You can use our iCloud backup feature to back up and restore your chat history. WhatsApp chat histories aren't stored on our servers. Media and messages you back up aren't protected by WhatsApp end-to-end encryption while in iCloud. We can't retrieve any deleted messages for you.
To make a manual backup of your chats at any time, go to WhatsApp > Settings > Chats > Chat Backup > Back Up Now. You can also enable automatic, scheduled backups by tapping Auto Backup and then choosing your backup frequency. This will back up your chats and media to your iCloud account. You can choose to include or exclude videos from the backup. The iCloud backup process can take a while to complete, depending on your Internet connection and backup size.
If you're concerned about your cellular data usage, we recommend that you limit your iCloud to only back up on Wi-Fi.
If you've previously backed up your iPhone using iCloud or iTunes, you might be able to retrieve your WhatsApp chats by restoring your iPhone from a previous backup. For more information on backing up and restoring your iPhone, visit the Apple Support website.
You can email yourself a chat history if you'd like to save a chat:
