Change Background

Adding a background color to a PDF's pages changes their appearance — from plain white to a color that suits your branding, reading preference, or design context. Choose a color from the picker or enter a hex value. The background is added behind all existing content as a new layer, not replacing the original page. Use cases: adding a brand color background to a certificate or award document, creating a sepia or light-yellow reading background for a long document, preparing a PDF for a branded presentation context, or adding a colored background to a white-background document for visual distinction.
