Who knows how to change the picture to the size of a mobile phone screen? The wallpaper I downloaded is not as big as my mobile phone.
Download a picture browser, and I will introduce the method of using Mito Xiu Xiu. Open Meitu Xiu Xiu, edit the picture, select the size, and then modify the size in the dialog box that appears, just change it to the size of your mobile phone. General mobile phone screen size is 240 ⅹ 320,600 ⅹ 800,768 ⅹ1024 and so on.
