"Voice messages spent me 10GB+ storage every years and its definitely useless. Is it able to delete all voice messages from WhatsApp in iPhone?"
- From Reddit
Privacy and security have become key concerns in today's era of information explosion and advanced communication technologies. WhatsApp, one of the most widely used instant messengers, allows users to send text messages, voice messages, photos, videos, and more. However, to protect your privacy, it is important to permanently delete sensitive WhatsApp data, such as voice messages on iPhone, before handing your device to others. This ensures that no one can access your personal information without your consent. In this article, we will show you secure and effective methods to delete WhatsApp voice messages on iPhone.

If you only want to remove specific WhatsApp voice messages without affecting other chats, use the in-app selective deletion feature. This method is quick and suitable for daily cleanup, though it only deletes the messages from your device (or both devices within a time limit) rather than permanent erasure.
Here are the steps to delete a specific WhatsApp chat:
Step 1. Open WhatsApp and navigate to the chat containing the voice message you want to delete.
Step 2. Press and hold the specific voice message until a menu appears.
Step 3. Tap the "trash" can icon.
Step 4. Choose "Delete for Me" to remove it from your device or "Delete for Everyone" to remove it from both your device and the recipient's device.

Note: "Delete for Everyone" only works within WhatsApp's time limit (approximately 68 hours after sending). Once deleted for everyone, the message will be replaced with "This message was deleted". This method is suitable for occasional cleanup without affecting the rest of your chat history.
When you need to free up significant storage space or clear all WhatsApp data (including voice messages), deleting the entire chat history is an efficient solution. This method can target a single chat or all chats, and you can choose whether to retain media files.
How to remove all WhatsApp chat history on iPhone?
Step 1. Run WhatsApp app on an iPhone and tap "Settings" on WhatsApp app.
Step 2. Tap "Chats" > "Clear All Chats" option.
Step 3. Enter your phone number to confirm your action.
Step 4. Tap the "Clear All Chats" option to start deleting all chat history on iPhone WhatsApp, including the WhatsApp voice messages.

Standard deletion methods (such as in-app removal) only hide WhatsApp voice messages rather than erasing them completely. These files can still be retrieved by professional data recovery tools, which is risky if you plan to sell, donate, or lend your iPhone. To ensure 100% unrecoverable deletion, Coolmuster iOS Eraser is the optimal choice. This professional tool uses military-grade data overwriting technology to permanently wipe WhatsApp voice messages and other data, leaving no trace for recovery.

03When prompted, type "delete" to confirm, then click "Erase" again. A final confirmation window will appear, click "OK" to begin the permanent deletion process.

04Once the process is complete, all data on your iPhone will be permanently erased and unrecoverable. Your device is now ready to be set up as new.
