Before we get into the matter and see how to delete WhatsApp messages without leaving a trace, I would like to provide you with some preliminary information that will be useful for you to have a clearer picture of the situation.
In this case, I want to tell you that the only way to delete messages from WhatsApp chats without any trace of them is to activate the setting of the ephemeral messages. Once this is active for a chat, in fact, the messages sent in it are removed permanently and without leaving traces after one week from their sending (therefore without the appearance of words such as "deleted message" in their place).
It must be said, however, that the activation of this setting is reported to one's interlocutors and that the messages disappear after a week, so in the meantime they could be saved in other ways, for example through a trivial screenshot, by others. users.
Alternatively, there is the classic function of deleting messages within an hour of sending, introduced by WhatsApp since the early days but which, when used, leaves a trace of deleted messages (which are replaced by a statement relating to the fact that have been eliminated). Having clarified these points, we can proceed.
