Share your screen with Slack Calls

Meetings are meant for sharing ideas, so make sure yours are seen. With the Slack desktop app, hop on a Slack Call and:

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

A note for Mac users: To use screen sharing, make sure you've downloaded the Slack app from our website. Screen sharing features will not be available from the App Store version.


Step 1: Start a call

  1. From either a channel or DM, click the  phone icon at the top of your screen.
  2. From a DM your call will start right away. From a channel, click Start new call to post it to the channel.

Tip: Check out Make calls in Slack for more in-depth instructions. And while you're at it, review some of the basics of Slack Calls.📞🙌


Step 2: Share your screen

Present your screen

During a call, any participant can present their screen by clicking the   Share your screen icon.Present_your_screen.png

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.

Tip: Take a look at all the actions you can take when you're on a call.


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 view your teammate's shared screen, but you won't be able to start a screen share from your end. To share your own screen, you'll need to switch to the Slack app for Mac or Windows.

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.
