Emojis are small, digital images or icons used to communicate or express concepts such as emotions and physical gestures in your messages.
Select the icon inside the Mattermost message input box to open the Emoji Picker.
From Mattermost v6.1 and in Mattermost Cloud, react to messages quickly by selecting a recently-used emoji while hovering over a message. If your most recent reactions aren’t visible, you can enable quick reactions by selecting Settings > Display > Quick reactions on messages.
Alternatively, open the emoji autocomplete by typing
: followed by at least two characters of the word describing the emoji. Descriptions include skin tone details for people-based emojis, where supported.
It’s also possible to create your own custom emoji if the emoji you want to use doesn’t exist.
You can create Custom Emojis which are available to everyone on your Mattermost server. From the Emoji Picker, select Custom Emoji. Small, square pictures work best when selecting an image to upload. The file can be any JPG, GIF, or PNG and up to 1 MB in size.
Enter a name for your Custom Emoji. This is the name that will show up in the emoji autocomplete.
Choose Select, then select the image to use for the emoji.
Once saved, your emoji is added to the list of Custom Emoji.
If you can’t see the Custom Emoji option, then your Mattermost System Admin may have restricted access to certain users. Contact your Mattermost System Admin for help.
For further assistance, review the Troubleshooting forum for previously reported errors, or join the Mattermost user community for troubleshooting help.
To use your Custom Emoji in a message, simply type
: followed by your emoji name to bring it up in the emoji autocomplete. Other users on the site will also be able to see your emoji in the autocomplete, and will be able to use it in their own messages.
