Description from store
⚠️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.
```js
let darkPdfDivStyles = `
pointer-events: none;
width: 100vw;
height: 100vh;
background-color: #e6e6e6;
mix-blend-mode: difference;
z-index: 1;
`;
let darkPdfDiv = document.createElement('div');
darkPdfDiv.setAttribute("style", darkPdfDivStyles);
document.body.appendChild(darkPdfDiv)
```
EDIT: I ended up switching to Buttar's extension myself, but in case people still want this one I'll leave it up. If anyone wants to use my logo, it's public domain no attribution required (no warranty). Code is GPLv3.

- (2025-06-16) Mark: Maybe I missed some of the instructions, as I'm no Chrome expert, but I couldn't get it to work.
- (2025-06-14) Costas Philippides: A lot of conditions to worry about until the pdf displays with dark background. Simply put, it doesn't work right outside the box.
- (2025-05-15) Jenil: Thank you
- (2025-05-12) Yap YH: It still doesn't work even after enabling the "Allow access to file URLs" in setting. "
- (2025-04-15) Luka Solncev: Not work
- (2025-03-27) Daniel Puia: It works fine, but you need to give more permissions to it that doesn't come as default on the Chrome Browser. Also, a toggle option would be nice to have for PDFs that you need to view in the original color scheme.
- (2025-01-13) Harigajan Panchalingam: Perfect, just missing a toggle functionality
- (2024-12-26) Undefined Undefined: Thank you
- (2024-12-24) AbuFahad: is not working
- (2024-12-18) Meghraj Baria: Works well. Thanks for this extension!
- (2024-12-03) Jean-Pierre Soso: Not working
- (2024-11-26) Yoav Wasserman: great extension, would love to see on/off button, I have to review some of the pdfs in their original color
- (2024-09-17) Hit Vaghani: as a developer, I appreciate your work but it can not differentiate between text and image it also changes the color of an image in my pdf (i am using Brave).
- (2024-09-16) João Rafael: thank you keep up the good work
- (2024-03-17) Diogenes Zzz: Disgusting!
- (2024-03-07) Sabrina Ergert: I have given permission for this extension to access file URLs by checking the box. Nevertheless, nothing happened when I opened a PDF file in the browser from the hard disk in my PC. I think it is a great pity that the advertised function does not work. For this reason, there is unfortunately only one star from me in the rating of this extension.
- (2023-11-20) Alexis Brissard: "Your PDF viewer should be set to light theme for this extension to work." How do you do that in chrome ?
