About App Icon Generator
App Icon Generator is an online tool designed for developers to quickly generate all required icon sizes for iOS, Android, and Web platforms. It supports favicon.ico, apple-touch-icon, and Android mipmap formats, and can automatically center-crop a single 1024x1024 PNG image and export it into thirteen common sizes. Whether you are an independent developer or working in a team, App Icon Generator can significantly improve your app submission efficiency and eliminate the tedious work of manually resizing icons.
How to Use App Icon Generator
Using App Icon Generator is very simple: first, click or drag and drop to upload an image; a 1024x1024 PNG file is recommended, and a transparent background works best. Next, the tool automatically center-crops the image and generates all icon sizes from 16x16 to 512x512, and you can preview the result of each size. Finally, you can download a single size individually, or click "Download All" to get every icon at once. The entire process runs locally in your browser, requires no registration, and never uploads any data. If you need a complete set of assets that meets App icon guidelines, App Icon Generator is an ideal choice.
Related Knowledge About App Icon Generator and Multi-Size Icons
In mobile development, different platforms have strict requirements for icon sizes. iOS development requires AppIcon to include multiple sizes from 20x20 to 1024x1024, divided into @2x and @3x scales; Android requires five densities in the mipmap directory—mdpi, hdpi, xhdpi, xxhdpi, and xxxhdpi—as well as a 512x512 icon for the Play Store. For websites, favicon.ico (containing 16x16 and 32x32) and apple-touch-icon (180x180) are usually needed. App Icon Generator covers these common sizes and exports everything uniformly in PNG format, making it easy to use directly in Xcode, Android Studio, or website deployment. In addition, favicon.ico has high compatibility requirements, while apple-touch-icon affects how the icon appears after being added to the home screen on iOS devices, so batch generation with App Icon Generator can effectively prevent omissions.
