If you have an iPhone, you can recover messages and files deleted from WhatsApp with WhatsApp Recovery, an app that's easy to use for any level of user. 

Recover them directly or with the iTunes backup

You could lose your WhatsApp messages for one of many reasons: accidental deletion, an update that has overwritten conversations, or maybe even a jailbreak problem.

In these situations, all is not lost: you can still get them back with the help of WhatsApp Recovery.

The program offers two options: direct, by scanning the memory of the device connected to the computer, or by using an iTunes backup of your iPhone.

In the latter case, the software will analyze the contents of the backup and let you extract and save to your PC contacts and conversations from WhatsApp (in XLS, TXT or XML), including multimedia file attachments (photos and videos).

Additionally, under the Tips section, there's a practical tutorial with questions and answers to let you make the most of WhatsApp Recovery.
