Facebook emojis appear for users of the Facebook website, Facebook Android app, Messenger for web, Messenger for Android, and Instagram direct messages on web. Facebook apps for iOS use native emojis for their respective platform instead of Facebook's own emoji images.

Support for Emoji 15.0 is available for global Facebook users.

Facebook provides animated “emoji” reactions to posts. Reactions do not correspond to specific emojis in the Unicode standard, but approximate these characters:

👍 Like — Thumbs Up

❤️ Love — Beating Heart

😂 Haha — Laughing Face

☺️ Yay — Smiling Face (discontinued)

😯 Wow — Surprised Face

😢 Sad — Crying Face, showing an animated tear

😡 Angry — Red / Angry / Pouting Face

In March 2020, Facebook added a Care emoji reaction as an additional option in response to COVID-19. This is displayed similarly to a hugging face holding a red love heart.

This Care emoji is not available as a standardized Unicode emoji, and can only be used in reactions to Facebook posts.

Facebook has an emoticon implementation which uses Facebook-specific codes to show a color emoticon, as well as an extensible sticker collection.
