WhatsApp is testing a new feature that allows users to access large stickers on their desktops. The larger stickers are available to a select group of beta testers who install the latest WhatsApp beta version on the Microsoft Store for Windows. 

This feature is not new as stickers are always sent in their larger format by default. Earlier this year, WhatsApp allowed iPhone users to create their stickers using their photos. The messaging platform also rolled out an in-app chat support feature on Windows for beta users. Additionally, WhatsApp introduced new icons for communities and their linked groups on Android beta.
