A GPU-Accelerated PDF Dark Mode Converter, That Runs Entirely in Your Browser

This content originally appeared on DEV Community and was authored by BrAtUkA_dotdev

The Problem

• OS dark mode doesn't affect PDF content
• Existing tools upload your files, are slow, or have few options

What I Built

• 16+ themes, GPU-accelerated, fully offline, zero uploads
• Link to live tool + screenshot

How It Works (Technical)

• pdf.js rendering → Canvas API color transform → PDF assembly
• Parallel page processing
• Text layer preservation technique
• Image detection and preservation

Try It / Contribute

• Live link https://bratuka.dev/pdf-dark-mode-converter/
• GitHub link https://github.com/BrAtUkA/pdf-dark-mode-converter
• What I'd love help with (performance, suggestions, etc.)
