How to enable dark mode for PDF files automatically in Microsoft Edge

Thanks for reaching out. My name is, Zadee. I'm an Independent Advisor and a Microsoft user like you. I'll be glad to help you today.'

That feature exists and it's free.

Once you set edge to dark mode, that should automatically apply when you open it up again. Be sure you have set it to dark mode and not system though.

-Open Edge

-Copy this to its URL: edge://settings/?search=dark <Enter>

-Select Dark

-Theme: Select Dark and Stormy

-Close edge.

If you already have all of this setting setup and it's still reverting back to light mode, try resetting edge.

-Open Edge

-Copy this to its URL: edge://settings/reset <Enter>

-Click Restore settings to their default values

-Click Reset

Let me know how that goes.

Before talking to you, I used this method and it did not work. As you can see, the PDF file is still white

I can right click on the PDF file and then Inspect then Console and then paste this command and press Enter

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);

But when I restart Chrome everything goes away and I have to repeat the steps again

I thought you were using Edge. If that's chrome and you have already set up dark mode in settings, reset chrome by putting this in the URL box.

chrome://settings/reset

>Restore settings to their original defaults

>Reset setting

If that does not work for you, can you try making your Windows System dark mode and see if these browsers follow the system setting? I have mine as dark mode in the system, edge, and chrome follow this setting, and opening a pdf file open in dark mode as well.

I did not tell you that I use Chrome, but I told you that I use Edge. My words are clear

This method does not work while my laptop is in dark mode

Once again my question is

How do I make any PDF file I open from Edge be in dark mode or (invert colors) automatically?

-Make sure your Windows is up to date.

-Try reinstalling your GPU drivers and restart the computer

Also, run a SFC scan and DISM to fix possible corrupted system files.

1. Press Win + Q
2. Type: command prompt > Right-click and Run as admin
3. Copy, paste, and enter these commands:

DISM.exe /Online /Cleanup-image /Scanhealth <Press Enter>

DISM.exe /Online /Cleanup-image /Restorehealth <Press Enter>

4. Once Step 3 is done, type this command:

sfc /scannow <Press Enter>

5. Restart the computer

If that does not fix it still, run an in-place repair.

This will not delete any data or reset your windows, this will simply correct corrupted system files in your computer.
