Step 1
Pick a preset
In /app/image, choose Wallpaper (16:9 · 2K) for desktop or Story / Reel (9:16) for phone.

Wallpapers work best with a clear subject off-centre and calm space around it — landscapes, skies, cities, fantasy scenes.
Step 3

Pick Seedream 5.0 Lite and a 4K size (2304×4096 phone or 4096×2304 desktop) — or upscale any image up to 4K.

FAQ
AI wallpaper generator questions
What is an AI wallpaper generator?
A tool that makes a phone or desktop wallpaper from a text description, at the right shape and resolution for your screen. Good wallpapers have one clear subject placed off-centre, calm areas where icons and the clock go, and no text. On Kenerate the Wallpaper and Story / Reel presets set the shape for you.
Link to this answerCan I make 4K wallpapers?
Yes. Seedream 5.0 Lite has 4K sizes for phone (2304×4096) and desktop (4096×2304), so the image matches the screen without cropping. GPT Image 2 also renders up to 4K. If you already have an image you love, the Image Upscaler enlarges it up to 4K instead of generating again.
Link to this answerIs it free?
Yes, to start. A free account gets starter credits on sign-up to test, and Flux 2 Dev is on the free plan for drafts up to 2048 px. 4K models such as Seedream 5.0 Lite unlock with a one-time credit pack, and credits never expire. The 13 wallpapers on this page are free to download.
Link to this answerWhat size should a phone wallpaper be?
A tall 9:16 image at 1080×1920 or higher works on most phones, which use a 9:16 or taller screen. 1440×2560 is the 2K option, and 2304×4096 on Seedream 5.0 Lite covers high-resolution screens. Generate at 9:16 from the start with the Story / Reel preset, because a 9:16 crop from a square image loses most of the scene.
Link to this answerWhat size is a desktop wallpaper?
16:9 fits most monitors: 1920×1080 for Full HD, 2560×1440 for QHD and 3840×2160 or 4096×2304 for 4K. The Wallpaper preset makes 16:9 at 2K, and Seedream 5.0 Lite has a 4096×2304 size for 4K monitors and TVs. Tablets use 4:3 or 3:4 instead, with 2K and 4K sizes in the generator.
Link to this answerDoes it add a watermark?
No. Images download without a watermark, on starter credits and paid credits alike, so you can set them straight as a lock screen or desktop background. The 13 free wallpapers on this page download the same way — tap one to open it full size and save it.

AI wallpapers, explained
What makes a good wallpaper, getting the shape right, and when to upscale.
On this page
What makes a good wallpaper
A wallpaper sits behind icons, widgets and a clock, so it needs different things from a poster:
- One clear subject, placed off-centre or low in the frame.
- Calm areas where icons and the clock go — sky, water, soft shadow.
- No text in the image; your phone adds its own.
- Mood through light: dawn, golden hour, neon, moonlight.
Getting the shape right
Generate at the shape you'll use. A 9:16 image cropped from a square loses most of the scene; a 16:9 wallpaper made at 16:9 keeps it. The presets set the shape for you, and the 4K sizes on Seedream 5.0 Lite match phones and monitors directly.
Resolution and upscaling
Most phones look sharp at 1080×1920; high-end phones and 4K monitors benefit from 4K. If you already have an image you love, the Image Upscaler enlarges it up to 4K instead of generating again.
