Frequently Asked Questions

What is a web app manifest?

A web app manifest is a JSON file that provides information about a web application, such as its name, icons, and theme colors. It enables the app to be installed on a device's home screen and behave like a native app.

Where should I place the manifest.json file?

Place the manifest.json file in the root directory of your website (e.g., https://example.com/manifest.json) and reference it in your HTML head with: <link rel="manifest" href="/manifest.json" />

What icon sizes should I include?

At minimum, include 192x192 and 512x512 icons. The 192x192 icon is used for the home screen icon, and 512x512 is used for the splash screen. You can also include other sizes for better compatibility.

What is the difference between theme color and background color?

Theme color affects the browser's address bar and UI elements. Background color is shown as the splash screen background while your app loads when launched from the home screen.
