Keep the whole photo
Scales until every edge fits inside the phone. Any extra screen area uses your chosen solid color. Best for posters, text, artwork, and group photos.
Your photo. Your screen. No stretch.
Turn any photo into a wallpaper that actually fits. Choose your phone, keep the whole image or control the crop, preview the clock and icons, then download the exact pixels—free and private.
Free local editor
Your image stays on this device. The file opens and exports with browser Canvas APIs; this site has no image-upload endpoint.
Guides are a composition aid and are not included in the downloaded image. Actual phone UI varies by model, launcher, widgets, and settings.
Choose an image to begin. Nothing is uploaded.
Two minutes, three decisions
A resizer changes pixel dimensions. A wallpaper editor also resolves the aspect-ratio mismatch and shows where the phone UI will sit.
Useful starting points
Use the display resolution when you know the model. The safest exact method is to inspect a screenshot from the same phone and enter its pixel width and height.
| Preset | Pixels (portrait) | Aspect | Best use |
|---|---|---|---|
| iPhone 16 Pro | 1206 × 2622 |
≈ 19.6:9 | Exact preset for the 16 Pro display |
| iPhone 16 Pro Max | 1320 × 2868 |
≈ 19.6:9 | Large modern iPhone lock screens |
| Pixel 9 | 1080 × 2424 |
20.2:9 | Pixel 9 screenshot-sized export |
| Galaxy S24 / S25 | 1080 × 2340 |
19.5:9 | Current standard Galaxy S models |
| Galaxy S24 / S25 Ultra | 1440 × 3120 |
19.5:9 | QHD+ Ultra display output |
| Generic Android 20:9 | 1080 × 2400 |
20:9 | A practical fallback when the model is unknown |
A screen resolution is a preset, not a visibility guarantee. iOS and Android may zoom, scroll, apply motion effects, or place widgets over the bitmap. Keep faces and text inside the visible subject-safe guide.
Fit, fill, or blur
Stretching changes the subject’s shape. This editor always preserves the original aspect ratio and lets you choose what happens to the remaining space.
Scales until every edge fits inside the phone. Any extra screen area uses your chosen solid color. Best for posters, text, artwork, and group photos.
Scales until the phone is covered, then crops the overflow. Drag to keep the face, pet, or horizon where you want it. Best for full-bleed photography.
Shows the full photo over a softened copy that fills the background. Best when you want no hard border and no lost subject.
Straight answers
The right answer depends on your source ratio, phone pixels, and whether seeing the whole photo matters more than filling every edge.
Use your display resolution or, more reliably, the pixel dimensions of a screenshot made on that phone. Select a preset or enter the screenshot width and height under Exact output pixels.
Choose Fit for a solid background or Blur fill for a photo-based background. Both keep the entire source visible. Fill intentionally crops the overflow.
No. Every mode uses one uniform scale for width and height. The status panel tells you whether the result crops, pads, or matches the target ratio.
No image leaves your browser. JavaScript reads the selected file into memory, Canvas composes the result, and your browser creates the download. Refreshing the page clears that working state.
Some launchers add zoom, motion, scrolling, or parallax after you choose the file. Pinch outward in the phone’s wallpaper setup screen where supported, disable motion effects, or keep critical content farther from the edges.
Choose JPEG for photographs and smaller files, PNG for sharp text or graphics, and WebP when your phone and workflow accept it. The selected format does not change the output pixels.
Yes. Fit and Blur fill preserve the wide frame. Fill creates a narrow portrait crop; drag left or right to choose which part remains visible.
No. They are preview overlays only. They help you place the subject, but the exported wallpaper contains only your composition.
Evidence, not folklore
Presets come from manufacturer display specifications. The composition uses standard browser file and Canvas APIs.
Apple’s comparison page, Google’s Pixel hardware table, and Samsung’s device specifications provide the display-resolution starting points.
Canvas 2D draws each source with one scale factor. Fit uses the smaller width/height ratio; Fill uses the larger one.
The File API exposes only the file you choose. Canvas exports a new Blob inside the browser, which becomes the download.
