Share your screen with Slack calls

Meetings are meant for sharing ideas, so make sure yours are seen. Hop on a Slack call to do the following:

  •   Present your screen
  •   Draw on your screen
  •   Let others draw on your screen

Note: Drawing when screen sharing is only available on the Slack app for Mac and Windows.

Step 1: Start a call

From a channel

From a DM

  1. Open a channel, then click the channel name in the conversation header. 
  2. Click  Start a Call.  
  3. Click Start Call
  1. Open a DM.

Step 2: Share your screen

Present your screen

During a call, any participant can present their screen by clicking the   Share your screen icon. You can select your full desktop or a specific application window to share, then click Share.Slack call showing the option to share your screen while on the call

Allow others to draw on your screen

By default, your teammates can draw on your screen while you're presenting. To turn this off, click the   group drawing icon. You can also draw on your screen by clicking the   pencil icon. Use this tool to draw attention to specific sentences, charts, data points, or whatever else is important to call out.

Note: When you're sharing a specific application window, you won't be able to allow others to draw on your screen, or draw on your own screen.

Step 3: Review screen sharing tips

Take turns

During a call, only one person can share their screen at a time. When you're done presenting, the next person can start sharing to take control. Yay teamwork!

Active Speaker

The member sharing their screen becomes the active speaker by default: other teammates on the call will only see the active speaker's screen, even when others are talking.

Google Chrome

If you use Slack in Google Chrome, you can choose if you'd like to share your entire screen, a single application window, or a specific Chrome tab. You won't be able to allow others to draw on your screen, or draw on your own screen. 

Windows 7

Screen sharing in Slack requires transparent windows, but these are unavailable with some Windows 7 desktop themes. Here's how to make sure you’re using transparent windows:

  1. From your Windows desktop, choose Start.
  2. Select Control Panel.
  3. Choose Personalization and select any Aero theme.
