Communication is an art, they say, and like any other art, it must change to fit the medium it inhabits. In a primarily textual medium like Slack, words may convey their meaning but they also tend to lose their tone. That’s why we have those tiny images everyone calls emojis.

Out of the box, Slack offers all of the emojis in the Unicode standard, but sometimes the usual list of emojis, as exhaustive as it is, just doesn’t cut it. For those instances, Slack users have the option to add their very own emoji to the mix or pick from a number of sets made specifically for the app. You can even set multiple alternative names for each of these emojis just to make remembering them easier.

How to Add Custom Emoji to Slack

Any member of your workspace can add custom emojis to it. There are some limits in place for these that bear mentioning, however. You may only upload JPG, PNG, or GIF formats with up to a maximum size of 128KB. Animated GIFs must be 50 frames or less in length. Slack recommends 128x128px square images. The app will automatically resize your image if it doesn’t match the recommended dimensions.

Emojis can only be added from Slack’s desktop and web apps.

1. Open the Slack app or website on your computer.

2. In the message field at the bottom, click the Emoji (smiley face) icon.

3. Click the Add Emoji button in the bottom-left corner of the Emoji menu.

4. Hit the Upload Image button and select your image.

6. Click Save.

How to Use Custom Slack Emoji

After a custom emoji has been added to your Slack workspace, you can find it by entering the name you chose for it in the emoji menu search bar.

Alternatively, you may add the new emoji to your messages on the fly by typing a colon (:) followed by its name. The app will show you matching emojis in a pop-up as you start typing in the name.
