DrAppIcon — Create Mobile App Icons

DrAppIcon turns a single image into a complete app icon set for iOS and Android: the iOS AppIcon.appiconset with Contents.json, Android legacy and round launcher icons, adaptive icon foreground, background and monochrome layers, and the 512 px Play Store icon. It is free, needs no account, and generates everything locally in your browser — your artwork is never uploaded. JavaScript is required to use the generator.
