IOS 27 Trick Enables Custom Backgrounds In IPhone Messages—But There’s A Catch

Your iPhone’s Messages app has a surprisingly useful customization feature that can completely change the look of your conversations. You can add custom photos, colors and dynamic backgrounds behind your iMessage conversations, turning an otherwise standard chat into something much more personal.

But there’s an important catch: the background isn’t private to you.

When you change a conversation’s background, other participants in that iMessage conversation can see it too—and they can change the background themselves.

How to Add a Custom Background

If you’re running a compatible version of iOS, setting a background takes only a few seconds.

Open the Messages app and choose an iMessage conversation.

Then:

Tap the person’s name or group icon → Backgrounds

You’ll see several built-in options, including:

Color
Sky
Water
Aurora
Photo

Select one and swipe through the available styles. For color backgrounds, you can also adjust the color using the available controls.

The result appears behind the messages in that conversation.

You Can Use Your Own Photo

This is where the feature gets considerably more interesting.

Choose Photo under Backgrounds and select an image from your Photos library.

You can then customize it before applying it. For example, you can:

Crop the image
Convert it to black and white
Apply a duotone effect
Add a color-wash effect
Adjust the image to better fit the conversation

You can even use a photo someone has already sent in the conversation. Touch and hold the photo, then choose Set as Background.

That means you could use a vacation photo, family picture, favorite landscape or even an AI-generated image as your chat background.

The AI Twist

If Apple Intelligence is enabled on your compatible iPhone, Apple also allows you to use Image Playground to create a unique image specifically for your Messages background.

This opens up much more creative possibilities.

Instead of choosing an existing photo, you could create a completely new visual style for a conversation.

Imagine a space-themed background for a group of friends, a minimalist gradient for work conversations or a cartoon-style background for a family chat.

Here’s the Catch

There’s one thing you should know before getting too creative.

Conversation backgrounds aren’t just for you.

Apple states that people in the conversation can see the background, and participants can change it for the group.

So if you set a beautiful photo as your background, the other person will see it too.

And if someone else changes the background, that change affects the conversation for everyone.

This is quite different from wallpapers or themes that are normally controlled independently by each user.

For people who want a completely private visual customization, this could be disappointing.

You Can Turn Backgrounds Off

Don’t like the feature?

You can disable conversation backgrounds from:

Settings → Apps → Messages → Conversation Backgrounds

However, there’s another important detail: turning the feature off on your iPhone doesn’t necessarily mean other participants stop seeing the background they’ve selected. Apple says other people in the conversation can still see a background chosen for that conversation.

Removing a Background

If you want to return a conversation to its normal appearance, open the conversation and go to:

Contact/Group Icon → Backgrounds → None

Apple notes that removing a background affects all participants in the conversation.

So once again, it’s a shared setting rather than a personal theme.

Is This Really an iOS 27 Feature?

There’s some confusion around this feature because it has been associated with newer iOS releases and is sometimes described online as an iOS 27 trick.

However, Apple’s current documentation says conversation backgrounds are available in iMessage on iOS 26 and later, rather than being exclusive to iOS 27.

So if you’re running a compatible iOS 26 or newer version, you may already have access to it.

That’s good news if you’ve been waiting for iOS 27 just to customize your Messages conversations.

Why Apple Made It Interesting

Apple has historically kept Messages relatively controlled compared with apps such as WhatsApp or Telegram, where chat customization has been available for years.

Conversation backgrounds bring some of that personalization directly into Apple’s messaging ecosystem.

The combination of personal photos, visual effects and Image Playground makes the feature considerably more flexible than simply selecting a color.

But the shared nature of the feature is both its most interesting and potentially frustrating aspect.

Final Thoughts

If you want to make your iPhone Messages conversations more personal, custom backgrounds are definitely worth trying.

Go to:

Messages → Conversation → Contact/Group Icon → Backgrounds

From there, you can choose a color, dynamic background or your own photo. If Apple Intelligence is available, you can even create something unique with Image Playground.

Just remember the catch:

Your Messages background isn’t completely yours.

Everyone in the conversation can see it, and other participants can change it too.

That makes the feature feel less like a personal wallpaper and more like a shared chat theme—which could be either a fun collaboration or a recipe for chaos, depending on your group chat.
