PDF Background Color

There are many situations where you want to add a background color to PDF pages — making white-background documents easier to read with a light tint, reflecting brand colors in presentations, or color-coding educational materials. Visual consistency and professional appearance are critical in business communications.

This tool lets you upload a PDF, choose a color and opacity, and add a uniform background color to every page in seconds. Six preset colors are available — white, light gray, light yellow, light blue, light green, and light pink — plus full support for custom HEX color codes, giving you unlimited customization options for your brand colors and organizational schemes.

The opacity slider adjusts from 0% to 100%, allowing you to overlay a translucent tint while keeping existing content fully visible and readable. All processing runs locally in the browser using pdf-lib, so your PDF data is never uploaded to any server, ensuring complete privacy and security for confidential documents.

Perfect for improving presentation aesthetics, adding color to print documents, color-coding study materials, categorizing reports by priority or department, and many other professional use cases. Background color addition simplifies document organization, enhances visual hierarchy, and accelerates document management workflows across teams.
