Grayscale Tool
Item media 1 screenshot


Press shift+g (or create your own key shortcut) to (de)activate grayscaling of a web page.

Originally intended for web designers who might want to test the contrast of their content by changing to grayscale, but this extension can really be used by anyone who for some reason want to remove the colors of a web page. The grayscale persists between page loads, and the key shortcut to activate can be customized in the options.

Works well, I would prefer it to store on/off state per tab since I'll only need it for one or two tabs at a time but for my usage I only activate it briefly now and then so I don't need to worry much about opening/refreshing other tabs while its on. I'm using Alt+G as the shortcut as I already use Shift+G for something else.

Doesn't work anymore. You can set the shortcut to anything, but pressing the shortcut doesn't turn anything greyscale. Maybe it needs to be updated.

No matter what combination I used, it didn't work- was looking forward to this...
