What works
- Keep the top third calm on phones; the clock and widgets sit there.
- Ask for "no text" and avoid busy patterns behind app icons.
- Generate, then upscale 2×, then crop to your exact screen with the resizer.
- Dark wallpapers save battery on OLED phones.
Questions people ask
What size should a phone wallpaper be?
Use your screen's native resolution: roughly 1179 × 2556 to 1320 × 2868 for recent iPhones and about 1080 × 2400 for many Android phones. Upscale the portrait output 2× and crop it to that size with the image resizer.
Can I make a 4K desktop wallpaper?
Generate landscape (1536 × 1024), upscale 3× with the image upscaler and crop to 3840 × 2160. Soft scenes upscale best; fine textures can look smoothed.
Is it free?
Yes, about 8 wallpapers an hour, no account, no watermark.
