PDF Dark Theme

Applies a dark theme to your PDF viewer

⚠️IMPORTANT⚠️: This extension won't work until you give it permission to access file URLs. You can do so by heading to your browser's extension page and enabling file access there.

⚠️IMPORTANT⚠️: This extension will only work on PDFs that you have installed locally on your computer. If you want it to work on PDFs you find online as well i.e. http://www.africau.edu/images/default/sample.pdf, I recommend you use Arshpreet Buttar's DarkPDF extension instead @ https://chrome.google.com/webstore/detail/darkpdf/cfemcmeknmapecneeeaajnbhhgfgkfhp?hl=en.

⚠️IMPORTANT⚠️: Your PDF viewer should be set to light theme for this extension to work. If you try to open up a light PDF document in a dark PDF viewer, this extension is going to invert the colors for both of them. Leaving you with a dark PDF document and a light PDF viewer. You need to have both of a light PDF document and a light PDF viewer for the desired results.

EDIT: As pointed out in the reviews, you can't change the theme for chrome's default PDF viewer without changing the theme of your browser (as of May 2024 at least). I use the Vimium C PDF Viewer chrome extension instead, which gives me a different PDF viewer that can have a theme independent of the browser. Put chrome in dark theme, put vimium C pdf viewer in light theme, and it should work out. You can find that extension here.

This extension is a fork of Buttar's extension (from above) except it's one file only.

let darkPdfDiv = document.createElement('div');
