Frequently Asked Questions

Why does Acrobat add a gray border to portfolio images?

Acrobat adds borders by default in certain portfolio themes to visually separate the image cards from the background. This is a stylistic choice tied to the selected portfolio layout template.

Can I change the background color of my PDF portfolio?

Yes, in Acrobat Pro, you can customize the background color or add a background image through the Portfolio layout properties menu to better match your presentation style.

Does flattening the PDF remove the portfolio border?

No, flattening a PDF merges interactive elements on a standard page but does not change the layout properties of a PDF Portfolio, which acts as a container for multiple files. You must edit the portfolio layout settings directly.

Can I remove portfolio borders if I only have Adobe Reader?

No, Adobe Acrobat Reader only allows you to view PDF Portfolios. To edit the layout or visual properties, you need a premium editor like Adobe Acrobat Pro.
