Will the wallpaper fit my phone exactly?

Use the 9:16 phone preset and the wallpaper is generated to a vertical ratio that fits most modern phones. You can crop slightly when setting it if your model has an unusual screen.

Can I make a separate lock screen and home screen?

Yes. Generate two wallpapers with different prompts, or keep the same scene and ask for a cleaner version with more empty space for your lock screen clock.

It is free to start and the free tier needs no login. You can generate phone wallpapers without creating an account.

1
Describe your wallpaper
Write a short prompt with a subject, mood, and colors. For example: a calm purple night sky over rolling hills, soft gradient, minimal stars. Specific details give a cleaner result than one-word prompts.
2
Pick the 9:16 phone preset
Choose the 9:16 portrait ratio so the wallpaper fits a phone screen edge to edge. This keeps the focal point centered and avoids the awkward cropping you get from a landscape image.
3
Generate and refine
Generate, then tweak the prompt if you want a different palette or composition. Try adjusting one thing at a time, like swapping purple for teal, to steer the look.
4
Download in 4K
Export the wallpaper up to 4K so it stays crisp on high-density phone displays, then set it as your home or lock screen.

Sized for phones

The 9:16 preset matches modern phone aspect ratios, so the wallpaper fills the screen without stretching or losing the main subject behind icons.

Made from your words

Describe a specific scene, color, or vibe and get a unique background instead of a stock image shared by thousands of other people.

Crisp on retina displays

4K exports keep edges and gradients clean on high-resolution phone screens, where lower-res images often look soft.

No app, no login to start

It runs in your phone's browser. There is nothing to install and the free tier does not require an account.
