Favicon vs App Icon
Differences, use cases, and when to use each
Favicons are small browser tab icons (16x16 to 32x32). App icons are the larger icons shown on device home screens and app stores (up to 1024x1024). Modern workflows generate both from a single high-resolution source image.

When to Use App Icon
Focus on app icons when building Progressive Web Apps (PWAs), native mobile apps, or any app that will be installed on a device home screen.
