You can delete iMessages one at a time, in bulk, or set them to vanish automatically

Deleting an iMessage depends on what you want to remove. You can delete a single message from a conversation, wipe out an entire thread, or set messages to disappear after a set time. The steps differ slightly between iPhone, iPad, and Mac, and the option you choose affects whether the other person sees that you deleted something.

The most common reason to delete is to clear space on your device or remove a message you sent by mistake. iMessages don't take up much storage compared to photos or videos, but if you have years of conversations, clearing old threads can help. If you delete a message you sent, the other person still sees it on their end — deletion only removes it from your device.

Key Takeaways

  • On iPhone and iPad, press and hold a single message, then tap Delete; on Mac, right-click the message and select Delete.
  • To delete an entire conversation, swipe left on iPhone or right-click on Mac, then choose Delete.
  • Turning on "Disappearing Messages" in a conversation settings makes all new messages vanish after 2 minutes, 15 minutes, 1 hour, or 1 day.
  • Deleting a message from your device does not remove it from the other person's phone — they will still see it unless they delete it themselves.
  • Once deleted, a message cannot be recovered unless you have a backup of your device from before the deletion.

Deleting a single message on iPhone or iPad

Press and hold the message you want to delete until a menu appears. Tap the trash can icon or the word "Delete" — the exact wording depends on your iOS version. The message disappears from the conversation when ready.

If you change your mind within a few seconds, you can undo the deletion by shaking your device or tapping Edit > Undo at the top of the screen. After a few seconds pass, the undo option closes and the message is gone for good.

Deleting a single message on Mac

Right-click or Control-click the message in the conversation. A menu appears with the option to Delete. Click it, and the message is removed from your Messages app.

On Mac, you can also select a message and press the Delete key on your keyboard. The effect is the same — the message leaves the conversation on your device only.

Deleting an entire conversation

On iPhone and iPad, swipe left on the conversation thread in your Messages list. A red Delete button appears. Tap it to remove the entire conversation and all its messages from your device.

On Mac, right-click the conversation in your list and select Delete Conversation. The thread and all its contents disappear from your Messages app. This action does not notify the other person, and they still have the conversation on their end.

Setting messages to disappear automatically

If you want messages to vanish without you having to delete them manually, use Disappearing Messages. Open a conversation, tap the person's name or number at the top, scroll down, and tap "Disappearing Messages." Choose a time window: 2 minutes, 15 minutes, 1 hour, or 1 day. From that point forward, every new message in that conversation — from both you and the other person — vanishes after the time you set.

Disappearing Messages only affect new messages sent after you turn the feature on. Old messages in the conversation stay until you delete them manually. The other person sees the same disappearing timer on their end, so they know messages will vanish. This feature works on iPhone, iPad, and Mac as long as both people are using iMessage (not SMS or MMS).

What happens when you delete a message the other person already saw

If you delete a message you sent, it vanishes from your device but remains on the other person's phone. They can still read it, screenshot it, or forward it. Deletion is a one-way action — it only affects your copy of the message.

There is no way to unsend or recall an iMessage once the other person has received it, even if you delete it when ready. If you need to take back something you said, your only option is to send a follow-up message explaining or correcting what you wrote.

Recovering a deleted message

Once you delete a message, it cannot be recovered through the Messages app itself. Your only path to recovery is a device backup made before the deletion. If you back up your iPhone or iPad to iCloud or a computer, you can restore from that backup to get deleted messages back — but restoring a backup overwrites your entire device with the older version, so you lose any changes made since the backup was created.

For most people, this trade-off is not worth it. If a deleted message was important, ask the other person to send it to you again or screenshot it from their phone.

Frequently Asked Questions

Does the other person know when I delete a message?

No. Deleting a message from your device does not send any notification to the other person. They see the message on their phone as if nothing happened. The only exception is Disappearing Messages, where both people see the timer counting down.

Can I delete a message I sent but the other person hasn't read yet?

Deleting works the same way whether the message is read or unread — it only removes the message from your device. The other person still receives it and sees it, whether they have opened the conversation or not. There is no unsend feature in iMessage.

What's the difference between deleting a message and turning on Disappearing Messages?

Deleting removes a message you have already sent. Disappearing Messages is a setting you turn on for future messages, and both people see the timer. Use deletion for old conversations you want to clean up; use Disappearing Messages if you want new messages to vanish automatically going forward.

If I delete a conversation, can the other person still message me?

Yes. Deleting a conversation only removes it from your Messages list. The other person can still send you messages, and a new conversation thread will appear on your device when they do. Their messages are not affected by your deletion.

Will deleting messages free up storage space on my iPhone?

Deleting messages frees up a small amount of space, but iMessages themselves use very little storage. If you are running low on space, photos, videos, and apps take up far more room. Deleting old message threads helps, but clearing photos or removing unused apps will have a much bigger impact.
