About This Tool
Background Color lets you change the background of your PDF pages to any color you choose. Apply a soft color to the whole document or to selected pages - great for darker reading modes, brand-colored documents, or accessible low-glare versions.
Text and content stay sharp on top of the new background, giving you a fully customized document without editing every element.
The tool runs fully in your browser, so your file stays private and the feature is free.
