How do I change the background color of a PowerPoint online?

Upload your .pptx file to our tool, pick a solid color from the palette or enter a hex code, and click 'Change Background'. All slides are updated instantly and you can download the result immediately.

Can I use a custom brand color?

Yes! You can enter any hex color code (e.g. #1E3A5F) to match your exact brand colors. The tool also offers 12 preset colors for quick selection.

Can I set an image as the background instead of a color?
