Custom Font in Power BI Embed Not Displaying for End Users

[sandeep07]

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!

Hi @sandeep07 

As far as I'm aware, when using custom fonts, those fonts have to be installed on the local PC. And that is why, if the change is not working for you,

Hi @sandeep07  You can try by hosting the font on a CDN or public URL. Update your theme JSON to reference the font's URL in the externalFonts section. Ensure the server hosting the font supports the correct MIME type and allows CORS.
