Delete Messages by Date. Tap the date header in any 1-on-1 cha | Telegram Tips

Delete Messages by Date. Tap the date header in any 1-on-1 chat to select a day or range of dates and delete all messages sent and received during that period.

Deleted messages are permanently erased and can be removed only for you or for both sides – if you’d like messages to automatically delete themselves for both sides, enable auto-delete in any chat.
