How to Create Custom iPhone Wallpapers in iOS 27

iOS 27 adds two genuinely different ways to create custom iPhone wallpapers: one that generates a brand-new image from a text description, and one that expands an existing photo to fit the Lock Screen naturally. This is a pre-release guide to both. The step sequences are reconstructed from WWDC materials, Apple developer documentation, and pre-release reporting; exact UI labels may shift before the final build ships this fall.

If you want a wallpaper you couldn't photograph, use Image Playground to generate one from scratch. If you already have a photo that keeps getting cropped in the wrong place, use the photo extension tool to let Apple Intelligence fill in the edges. Both paths start from the same place in Settings.

Before you start: device eligibility and availability

Neither tool works without Apple Intelligence. According to Apple's WWDC announcement this week, access arrives this fall with iOS 27 for users who enable Apple Intelligence on supported products set to a supported language. Apple has not published a wallpaper-specific compatibility list, so check your device against Apple's official eligibility page rather than assuming.

The language setting matters more than most people expect. Apple Intelligence is tied to device language, and an unsupported language will lock out the feature regardless of your hardware. To check: go to Settings > Apple Intelligence & Siri. If that section doesn't appear, your device or language configuration isn't eligible.

Two things remain unconfirmed as of this week: whether image generation happens on-device, in the cloud, or some combination; and whether generated wallpapers can be applied to the Home Screen as well as the Lock Screen. Apple's WWDC developer session references wallpapers and backgrounds "across the system," while MacRumors' coverage focuses specifically on the Lock Screen. Treat the Lock Screen as the confirmed surface; Home Screen support is possible but not established.

How the two tools work

Image Playground: generate a wallpaper from a text prompt

Image Playground, already used in iOS for generating custom emoji and images, is getting an upgrade in iOS 27 that brings it into the wallpaper flow. When choosing a new wallpaper, you'll have the option to generate something custom through Image Playground, and Apple Intelligence will produce an image based on your description and set it as your Lock Screen wallpaper, as MacRumors reported this week.

Worth noting: Apple is testing models that could produce more lifelike images for wallpaper generation than what Image Playground currently outputs elsewhere, according to earlier MacRumors reporting from last month. The wallpaper version of Image Playground may look meaningfully different from what you've seen in other iOS contexts, so calibrate expectations accordingly.

In practice, prompt specificity tends to matter. "Misty coastal cliffs at dusk, deep blue and slate, minimal detail" gives the model more to work with than "pretty ocean scene." Subject, mood, color palette, and stylistic direction are all useful inputs.

Use this tool when you want a wallpaper you couldn't take a photo of: a specific visual style, an abstract composition, a fictional scene, or simply something no photo in your camera roll captures.

Photo extension: expand an existing photo to fill the screen

The second tool takes a different approach. Apple Intelligence analyzes a photo you already have and generates content to fill the edges, so the image covers the full Lock Screen without cropping or letterboxing, MacRumors reported this week. It's the same concept as Photoshop's generative fill: the phone invents plausible surroundings consistent with the original image.

A safer bet is to start with photos that have simple or natural backgrounds: open sky, water, foliage, soft gradients. Those give the model room to extend convincingly. Portraits with tight framing or photos with intricate detail near the edges will produce less predictable results; the AI is inventing what isn't there, and complex borders give it less to go on.

Use this tool when you have a photo you want as a wallpaper but it doesn't fit the screen without losing something important.

Getting started: the shared entry path

Both tools follow the same opening sequence, which matches the existing wallpaper flow documented by Apple Support. Settings is the consistent entry point for all wallpaper changes in current iOS builds, and nothing in the pre-release reporting suggests iOS 27 changes that pattern.

1. Open the Settings app.
2. Tap Wallpaper.
3. Tap Add New Wallpaper. The wallpaper picker opens.

From here, the paths split. Follow Path A to generate a new wallpaper from a text prompt, or Path B to extend an existing photo.

