How to Convert PDF to Dark Mode
Read PDFs comfortably at night without straining your eyes
Reading PDFs at night can be exhausting for your eyes. The bright white background creates harsh contrast that leads to eye strain, headaches, and difficulty sleeping. Dark mode solves this problem by inverting colors, making your documents much easier on the eyes.
In this guide, we'll show you how to convert any PDF to dark mode instantly using our free online tool. No software installation, no registration - just upload and download.
The Problem with Regular PDFs
Standard PDFs are designed for printing on white paper, which means they have a bright white background. When you read these on a screen, especially at night:
• The bright light strains your eyes
• It can disrupt your sleep cycle (blue light exposure)
• Long reading sessions become uncomfortable
• OLED screens consume more battery with white backgrounds
Many e-readers and PDF apps offer dark mode, but what about those times when you need to share a dark version, or the app you're using doesn't support it?

- 3Adjust the darkness intensity using the slider
- 4Click "Convert to Dark Mode" and wait a few seconds
