Slack uses shortcodes such as :tada: and lets workspaces add custom emojis. Reactions are a quick way to acknowledge messages without adding noise to a channel.
Many teams agree on reaction meanings, such as 👀 for “looking at it” and ✅ for “done”.
Use your phone’s emoji keyboard, the system emoji picker on a computer (Win + . on Windows, Control + Command + Space on Mac), or copy any emoji from this site and paste it into Slack.
Press and hold a message and pick an emoji from the bar, or tap + to choose any emoji.
WhatsApp uses its own emoji designs on Android and the web, while iPhone users see Apple’s designs, so the same emoji can look different to sender and recipient.
Send one to three emojis on their own with no text. WhatsApp shows them larger automatically.
Edit your profile, tap the Bio field, and use your keyboard’s emoji key, or paste emojis copied from this site.
Emojis in captions can make posts easier to scan and add personality. Platforms index the words in captions, so keep important keywords as text.
Searching by emoji works in some places but is inconsistent. Hashtags and words are more reliable.
