Custom Slack emoji brighten my workday. Here's how to make your own

Slack power users might already know about this fun little Easter egg.

With Slack, you can make an emoji for any situation.

Chatting with coworkers on the Slack productivity app for desktop or phone has become a way of life. While being helpful for work communication, the software isn't without its Easter eggs, like the ability to create custom emoji to go with the 2,000-plus emoji that are already in there. Big whoop, right? But trust me, start making and using custom emoji and your Slack cred will soar. All Slack members can make emoji, but not Slack guests. The feature is available on Free, Standard, Plus and Enterprise Grid plans.

Making a new emoji for Slack is easy and addictive. Add this skill to your arsenal to show off how much better you are at Slack than your coworkers 😉.

Can I make a Slack emoji on the mobile app?

You can't make custom emoji from your phone, but you can access the custom emoji you made on the desktop from mobile. Your emoji will be sandwiched by two colon punctuation signs, so to conjure it on mobile, bookend the name with colons (e.g., :cat:)

Slack also notes that some workspaces won't let you make custom emoji. I know, it's a bummer. If you're not sure, you can contact your workspace or org owner.

Here's how to make a custom emoji on the Slack desktop app

1. Open Slack.
2. Click your workspace name in the top left corner.
3. Click Customize Slack.
4. Click Add Custom Emoji.
5. Upload an image and name it.
6. Click Save.

What to do with a Slack emoji once it's live

A well-placed emoji can spice up your work conversations and let you react to activity. Some are almost meme-worthy. Sprinkle them into responses in conversation, and add as a reaction to a message in one of your channels. Choose the emoji or manually type in the code in the message field to use it as a response. To react to someone else's Slack message with an emoji, hover over the message with your cursor and click the smiley face option. From there the emoji library will open.

How do I search for a custom emoji?

You can go back in after you've made the emoji and search for it by name. You don't need to add the colons to search for your emoji. You can also scroll through everyone else's creations for inspiration.

Can I delete my custom Slack emoji?

Don't worry. If you messed up, it's not there forever. Simply click the "X" to get rid of your Slackmoji. You can't get rid of anyone else's though. If there's a particularly inappropriate emoji, Slack says you can contact an administrator to have it removed.
