Share your screen with Slack calls

Meetings are meant for sharing ideas, so make sure yours are seen. With the Slack desktop app, there’s a lot you can do on a Slack call with a click of a button:

  •   Present your screen
  •   Share control of 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.ISS-img01.png

Allow others to draw on your screen

While presenting your screen, you can enable the drawing tool for your teammates to use: just click the   pencil icon. Other call participants can use this tool to draw attention to specific sentences, charts, data points, or whatever they’d like to call out.

Share control of your screen

If you're using the Slack desktop app on Mac or Windows, you can also click the   pointer icon. Each call participant will have their own cursor and the ability to control what’s on the screen.

As we prepare to roll out a new, faster version of Slack calls in early July, we will be removing the ability to share control of your screen. You can learn more about this change and find a list of alternative options here.

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

Clipboard Sharing

While another member is sharing control of their screen, any text you copy to your local clipboard will also be sent over to their computer. This allows you to paste your text on their screen, if you'd like. This makes collaborating easier, but there are some security risks to keep in mind:

  • Anything you copy will be sent to the other person’s clipboard, even if you decide not to paste the copied content on the shared screen.
  • If the member sharing their screen has a clipboard management tool installed, the content you copy will be stored for later access.

Note: During a screen share, we'll always ask you to confirm before sending over clipboard content for the first time.

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.
