How to Use the OpenArt AI Wallpaper Generator

Step 1: Describe Your Wallpaper

Open Create Image, choose a model such as GPT Image 2 or Nano Banana Pro, and describe the subject, palette, lighting, and mood. Starting from a photo instead? Add it under "Add visual references" in the same step.

Step 2: Set Your Aspect Ratio

Choose 9:16 for phone, 16:9 for desktop, 21:9 for ultrawide, or square, pick a quality level, and hit Generate.

Step 3: Upscale and Download

Run the result through the 4K Image Upscaler, then export it and set it as your wallpaper.

Create AI Wallpapers for Every Screen and Style

From a phone lock screen to a matched pair across every device you own, OpenArt covers the wallpaper scenarios that actually show up in consumer searches.

Phone Lock Screens

Phone Lock Screens

Generate image at 9:16 and keep the main subject clear of the clock, notification, and app-icon bands so the composition still reads once your interface sits on top of it. Nano Banana Pro and GPT Image 2 both hold up well at this ratio for portrait-oriented scenes.

Ultrawide and Desktop Monitors

Ultrawide and Desktop Monitors

A 21:9 canvas exposes the weakest point of most stock photography: it usually wasn't shot that wide. Generating natively in 21:9 with Seedream 5.0 Pro gives a panoramic landscape or an abstract composition room to fill the full display.

Travel Photos Turned Into Nature Wallpapers

Travel Photos Turned Into Nature Wallpapers

Upload that grassland or mountain shot from your camera roll and restyle it into a polished nature wallpaper. OpenArt keeps your original composition and light, then renders it with painterly or cinematic detail, sized for phone, desktop, or ultrawide.

Specific Aesthetics a Wallpaper App Doesn't Carry

Specific Aesthetics a Wallpaper App Doesn't Carry

Anime, retro synthwave, minimalist abstract, whatever a fixed preset library doesn't stock, describe it directly with FLUX.2 Pro or Nano Banana Pro instead of digging through someone else's filter list.

4K Upscaling Wallpaper

4K Upscaling Wallpaper

Run any wallpaper through the 4K Image Upscaler before it goes live. A resolution that looks fine in a preview thumbnail often looks soft once it's stretched behind a home screen full of icons.

Frequently Asked Questions

Phone (9:16), desktop (16:9), ultrawide (21:9), and square, so nothing looks stretched or cropped on your actual screen.
Yes. Specify the aspect ratio or resolution you need, from ultrawide desktop monitors to vertical phone screens. The AI generates the image to fit.
Generate at 16:9 for a standard desktop or 21:9 for ultrawide, and favor panoramic or abstract compositions over a single centered subject.
Be specific about mood, color palette, and composition. 'Dark blue ocean waves under a starry sky, wide angle' works better than 'ocean'. Reference art styles or lighting conditions to refine results.
AI wallpaper 4k generator is a tool that creates a background image from a text prompt or an uploaded photo instead of pulling one from a stock library. You describe what you want, or upload a photo to restyle, and it builds a new image sized for your screen.
Yes. Upload it as a reference image with the AI Image to Image Generator, describe the restyle you want, and set the aspect ratio for your screen.
Photorealistic landscapes, anime art, abstract patterns, fantasy scenes, minimalist designs, retro aesthetics. Any style you can describe in a prompt.
