Change PDF Background Color Online: Eye-Friendly Reading & Custom Styling

Make Your PDF Comfortable to Read

Why Change the Background Color?

• Reduce Eye Strain (Accessibility):
  The Problem: High contrast (black text on white paper) causes "screen glare."
  The Solution: Change the background to a soft Cream or Sepia. This reduces blue light emission and mimics the experience of reading a physical book.
• Night Mode Reading:
  Switching to a dark gray or black background is essential for reading in low-light environments without disturbing others.
• Branding & Aesthetics:
  Add a splash of color to boring administrative documents to match your company’s branding guidelines.
