Convert photo to full screen wallpaper
The photo ratio does not match the screen ratio. If it is set as wallpaper, key parts will be cut off or black borders will be left on both sides. This tool has built-in precise device resolutions - iPhone generations, mainstream Android models, 4K and 2K desktops, hairtail screens, dual screens, iPads, Apple Watches - select the device and automatically crop it to fit.
Choose between the two modes according to the situation: If the subject is in the center and there is no important content around it, use "Fill the screen" to cut off the edges and fill it completely; if it is a group photo or landscape that you are reluctant to crop, use "Keep the whole picture" to put the complete picture in and use the same picture to blur and enlarge the blank space, at the expense of a blurred border.
There is another step that has nothing to do with tools but is easier to overturn: the phone lock screen has the time and date at the top, flashlight and camera buttons at the bottom, and a row of icons on the desktop. It is the most common situation that the human face is just covered by time. For vertical wallpapers, it is usually more stable to move the subject slightly downward.
A batch of photos can be adapted to the same device at one time and packaged in ZIP.
