Meet Google Chrome and Apple WebKit Progressive Web App installation requirements.
1. Mandatory Icon Resolutions for Progressive Web Apps
To enable the native 'Install App' prompt in Google Chrome, a web application must define at least two standard raster PNG icons: 192x192 px for standard home screen launcher icons, and 512x512 px for splash loading screens.
2. The Importance of Maskable Icon Padding
Android adaptive icon shapes vary across device manufacturers. Always leave a 10% safe margin around your central glyph so that adaptive masking does not crop the outer edges of your brand logo.
