Custom Font in Power BI Embed Not Displaying for End Users

Hi Community,

I'm embedding a Power BI report using Power BI Embedded, and I’ve applied a custom font by modifying the theme with a custom JSON file.

Here’s what I did:

• Added the custom font in the textClasses section of the theme JSON.
• Applied it in Power BI Desktop – works fine on my machine.
• Published and embedded the report via Power BI Embedded.
• However, end users don't see the custom font, and it defaults to something else.

My Goal:
Have the report render the custom font consistently for all viewers when embedded.

What I Tried:

• Verified the theme is applied correctly.
• Font is installed on my local machine.
• Tested in different browsers.
• Ensured users have access to the embed link.

Question:
How can I ensure that custom fonts are rendered correctly for all users in an embedded Power BI report?

Is there a way to bundle the font or load it via a CDN?

Any help or best practices would be appreciated.

Thanks!
