How to Delete All or Multiple Messages on iPhone: Complete Guide
TL;DR:
Want to delete all your iPhone messages but don't know where to start? This guide covers everything you need to know about deleting messages on iPhone:
- Check whether you can delete all messages at once and learn about the available options on iPhone.
- Delete multiple messages or conversations by selecting unwanted chats or individual messages.
- Remove all messages from iPhone manually or set your device to automatically delete old messages.
- Permanently erase messages with a professional data erasing tool to protect your privacy.
Over time, your iPhone may collect a large number of text messages, iMessages, photos, and attachments that you no longer need. These messages can take up storage space and make it harder to find important conversations. If you want to clean up your Messages app, you may wonder whether you can delete all messages on iPhone at once or remove multiple conversations quickly. In this guide, we'll walk you through different ways to delete all or multiple messages on your iPhone, including how to delete them permanently.

Part 1: Can You Delete All Messages on iPhone at Once?
Yes, you can delete all messages on your iPhone, but Apple does not provide a direct "Delete All Messages" button in the Messages app. If you have a lot of conversations to remove, you'll need to select and delete them manually or use the automatic message deletion feature.
Starting with newer iOS versions, you can quickly select multiple conversations in the Messages app and delete them together. However, if you want to remove every message from your iPhone, you may still need to repeat the process or adjust the message retention settings to automatically delete older messages.
Before deleting all messages, keep in mind that this action cannot be easily undone once the messages are removed from the Recently Deleted folder. If there are important conversations, photos, or attachments you want to keep, it's better to back them up first. (How to Back Up Text Messages on iPhone?)
Part 2: How to Delete Multiple Messages on iPhone
If you don't want to remove all messages from your iPhone, you can delete multiple conversations or selected messages instead. The Messages app allows you to clean up unwanted chats in just a few steps.
Method 1: Delete Multiple Conversations from Messages App
If you have many old conversations you no longer need, you can delete them in bulk from the Messages app. This will remove the entire chat thread, including the messages and attachments inside it.
Here's how to delete multiple conversations on iPhone:
- Open the "Messages" app on your iPhone.
- Tap "Edit" in the top-left corner.
- Select "Select Messages" from the menu.
- Check the conversations you want to remove.
- Tap "Delete" and confirm your action.

Note: On newer iOS versions, deleted conversations may be moved to the Recently Deleted folder. You can delete them there if you want to remove them permanently.
Method 2: Delete Multiple Messages Inside One Conversation
If you want to remove only specific texts, photos, or attachments from a conversation, you can select and delete multiple messages without deleting the entire chat. Follow these steps:
- Open the conversation in the "Messages" app.
- Touch and hold the message you want to delete.
- Tap "More".
- Select the messages you want to remove.
- Tap the "Trash" icon and confirm the deletion.

This method is useful when you want to free up space while keeping the rest of the conversation.

Part 3: How to Delete All Messages on iPhone
If you want to clear all messages from your iPhone, you can either delete conversations manually or let your iPhone remove older messages automatically. Choose the method that works best for your needs.
Method 1: Delete All Conversations Manually
The easiest way to remove all messages is to select and delete conversations directly from the Messages app. This method works well if you only have a limited number of chats to remove. Follow these steps:

Method 2: Automatically Delete Old Messages on iPhone
If you don't want to manually delete messages every time, you can set your iPhone to automatically remove older messages after a certain period. This is a convenient way to keep your Messages app clean and save storage space. Follow these steps:
- Open "Settings" on your iPhone.
- Scroll down and tap "Messages".
- Tap "Keep Messages" under the "Message History" section.

After setting this option, your iPhone will automatically delete messages older than the selected time period.
