WhatsApp on PC currently supports syncing with your mobile app and can be used on Windows, macOS, and the web; the desktop app links up to four devices and can function without your phone being online in some setups. It has introduced reactions in voice chats, a dedicated media tab for easier search across chats, and a refined link-preview experience, with ongoing updates to performance and usability; updates also include improved group call speaker prioritization and expanded Status stickers and interactions. This summarizes latest available desktop PC behavior and notable feature shifts.
