Is the AI wallpaper generator free?

Plans start at $19 a month. A 4K phone or desktop wallpaper from a prompt costs 1 credit at low quality and 5 at high, so the Creator plan's 500 credits make up to 500 of them, about $0.04 each. Adding your own photo as a reference adds 3 credits.

What size do the wallpapers come out?

At 4K, a phone wallpaper is 2160 × 3840 pixels and a desktop one is 3840 × 2160, the size of a 4K monitor. Ultrawide is 3840 × 1648 and a 3:2 laptop wallpaper is 3520 × 2352. The table above lists every shape at 2K and 4K.

Will it fit my iPhone or Pixel?

Yes, with a little off the sides. An iPhone 18 Pro screen is 1206 × 2622 pixels and a Pixel 11 is 1080 × 2424. A 9:16 wallpaper at 4K is 2160 × 3840, more pixels than either, but both screens are taller than 9:16, so the lock screen trims about 9 to 10% from each side. Keep the subject away from the edges. For a phone-tall shape, Grok Imagine 2.0 offers 9:19.5 and 9:20, and Fill with AI in the image editor's Crop tool extends a picture to 9:21.

How do I keep the clock and icons readable?

Ask for a calm, even top third and put the subject low in the frame. On a desktop, keep one side quiet for your icons. Then check the lock screen before you keep it.

Can I make a matching phone and desktop pair?

Yes. Make the desktop wallpaper first. Then add it as a reference and ask for a vertical version of the same scene, with the same light and colors.

Can I put a quote or my name on it?

Yes. Write the exact words in quotes and say where they go. GPT Image 2.5 Sunburst, the default model, is built for text in images. Keep it short and check the spelling before you set it.

Can I make a wallpaper from my own photo?

Yes. Add your photo as a reference and describe what to make of it, like a paper-cut illustration of your dog on a yellow background.

Can it make a live or animated wallpaper?

It can turn a wallpaper into a short video. In Video generation, use Seedance 2.5 with the wallpaper as both the start and the end frame, and the clip loops back to where it began. Whether your phone can use a video as its wallpaper depends on the phone.

Can I use the wallpaper anywhere?

Yes. Every paid plan includes commercial use and exports without a watermark.

Will the clock cover it?Try it on your screen first

The same lighthouse, asked for in two places. Your lock screen's clock sits in the top third of the screen, so a subject up there ends up behind it.

A white lighthouse on a tall sea stack at dusk, placed at the very top of the frame — Lighthouse at the top
The clock lands on the lighthouse.
"…so the lighthouse sits near the very top of the frame."

A white lighthouse on a low rock at dusk, with an empty violet sky filling the top of the frame — Lighthouse kept low
Clear sky under the clock.
"…on a low rock in the lower third of the frame. Keep the top third calm and even, with nothing in it but sky, so the clock stays readable."

Smooth sand dunes at dusk rising toward the right, with a quiet peach and lavender sky on the left — On a desktop, keep one side quiet
The prompt asked for an even left third, so the icons sit on plain sand and sky. The dunes rise on the right, where nothing covers them.
The sentence that did it
"Keep the left third quiet and even, only soft sand and sky, so desktop icons stay readable."

Current iPhones are about 9:19.5 and Pixel 11 phones 9:20, both taller than a 9:16 wallpaper. The lock screen fills the height and cuts about 9 to 10% from each side, so keep the subject away from the edges.

How to make an AI wallpaperDescribe it, shape it, check the clock

1
Describe the scene and the empty space
Name the place, the light and the colors. Then say where nothing should go: a calm top third on a phone, one quiet side on a desktop.
2
Pick the shape and 4K
9:16 for a phone, 16:9 for a monitor, 21:9 for an ultrawide. Set the resolution to 4K.
3
Set it and check the clock
Download it, set it, and look at the lock screen. If the clock lands on the subject, ask for the subject lower and run it again.

The shape to pick for your screen

Every pick has at least as many pixels as the screen, so it is scaled down, never up. Screen sizes are from Apple's, Google's and Microsoft's spec pages, November 2026.

Matching phone and desktopOne scene, two screens

Make the desktop wallpaper first. Then add it as a reference and ask for the phone version, so the light and colors carry over.

The same dunes at dusk in a tall frame, the crests in the lower half under a lavender sky

1 · Desktop, 16:9 at 4K
A wide view of smooth sand dunes at dusk, long violet shadows across the sand, a pale peach to lavender gradient sky, the dunes rising toward the right side of the frame. Keep the left third quiet and even, only soft sand and sky, so desktop icons stay readable. Desktop wallpaper, photographic, no people, no footprints.
2 · Phone, 9:16 at 4K, desktop added as a reference
Make a vertical phone wallpaper of the same dunes, with the same light, colors and violet shadows. Put the dune crests in the lower half. Keep the top third calm and even, with nothing in it but sky, so the clock stays readable.

Colors, quotes, names, your photoNot every wallpaper is a view

Gradient
No subject at all. A gradient never fights the clock or your icons.
A soft gradient from deep teal at the bottom to pale mint at the top, with a faint film grain. No shapes, no objects, no text. Phone wallpaper.
A quote
Write the words in quotes and say where they go. Read every letter before you set it.
Phone wallpaper of cream paper with a faint linen texture. In the lower half, centered, in a simple serif typeface, write exactly: "Slow is smooth. Smooth is fast." on two lines. No other text. Nothing in the top third but the paper.
A name
A name or an initial works the same way. Short words come out cleanest.
Phone wallpaper with a dusty rose background. In the lower half, a large letter M drawn in thin gold line art, with the name "Maya" in small, widely spaced capitals under it. No other text. Keep the top third calm and even, with nothing in it but the background color.
Reference photo
From your photo
Add your own photo as a reference and say what to make of it.
Make a phone wallpaper of this dog as a flat paper-cut illustration, lying at the bottom of the frame on a warm yellow background. Keep the same coat color and the same pose. Leave the top half empty, only the yellow background.

Live wallpaperMake it move

Turn a wallpaper into a short clip. Use the same picture as the start and the end frame, so the clip begins and ends on your wallpaper and can play on repeat. Watch the seam before you use it: motion in between can still jump. Whether your phone plays a video as its wallpaper depends on the phone.

Three orange and white koi seen from above in dark green water, with lily pads at the edges — Start frame

Prompt for the loop

The three koi glide in one slow loop across the dark green pond and swim back to the exact places they started from, sunlight ripples shimmering over the stones and the lily pads bobbing gently. Overhead shot, the camera does not move. No narration.
