How can I preview PDFs with Google Chrome in dark mode?
Paste this JavaScript code in your console:
var cover = document.createElement("div");
let css = `
position: fixed;
pointer-events: none;
top: 0;
left: 0;
width: 100vw;
height: 100vh;
background-color: white;
mix-blend-mode: difference;
z-index: 1;
`
cover.setAttribute("style", css);
document.body.appendChild(cover);

You can use the Dark Reader Google Chrome extension and used the Filter+
mode. It will work on the online PDF files, but not at the local PDF files.
