Image Extender for Phone Wallpapers
Someone with a square or landscape photo who wants a true full-screen phone wallpaper instead of a cropped or zoomed-in version.
A square or landscape photo doesn't fill a phone screen without stretching or leaving black bars. The extender takes that photo and extends the background above and below the subject so it fills a 9:16 phone screen without cropping the subject out.

About extend photos into phone wallpapers
Is an image extender reliable enough for phone wallpapers?
For photos with continuous backgrounds (sky, wall, open water, plain floor), the result is close to indistinguishable from a wider original shot. For cluttered scenes with objects cut off at the edge, add the built-in direction to steer the model.
Does this replace a dedicated upscaler?
No. This tool extends the canvas to a target aspect ratio at a standard output resolution — it does not enlarge an already high-resolution photo. If you need a much larger, print-DPI-grade file, run the result through a dedicated upscaler afterward; see our honest-limits article for where that line is.
Will the subject itself change?
No — the original subject's pixels are preserved. Only the new pixels around it are AI-generated, so faces, text, and fine detail stay accurate for the wallpaper or print.
