If you use a custom font (other than Word's built-in fonts) in your document, embedding these fonts ensures that whoever views the document sees it the way you want it.
If you've ever opened a Microsoft Word document with a custom font that you didn't embed, you know that Microsoft Word replaces the custom font with your default font setting. This change can disrupt the layout of your document and make it sloppy and difficult to read. You can embed custom fonts in your Microsoft Word document to make sure it keeps your formatting when you send it to someone else. Embedding fonts increases the size of document files, but it is worth it in some situations.
Here's how to embed a custom font in your Microsoft Word document.
In an open document, go to the "File" menu.
In the sidebar that opens, click on the "Options" command.
In the Word Options window, click the "Save" category.
On the right, check the "Embed the fonts in the file" box.
Check the box "Include only the characters used in the document (ideal for reducing file size)". Selecting this option means that Word will only embed a font if it is used in the document. If you do not check this option, Word will embed all of your system's fonts in the file, even if they are not used.
You should leave "Do not embed common system fonts" checked. This option also reduces the file size as it does not integrate common system fonts.
Click "OK" to save your settings.
Now the fonts you used in your document are embedded in the file, and your document will look its best when someone else sees it.
