# Embed a font in a Word document

Font differences across systems can change how a Word document looks. If a target machine doesn’t have the required font installed, layout and styling can shift.

Font embedding solves this by storing font data inside the DOCX file. Recipients then see the document with the intended typography, even when the font isn’t installed locally.

Use this sample when you need consistent rendering for branded templates, technical documents, or shared files across mixed environments.

## Prepare the project

Register the SDK license before you run document operations. For setup details, refer to the [getting started with.NET SDK](https://www.nutrient.io/sdk/dotnet/getting-started.md) guide.

```csharp

using GdPicture14;

LicenseManager licence = new LicenseManager();
licence.RegisterKEY("");

```

## Access font embedding utilities

Font embedding operations live on the static `GdPictureDocumentUtilities` class, so no instance is required:

```csharp

// The GdPictureDocumentUtilities class is now ready for font operations

```

## Define input and output files

Set the source DOCX and output DOCX paths:

```csharp

string inputDocument = @"input_docx_missing_font.docx";
string outputDocument = @"output_docx_embedd_font.docx";

```

## Embed the font in the DOCX

Call `EmbedFontInDocx` with the document paths, font family name, font file path, and embedding options:

```csharp

GdPictureDocumentUtilities.EmbedFontInDocx(inputDocument, outputDocument, @"FreeSans", @"input_font_FreeSansBoldOblique.otf", true, true);

```

Parameters:

- Source document — `input_docx_missing_font.docx`

- Output document — `output_docx_embed_font.docx`

- Font family name — `FreeSans`

- Font file — `input_font_FreeSansBoldOblique.otf`

- Two Boolean flags — Control subset embedding and overwrite behavior

## Handle errors

`EmbedFontInDocx` returns status information you can use in your error handling path. For error handling patterns, refer to the [handling errors with.NET SDK](https://www.nutrient.io/guides/dotnet/best-practices.md#error-handling) guide.

## Conclusion

This workflow embeds a custom font into a Word document so output rendering stays consistent across systems.
