Emoji keyboards are built into most phones and computers, making it easy to add emoji to messages, emails, documents and social posts. You can also copy emoji directly from websites like Emoji.ac.
Emoji are useful when they add tone or meaning that plain text may miss. A smile can soften a short reply, a heart can show affection, and a symbol can make information easier to scan.
For websites and apps, emoji can be inserted as the emoji character itself or represented with Unicode and HTML formats when more control is needed.
