So many workplaces and communities use Slack to communicate on a daily basis, whether it’s across time zones or across tables. What separates Slack from other messaging platforms is its dedication to making communicating fun. At the ❤️ of that experience is emoji. 👌

Many people don’t know you can customize your Slack workspace with custom emojiNoun Project is the peanut butter to Slack’s jelly, and adding custom icon emoji with Noun Project for Mac is just about as easy as making a PB&J.

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.

Tip: Set zoom to 50% to see what works well at small sizes

*If you are not a Mac user, you can always use, just download the PNG icon, and resize it smaller than 128px by 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.

Choose something that is easy to type and remember

Select an icon

Keep in mind the icon will be significantly reduced in size. Choosing icons that are completely solid, have high contrast, or thick lines tend to work the best at small sizes. 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!

Tip: You can always drag and drop onto file inputs on Mac

Try the dang thing out

Open up a new message with a coworker or friend. Type something witty and use the :name-you-chose: convention to add your new custom Noun Project emoji to your message. Easy peasy. You can also find it in the emoji list under Custom.
