Viber, as a widely used instant messaging app, allows users to send text, images, voice messages, and more. Over time, chat history can accumulate, impacting phone storage space or making the interface cluttered. Deleting unnecessary Viber messages can help you free up space, protect your privacy, or simply tidy up your chat history. This article will provide a detailed guide on how to delete Viber messages, offering several different methods.

Sometimes, you may just need to delete a message that was sent by mistake or that you don't want to keep. Viber provides a very convenient way to do this. Here are the steps to delete a single Viber message:
Step 1. Open the Viber app on your device.
Step 2. Tap the search icon and enter the name of the person whose chat you want to delete. Then, tap on their contact to open the conversation.
Step 3. Press and hold the message you want to delete. From the options that appear, select "Delete", and then choose one of the following:

Tips: To delete Viber messages for everyone, you must be the sender of that message.
Group chats are a key feature of Viber, enabling you to communicate with multiple people in one conversation. Here are two methods for deleting a group chat on Viber.
If you want to delete a single message or select messages within a group, follow the steps below based on the device you're using:
Step 1. Open Viber on your smartphone and go to the group chat where you've previously sent the message.
Tip: You can use the search icon to quickly locate the group.
Step 2. Tap and hold the message(s) you want to delete, then select the "Delete" option. You can also select multiple messages and tap "Delete".
Step 3. You'll be given the option to delete the message either for yourself or for everyone. Choose your preferred option to remove the message for just yourself or for the entire group.
If you want to leave a group and delete your message history, follow these steps:
Step 1. Open the Viber app on your phone and go to the group chat where the message you want to delete is located.
Step 2. Tap the "three-dot" icon at the top of the screen and select "Chat info" from the options.
Step 3. Scroll to the bottom and tap "Leave and delete". In the pop-up, confirm by selecting "Leave and Delete" again.

When you no longer need the entire chat history with a contact, you can delete the whole conversation. This method is more efficient than deleting messages one by one and is ideal for organizing your chat list or freeing up space.
For iPhone users: Open Viber and swipe left on the chat you want to delete. Tap on the "Delete" option and confirm your choice.
For Android users: Open Viber and press and hold the chat you want to delete. A pop-up with several options will appear—tap on "Delete" and confirm to remove the conversation.
If you want to completely clear all chat history in Viber, you can use the following method:
Step 1. On the main screen of the Viber app, look for the "..." icon in the bottom-right corner (for iPhone) or the "three horizontal lines" (for Android), which is the "More" tab. Tap on it and go to the "Settings" menu.
Step 2. In the Settings menu, find "Calls and Messages" and tap on it. You'll see the "Clear Message History" option.
Step 3. When you tap this option, a Delete History window will appear with two choices: "Clear" and "Cancel.
Step 4. Select "Clear" to confirm the deletion of your message history. This will remove all messages from every conversation on your device. Note that this will only delete your message history, not the history of other participants. If you change your mind, tap "Cancel" to go back.
