Facebook launched stickers for its mobile apps in May, and now it has introduced them to web in Messages. 

Facebook's beloved - and somewhat quirky - stickers first appeared within Facebook Home. They are similar to emojis made popular in texting, only they are much bigger and can include animations. Facebook has pre-loaded two sets of stickers for web, including smileys and cats, at launch. 

To add a sticker with a web browser on desktop, log into Facebook and tap the smiley icon in the compose box of Messages.  Then select a sticker and tap to insert into the private conversation. A store is also available for those who want to buy premium stickers or download more free sets.

Check out Facebook's Messenger app to see the mobile version as well. The ability to add stickers is quite similar: tap the smiley in the text box, select one, and then tap to insert.

Facebook stickers are available on the web for at least some US-based users starting today. Let us know in the comments if the feature is live in the UK too.
