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?
Treat each result as a draft to review. Photos with continuous backgrounds (sky, wall, open water, plain floor) give the model the easiest edges to continue; still compare the result with the source before publishing. 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?
It can. The tool is built to add background around the subject, not to redraw it, but exact preservation is not guaranteed. Compare faces, text, and fine detail with the source before using the result as a wallpaper or print.