Path A: how to create custom iPhone wallpapers in iOS 27 with Image Playground

1. Look for an Image Playground option in the wallpaper picker. Based on MacRumors' reporting last month, this option surfaces during the wallpaper selection flow. The exact label isn't confirmed; look for an AI generation or Image Playground entry alongside Photos, Colors, and other existing categories in the top bar.

2. Type a description of the wallpaper you want. Include subject, mood, color palette, and stylistic direction. The more specific the description, the more useful the output tends to be in practice.

3. Watch for a generating state. If Apple follows the same pattern as other AI wallpaper features, you'll likely see a brief processing step before the result appears. The existing Spatial Scene feature, for reference, shows a "Generating Spatial Scene" message while it works, per Apple Support.

4. Review the result. If it fits what you had in mind, proceed. If not, refine the prompt and try again. Specific retry controls and prompt-editing options haven't been confirmed in available pre-release materials.

5. Tap Add, then choose how to apply it. Select Set as Wallpaper Pair to apply to both Lock Screen and Home Screen, or Customize Home Screen to configure them separately, following the existing Apple Support flow.

What's confirmed: Image Playground generates wallpapers from text descriptions and sets them as Lock Screen wallpaper (MacRumors, this week); Apple's WWDC session confirms photorealistic image output for wallpapers. The final Add/Set as Wallpaper Pair step follows established Apple Support documentation.

Not yet confirmed: The exact menu label for Image Playground in the picker; how many results generate per prompt; whether style controls or prompt editing are available after the first result.

Path B: extend an existing photo to fill the Lock Screen

1. Tap Photos in the wallpaper picker. This follows the existing path documented by Apple Support.

2. Select the photo you want to use. Photos with natural or simple backgrounds will give the extension model the most to work with: sky, water, landscape, soft gradients. Tight portraits or images with complex detail at the edges are harder for the AI to extend convincingly.

3. Look for a wallpaper extension option once the photo is selected. The exact label isn't confirmed, but based on how similar controls work in the current wallpaper flow, it's reasonable to expect it near where the Spatial Scene toggle appears during Lock Screen customization. The Spatial Scene option appears as an on/off control during that step, according to Apple Support.

4. Enable the extension and preview the result. The AI fills in the borders to create a full-bleed Lock Screen. Check the edges before committing; that's where quality variation will show up most clearly.

5. Tap Add and set as wallpaper, using the same confirmation step as Path A.

What's confirmed: The feature uses Apple Intelligence to expand photos beyond their original boundaries for a full-screen Lock Screen presentation (MacRumors, this week). Entry via Photos in the picker and the final Add step both follow existing Apple Support documentation.

Not yet confirmed: The exact toggle or button label; whether extension applies to the Home Screen or the Lock Screen only; whether you can regenerate or adjust the expansion after previewing.

Before iOS 27 ships: three things worth knowing

The UI paths above are reconstructed, not confirmed. This guide is built from WWDC presentations, Apple developer materials, and pre-release reporting, not a shipping build. Apple's developer session confirms both features exist; the exact interface to reach them may look different in the final release. When iOS 27 ships, the specific labels and step sequences will be updated here.

Quality will vary, especially at first. Apple may be testing more lifelike image models for wallpaper generation, per earlier MacRumors reporting last month, but there are no hands-on reviews or comparisons yet. Photo extension quality depends heavily on the source image. A wide-open sky extends well; a busy background with detailed edges is a harder problem.

Eligibility requirements apply to both tools. If Apple Intelligence isn't active on your device in a supported language, neither tool will appear. The time to check is now, before iOS 27 ships, not the morning you try to use it.

What to do now

Both wallpaper tools land this fall alongside the broader iOS 27 and Apple Intelligence rollout, confirmed by Apple at WWDC this week. The practical preparation is straightforward: verify that your device supports Apple Intelligence and that your language is configured correctly in Settings > Apple Intelligence & Siri.

Once iOS 27 ships, the step sequences above will be updated with confirmed labels and, where available, screenshots. The two tools themselves are confirmed; everything about exactly where the buttons live is still subject to change.
