You can use Image Resizer to create all the app icons you need for your iPhone/iPad, Mac OS X and Android app.
iPhone/iPad and Mac OS X icons are created as a preconfigured Xcode Asset Catalog that you can drag into your project folder. An icon.icns file is also created for Mac OS X icons but it is recommended to use the Asset Catalog instead.
Android icons are placed in subfolders based on their screen density, e.g. drawable-xxhdpi.
Create one large format icon (at least 1024pt), drag it into the Source Image placeholder then save the app icon to create the following size icons;
