Prep the Noun Project app

Open up Noun Project for Mac on your desktop. Change the file format to PNG. Change the PNG size to 84px because Slack doesn’t allow you to upload images larger than 128px.

Customize your workspace

Next, open up Slack. From the main menu select Customize Slack. Then select the Emoji tab. Depending on your team’s settings, you may need administrative privileges. In the text box under 1) Choose a name: type the name that you will use to add the emoji into a message.

Once you find an icon that works well with the name you chose, drag and drop it on the Choose file button. Click the green Save New Emoji button at the bottom and your new emoji will be saved. Easy as cake, err, sandwiches!
