Facebook has now added Stickers to the web, so users can send them in private messages from their computers. The feature has been available in messages on the Facebook and Facebook Messenger apps for iOS and Android since Spring, and now it’s being greatly expanded to all of Facebook’s users.

“To send stickers, tap the smiley icon in your message; scroll across the top of the sticker window to find the pack you want to use and tap the sticker you want to instantly send,” a spokesperson for the company says in an email. “Tap the basket icon to visit the sticker store where you can find other fun icons.”

This is a pretty big deal, particularly if Facebook aims to turn this into a sponsorship business, as TechCrunch Facebook beat writer Josh Constine recently suggested.

Last week, Facebook launched some new stickers based on Mark Zuckerberg’s dog, Beast.
