Set the wrong-sized image as an iPhone wallpaper and iOS stretches, zooms or crops it in ways you didn’t choose. This tool gives you control: pick your exact iPhone model, drop in any photo, and it produces a wallpaper at the precise pixel resolution that model’s screen expects — filling the frame cleanly with no distortion.
It works entirely in your browser, so your photo is never uploaded. Choose from every recent iPhone size, preview the crop, and download a ready-to-use wallpaper for your Lock Screen or Home Screen in one tap.

Frequently asked questions
What is the correct iPhone wallpaper size?
It depends on your model. For example, iPhone 15 Pro Max and 14 Pro Max use 1290 × 2796 pixels, iPhone 15 and 14 use 1179 × 2556, and older models differ. This tool picks the exact resolution for you once you select your model, so you never have to memorise the numbers.
Why does my wallpaper look zoomed or blurry on iPhone?
iOS zooms wallpapers that don’t match the screen resolution, and it enlarges images that are too small, which looks blurry. Resizing your photo to the exact pixel dimensions of your model — as this tool does — prevents both problems.
Is my photo uploaded when I resize it?
No. All the cropping and resizing happens locally in your browser using a canvas. Your photo never leaves your device and isn’t stored anywhere.
Can I use it for the Lock Screen and Home Screen?
Yes. The output matches your full screen resolution, which works for both the Lock Screen and Home Screen. iOS may apply a slight blur to the Home Screen for legibility, but the fit will be correct.
