Use dark mode in Slack

You can choose between a light and dark mode in Slack across your devices. Dark mode helps make working in Slack easier on your eyes by using a darker, higher-contrast colour theme. This preference is device specific — adjusting dark mode on the desktop app won’t sync with Slack on the browser or mobile app.


Adjust your dark mode preference

To turn on dark mode across your devices:

Desktop

iOS

Android

  1. From your desktop, click your workspace name in the top left.
  2. Select Preferences from the menu.
  3. Select Themes and click Dark.

Note: on devices running iOS 13, turn on dark mode in Slack from your OS settings. You won't see the option for dark mode in your Slack preferences.

iOS 12 and earlier

  1. Swipe left to open the right sidebar.
  2. Tap Settings.
  3. Toggle on Dark Mode.

iOS 13

  1. Open the Settings app on your iOS device.
  2. Tap Display & Brightness.
  3. Under Appearance, select Dark.
  1. Tap the  Overflow menu.
  2. Tap Settings.
  3. Under General, select Dark Mode.

Note: on devices running Android 9 and earlier, select Battery Saver if you’d like Slack to turn on dark mode automatically when your device goes into battery saver mode.


Sync dark mode with your OS settings

On the Slack app for Mac, iOS 13 or Android 10, you can sync dark mode in Slack with your operating system settings. This happens automatically on iOS 13.

To sync dark mode in Slack with your Mac or Android 10 OS settings:

Mac

Android

  1. From your desktop, click your workspace name in the top left.
  2. Select Preferences from the menu.
  3. Select Themes.
  4. Click the box next to Sync with OS Setting.

Note: if you can't see the preference to sync dark mode with your OS setting, make sure you're running the latest version of the Slack app for Mac.

  1. Tap the  Overflow menu.
  2. Tap Settings.
  3. Under General, select System default.

Other operating systems, like Windows and Linux, do not automatically switch between light and dark themes in Slack when your device does. This is something we’re working on — stay tuned!
