WhatsApp mods, also known as WhatsApp modifications, are unofficial versions of the popular messaging app WhatsApp. These modified apps are created by independent developers and offer users extra features and functionalities not found in the official WhatsApp application. These added features often include customization options for changing the app's appearance, advanced privacy settings, improved media-sharing capabilities, and more extensive group controls.

However, it's important to note that using WhatsApp mods comes with potential risks, such as security vulnerabilities and the possibility of violating WhatsApp's terms of service, which could result in account bans. Users should exercise caution when considering the use of WhatsApp mods and be aware of the potential consequences associated with them.
