Usage

The command below will generate various appropriately sized icons in the current working directory, by resizing the input file (example.png). For best results, use a high quality square image of at least 512x512 pixels. Finally, it will also generate a manifest.webmanifest file.

npx webmanifest-generator generate example.png --lang en --dir ltr --name my-app-name-here --description Some description --short-name my-app --scope / --id / --start-url / --display standalone --orientation any --theme-color ffffff --background-color ffffff

The command arguments should match the expected member values of the web application manifest. All options are optional, however, an input image file is required. Reference here
