Overview

• Android launches with six languages—English, Spanish, Hindi, Portuguese, Russian, and Arabic—and offers an option to auto‑translate entire chats.
• iPhone supports translations in more than 19 languages at launch via Apple’s translation system, with per‑message translation rather than automatic threads.
• The feature works in one‑to‑one chats, group conversations, and Channel updates without sending message content to WhatsApp servers.
• Users can long‑press a message to tap Translate and can download language packs on Android for offline use.
• The rollout is gradual across both platforms, with more languages to follow and no announced timing for WhatsApp Web or desktop support.
