Use this interactive demo to learn how to add a custom emoji to your Slack workspace.

Quick summary

Slack allows workspace admins to create custom emojis by uploading any image file and assigning it a unique name. Once added, the custom emoji appears under the Custom section of the emoji picker and can be removed at any time through workspace settings.

Steps

Navigate to the emoji option within your Slack workspace.
Click 'Add emoji' to open the custom emoji upload panel.
Upload your image or custom emoji file and give it a unique name to register it in the workspace.
After saving, locate your new custom emoji under the 'Custom' section of the emoji picker.
To delete the emoji, click on your workspace name in the top-left corner.
Go to 'Tools & settings' and select 'Customise workspace' from the menu.
Find your custom emoji in the list and click the cross button next to it to remove it.

📌 Why this matters

Creating custom emojis in Slack lets teams express their unique culture and brand identity directly within their day-to-day messaging. Custom Slack emojis improve engagement by giving team members expressive, workplace-specific reaction options that standard emoji sets don't offer. Workspace admins can upload any image as a custom emoji in seconds, making it easy to celebrate wins, reinforce inside jokes, or align communication with company branding. The ability to add and delete custom emojis at any time ensures workspaces stay relevant and clutter-free as team needs evolve.
