WhatsApp is one of the most popular messaging apps globally, but its default theme can sometimes feel monotonous. Luckily, WhatsApp allows some customization options, enabling users to change themes and personalize their chats. In this article, we’ll explore various ways you can change the theme on WhatsApp, including both official and unofficial methods.
Changing the Theme Using WhatsApp’s Built-in Dark Mode
WhatsApp does not currently offer a wide range of themes, but it does provide a dark mode that helps reduce eye strain and saves battery life on OLED screens. Activating dark mode is simple:
- Open WhatsApp on your phone.
- Tap on the three-dot menu in the top-right corner and go to Settings.
- Select Chats.
- Under Theme, choose between Light, Dark, or System Default.
By selecting “System Default,” WhatsApp’s theme will change based on your phone’s system settings.
Customizing WhatsApp Wallpaper
If you’re looking for more customization, WhatsApp allows you to change chat backgrounds. Here’s how:
- Open WhatsApp and go to a chat.
- Tap the three-dot menu and select Wallpaper.
- Choose from Bright, Dark, Solid Colors, or use your own Gallery images.
- Adjust the brightness, preview the wallpaper, and tap Set Wallpaper.
This customization helps make your conversations feel more personalized.

Using Third-Party Apps for More Themes
While WhatsApp does not officially support custom themes, third-party apps like WhatsApp Mods (such as GBWhatsApp and FMWhatsApp) allow users to implement different themes. These modified versions of WhatsApp offer:
- Fully customizable themes.
- Different colors, fonts, and icons.
- Additional privacy and security features.
However, using modded versions of WhatsApp comes with risks:
- They are not endorsed by WhatsApp, increasing the risk of account bans.
- Some mods may contain security vulnerabilities that could expose your data.
- Updates are not guaranteed, leading to potential compatibility issues.
If you choose to use mods, proceed with caution and download from trusted sources.
Changing WhatsApp Theme on Android Using Themes Apps
For users who prefer to stay on the official version of WhatsApp but still want customization, theme apps can be a great workaround. Apps like Nova Launcher and Substratum allow users to change WhatsApp themes indirectly by modifying the phone’s UI elements.
Steps to Use Substratum for a Custom WhatsApp Theme:
- Download and install Substratum Theme Engine from the Google Play Store.
- Find a compatible Substratum WhatsApp theme.
- Apply the theme and restart WhatsApp.
Note: Some features may require rooted devices for full functionality.
Customizing WhatsApp Icons
Another way to give WhatsApp a fresh look is by changing its icon. Many Android launchers, such as Nova Launcher and Apex Launcher, allow users to customize app icons.
Steps to Change the WhatsApp Icon:
- Install a custom launcher like Nova Launcher.
- Download an icon pack of your choice.
- Long-press the WhatsApp icon and select Edit.
- Choose a new icon from your preferred icon pack.
While this does not change the app’s internal theme, it enhances the overall look of your phone’s UI.

Final Thoughts
Although WhatsApp does not provide extensive theme customization options like some messaging apps, there are several ways to personalize your experience. Built-in features such as dark mode and custom wallpapers allow some level of personalization. For more advanced themes, you can explore third-party apps, but remember the security risks involved.
Hopefully, this guide has provided you with helpful insights on how to change your WhatsApp theme. Whether you choose official methods or external apps, you can now make WhatsApp feel more unique to your style and preferences.
