Easily generate image assets for Cordova-based projects

This handy tool generates icons and splash screens for Cordova and development tools based on Cordova, like VoltBuilder, Ionic, Monaca etc.

If you use VoltBuilder, it's also possible to have images auto-generated as part of building an application. See Generating Icons and Splash Screens.

Upload a preferably square app icon and an optional splash screen background in a high resolution bit image format, but preferably PNG, each less than 16 megapixels. Both images can have transparency/alpha. See below for a list of supported formats.

Images are generated for iOS (legacy) , iOS (storyboard) , Android  and Windows , in portrait and optionally landscape , in folders for access from config.xml.

Choose an icon to upload:

Choose an optional splash screen background to upload:

...or choose a background color: (#rrggbbaa, #rgb, rgba(red, green, blue), hsl(hue°, saturation%, lightness%), cmyk(C%, M%, Y%, K%), HTML color name)

Fit type: FitStretchFill(how to fit the splash screen; Fit and Fill retain aspect ratio)
App icon overlay: (the app icon will overlay the splash screen)
App icon ratio: % (sets the coverage ratio, retaining aspect ratio)

Recommendations

• Read here about what icons and splash/launch screens are needed by Cordova projects, that this tool adhers to:
  • Customize Icons - Apache Cordova
  • Splashscreen - Apache Cordova
• The uploaded images should be 1 megapixels or more for high enough quality, but less than 16 megapixels (larger will generate an error).
• Avoid photos or images with gradients if possible. They slow down conversions and make the app very big.
• If you get a timeout error, try to convert for one platform at a time.
• Images for respective store are stored under the folder archive. Optionally move the folder outside of the project.
• Here's a config.xml snippet showing the use of the created images.

Supported image formats

These are the image formats supported by ImageMagick. There's still no guarantee all work as expected. Notably there's an issue with SVG.
