iPhone Duo wallpaper generator: free downloads in four steps
How the built-in iPhone Duo wallpaper generator works — pick a preset or your own accent colour, drag the light, tune texture and angle, then export a 2670 × 1878 JPG. Free downloads, no watermark, nothing uploaded.
iPhone Duo wallpaper generator is the free wallpaper tool built into this site: pick one accent colour, the light and dark ends are derived automatically, and it renders a 2670 × 1878 image at the iPhone Duo inner display's native resolution. Hit "Download wallpaper" and the file lands in your downloads. Everything renders in the browser — nothing is uploaded, and there is no watermark or sign-in.
What you can make
- 100 presets — seven colour families × six saturation steps, plus eight steps each for black and white, split into light and dark rows;
- Any accent colour — pick a value with the colour input and both endpoints are derived in HSL, no manual three-stop ramp;
- Draggable light — click the preview and the highlight moves there; intensity, light size and gradient angle each have their own slider;
- Six textures — grain, rays, Fibonacci spiral, sound wave, dots and concentric rings, with independent strength;
- Waves — bends the gradient's contour lines slightly, so the edge reads like real light.
Four steps
- Pick a colour. Choose a preset under "Accent", or set your own. The swatch strip below runs left to right in gradient order and recalculates when the accent changes.
- Move the light. Click the preview to place the highlight, then set contrast with intensity and light size.
- Add texture (optional). Default is "None"; a very faint white line layer reads like paper or film, and 20% strength is as far as it usually needs to go.
- Download. "Download wallpaper" saves
duo-wallpaper-<accent>-2670x1878.jpg. The preview overlay shows that same full-resolution image, not an upscaled thumbnail.
About the size
Export is fixed at 2670 × 1878 — the inner display's native landscape resolution — so iOS will not upscale it on the lock screen or home screen. For a portrait result, rotate the image 90° and crop in Settings. The "Outer / Inner" switch on the canvas is preview only and does not change the export size.
After the download
- iPhone Duo wallpaper download: save to Photos, then Settings → Wallpaper → Add New Wallpaper and pick the file;
- Phone wallpaper download works the same on other foldables and slab phones — the system crops to fit;
- For social covers and article headers, 2670 × 1878 fills a 16:9 area with room to spare.
FAQ
- Is it free? Yes. Free wallpaper downloads, no account, no watermark.
- Are my files uploaded? No. Rendering happens in local WebGL with no upload requests.
- It says WebGL is unsupported. Try a current Chrome, Edge or Safari; some stripped-down browsers ship with hardware acceleration off, and enabling it is enough.
- Can I use the result commercially? Use it yourself or inside your own content; repackaging generated wallpapers as an asset pack is not the intent.
