [Use Windows fonts in PDF Converter](#use-windows-fonts-in-pdf-converter) section.

> **Note**
>
> The fonts inside the mounted volume will be installed on the docker image operating system. Only the `.ttf` and `.otf` font formats are supported. If you want to use other font formats, you need to convert them to the supported format or use these fonts as [Web fonts](https://pdf-converter.cke-cs.com/v2/convert/docs#section/Web-Fonts).
>
> Make sure that you can install and use converted fonts on your local machine first, before installing them on the docker container.

## Add custom fonts to PDF Converter

If you want to use your custom fonts in your PDF files, you can use the `pdf-converter` Docker image and mount the directory with your custom fonts for the PDF Converter application running on a machine with a Unix-like system (this includes Docker on Windows with a WSL backend).

You just need to run the `docker.cke-cs.com/pdf-converter` Docker image on a Unix-like operating system and mount the `~/your_fonts_dir:/usr/share/fonts/your_fonts_dir` volume.

Launch the Docker container on Unix-like operating system example:

```bash
docker run --init -v ~/your_fonts_dir:/usr/share/fonts/your_fonts_dir -p 8080:8080 -e LICENSE_KEY=[your_license_key] docker.cke-cs.com/pdf-converter:[version]
```

## Use Windows fonts in PDF Converter

If you want to use Windows fonts like Arial, Verdana, etc. in your PDF files, you can use `pdf-converter-windows` Docker image that allows you to run the application on a machine with Windows operating system and mount fonts from the system.

You just need to run `docker.cke-cs.com/pdf-converter-windows` Docker image on Windows operating system and mount `C:\Windows\Fonts:C:\Windows\Fonts` volume.

Launch the Docker container on Windows operating system example:

```bash
docker run -v C:\Windows\Fonts:C:\Windows\Fonts -p 8080:8080 --env LICENSE_KEY=[your_license_key] docker.cke-cs.com/pdf-converter-windows:[version]
```
