Issue with PNG Image Transparency and Background Color in Power BI Report Builder PDF Export

[mshao]

Hi Team，

I inserted an image as the cover component for the homepage in Report Builder. The image is in PNG format with a transparent background, and it contains white lines with varying levels of brightness.

After configuring, I published the report to Power BI Service, and the web page display looks fine. However, when I export the report to PDF, all the lines appear with the same color.

The Display on service:

When export to pdf:

I tried converting the image to JPEG format and added a background color matching the report's background. While the background colors appear consistent in Power BI Service, they are different when exported to PDF.

Have you ever met the same issues? Do you have any ideas how can I deal with this issue?

Thanks,

May

Hi @mshao - I think it is due to how Power BI Service and PDF export handle transparency and color rendering.If possible, avoid using elements with semi-transparency in the image. Replace them with solid lines or gradients that visually mimic the transparency.

If you're using Power BI Service to export to PDF, try exporting from Power BI Desktop or SQL Server Report Builder instead.Different tools might handle image rendering more consistently.

If you provide more details about the tools you're using (e.g., Report Builder version, editing tools for the PNG), I can assist further!
