What is PDF Dark Mode Converter?

PDF Dark Mode Converter is a free, open-source tool that turns any PDF into a dark-background version you can read comfortably at night or in low light. It runs entirely in your browser. Your files never leave your device.

Why it exists

Most PDFs are designed for print: white pages, black text. That works fine on paper, but on a screen at midnight it is blinding. Operating system dark modes do not touch PDF content. Browser extensions produce inconsistent results. We built this tool so you can convert any PDF to a proper dark color scheme in seconds, with no workarounds or compromises.

How it works

The converter renders each page using your GPU, applies a color transform with 16+ preset themes (Dracula, Nord, Solarized, and more), then assembles a new PDF you can download. The entire process happens locally in your browser using JavaScript. No server, no upload, no waiting.

What makes it different

• Fast. GPU-accelerated color transforms and concurrent page processing. Most documents convert in a few seconds.
• Private. Your PDF never leaves your device. There is no backend, no analytics on your files, no data collection.
• Free and open-source. No sign-up, no trial limits, no watermarks. The source code is on GitHub.
• Flexible. 16+ themes, a custom color picker, adjustable resolution and quality, and both dark and light mode conversions.

Who builds this

PDF Dark Mode Converter is built and maintained by BrAtUkA. It started as a fork and has been rewritten for speed, quality, and usability. Contributions and feedback are welcome on GitHub.
