1. Write the scene
Describe the subject, colors, texture and lighting. Say where the main subject should sit and which areas should remain uncluttered. For a new wallpaper, start with text and leave reference uploads empty.
AI wallpaper generator
Your words. A personal wallpaper.
An AI wallpaper generator turns a text description into a background image. Use Nano Banana 2 in the existing image generator for 17 credits at 1K, with 9:16 portrait or 16:9 landscape options. Describe a subject, palette and empty space for icons; select the ratio manually and check how your device crops the result. This guide provides prompts, not downloadable wallpaper samples.
Use descriptions and reference material you have the right to use. This independent website is not affiliated with or endorsed by Google. Generated artwork is not an official branded wallpaper, and device cropping can change the visible composition.
Start from a written description; no reference photo required

How to generate a wallpaper
From description to screen background
Choose a subject and color palette, then plan quiet areas around the clock, widgets or desktop icons. A ratio is a composition choice, not a promise of an exact device fit.
2. Select the model and ratio
Open the image generator and manually select Nano Banana 2. Choose 9:16 for a portrait starting point or 16:9 for landscape. Paste a prompt below; the link does not select a model, ratio or prompt for you.
3. Review the quote and crop
Sign in and review the displayed quote before generating. Nano Banana 2 text-to-image costs 17 credits at 1K or 40 credits at 4K. Download a result you like and preview it on your device; adjust the crop if the clock or icons cover the subject.
Wallpaper prompt examples
Design around the space your screen needs
Copy a prompt into the existing generator and set the ratio separately. These are untested prompt ideas, not example model outputs or guarantees of exact composition.
Quiet phone landscape
Create a portrait wallpaper of misty mountains at dawn, muted blue and warm peach palette, soft atmospheric light, fine natural texture. Put the mountain ridges in the lower part of the frame and leave a calm open sky above for a lock-screen clock. No lettering, logos or border.
Minimal desktop gradient
Create a landscape desktop wallpaper with flowing matte shapes and a charcoal-to-deep-teal gradient. Place the visual detail toward the right and keep the left side quiet for desktop icons. Soft light, restrained contrast, no lettering, logos or border.
Botanical background
Create a wallpaper of delicate fern silhouettes against a warm cream background, subtle paper texture and soft indirect light. Keep the central area uncluttered and place foliage near the edges. No lettering, logos or border. Compose for the aspect ratio selected in the tool.
Screen planning
Match the composition to everyday use
Different screens and launcher settings crop images differently. Preview the actual lock screen, home screen or desktop before deciding whether a wallpaper works.
Phone and lock screen
Use 9:16 as a portrait starting point. Leave room around the clock and widgets, keep important detail away from the edges and check both lock-screen and home-screen crops.
Desktop and laptop
Use 16:9 as a landscape starting point. Keep the area behind icons simple. A wider monitor or a multi-monitor layout can need another supported ratio or manual cropping.
Resolution and visual checks
Choose a resolution offered by the selected model and check the quote. Inspect gradients, fine patterns and unwanted text at the size you plan to use. Resolution labels do not guarantee an exact match to your screen dimensions.

FAQ
AI wallpaper generator questions
Can I generate a wallpaper without uploading a photo?
Yes. Select Nano Banana 2, leave reference uploads empty and describe the wallpaper in the existing image generator. Choose your aspect ratio before submitting.
Which ratios should I use for phone and desktop wallpaper?
Start with 9:16 for portrait phone backgrounds or 16:9 for landscape desktop backgrounds. Check your device crop and leave space for clocks, widgets and icons; these ratios do not fit every screen exactly.
Is the wallpaper generator free?
No. This Nano Banana 2 text-to-image workflow uses 17 credits at 1K or 40 credits at 4K. Sign in and check your balance and displayed quote before submitting.
Does the link automatically set the wallpaper prompt?
No. The generator link does not prefill a prompt, select the model or ratio, or submit a job. Paste your instruction and choose the settings manually.
Will the image fit my screen without cropping?
No. Screen dimensions and wallpaper settings can crop or scale the image. Preview it on your device and adjust the framing before setting it as a background.
Can I use brand logos or another artist’s images?
Yes, only with the necessary rights or permission and in accordance with the service terms. Use original descriptions when you do not have permission to use protected material; generated output is not an official branded wallpaper.
