How it works
A colored background can make a document more readable on screen, visually mark a draft, or match a brand's visual identity. This tool draws a rectangle of the chosen color behind the existing content of each page, without touching the text or images already present.
Does the color hide the existing content?
No, the colored rectangle is drawn first, before the original content: the text and images on the page remain visible on top of the background color.
Can I choose a different color for each page?
No, this tool applies the same uniform color to every page of the document in a single operation.
