You can change your iMessage background on iPhone and Mac, but the steps differ between devices and iOS versions

iMessage does not have a single background setting that applies to all conversations. Instead, you customize the appearance of individual chats or use your device's system settings to change how message bubbles look. On iPhone running iOS 17 or later, you can set a custom background for a specific conversation. On Mac, your options are more limited — you can change the overall appearance through system settings, but not per-conversation backgrounds. Older iPhone models may not support chat backgrounds at all.

The process takes less than a minute once you know where to look, but the location of these settings is not obvious because Apple spreads them across different menus depending on your device and software version.

Key Takeaways

  • iPhone with iOS 17 or later lets you set a custom background for individual iMessage conversations by opening the chat, tapping the contact name at the top, and selecting "Edit Chat."
  • You can choose from Apple's built-in backgrounds, upload a photo from your camera roll, or use a solid color for each conversation separately.
  • Mac users cannot set per-conversation backgrounds; you can only adjust the overall message bubble appearance through System Settings under Appearance.
  • Older iPhone models running iOS 16 or earlier do not support custom chat backgrounds in iMessage.

Changing the background on iPhone with iOS 17 or later

Open the iMessage conversation you want to customize. Tap the contact name or group name at the very top of the screen — this opens a panel showing conversation details.

Look for the "Edit Chat" button near the top of this panel and tap it. You will see options to customize that specific conversation. Tap "Chat Color or Photo" to access background choices. Apple shows you several preset backgrounds (solid colors and gradients), but you can also tap "Add Photo" to use an image from your camera roll or take a new photo.

Once you select a background, tap "Done" to save it. This background applies only to that conversation — your other chats remain unchanged. You can repeat this process for any conversation you want to customize.

Using built-in backgrounds versus custom photos

Apple's preset backgrounds are solid colors and color gradients designed to work well behind message text. These load instantly and do not slow down your phone. If you choose a preset, the background appears behind all messages in that conversation, both yours and the other person's.

Custom photos from your camera roll give you more control but can sometimes make text harder to read if the image is too busy or too dark. If you use a photo, test it by sending a few messages to make sure you can still read the text clearly. You can always go back and switch to a different background if the photo does not work well.

If you change your mind about a background, open the conversation again, tap the contact name, select "Edit Chat," and choose a different option or tap "Remove Photo" to go back to the default.

What to do if you have an older iPhone or Mac

If your iPhone runs iOS 16 or earlier, the "Edit Chat" option does not exist. iMessage on these devices does not support custom per-conversation backgrounds. Your only option is to update to iOS 17 or later if your phone model supports it. Check Settings > General > Software Update to see if an update is available.

Mac users do not have per-conversation background options at all, even on the latest macOS versions. You can change the overall appearance of message bubbles by opening System Settings, clicking General, then Appearance, and choosing Light or Dark mode. This affects all your conversations but does not let you customize individual chats.

Troubleshooting when backgrounds do not appear

If you set a background but it does not show up, force-close iMessage and reopen it. Swipe up from the bottom of the screen (or use the app switcher) to close iMessage completely, then tap the iMessage icon again to relaunch it.

If you uploaded a photo and it appears blurry or distorted, the image may be too large or in an unsupported format. Try using a different photo or one of Apple's built-in backgrounds instead. If the background disappears after you restart your phone, your iOS version may not fully support the feature — check that you are running iOS 17 or later.

Custom backgrounds are stored locally on your device. If you sign into iMessage on a different iPhone, the backgrounds you set on your old phone will not transfer over. You will need to set them again on the new device.

Why the other person does not see your custom background

When you set a custom background for a conversation, only you see it on your screen. The other person sees their own default iMessage appearance. This is by design — backgrounds are a personal customization, not something you send to the other person. Think of it like changing the color of your notebook; it does not change what the other person is reading.

This means you can use backgrounds to organize your chats visually without affecting how the conversation looks on the other end. If you want both people to see a custom appearance, that would require a different messaging app with shared theme options, which iMessage does not offer.

Frequently Asked Questions

Can I set a background for a group chat?

Yes. The steps are identical — open the group conversation, tap the group name at the top, select "Edit Chat," and choose your background. Each group chat can have its own background, separate from your one-on-one conversations.

Will my background stay if I delete and reinstall iMessage?

No. Backgrounds are stored on your device, not in your iCloud account. If you delete iMessage or reset your phone, you will lose all custom backgrounds and need to set them again.

What iOS versions support chat backgrounds?

iOS 17 and later. If you have iOS 16 or earlier, the feature is not available. Check Settings > General > Software Update to see if your iPhone can update.

Can I use a video or animated image as a background?

No. iMessage backgrounds must be still images or solid colors. Videos and animated GIFs are not supported.

Does setting a background use a lot of storage?

No. Backgrounds take up minimal space. Even if you set custom backgrounds for dozens of conversations, the storage impact is negligible.
