Optimizing Image Assets for Progressive Web Apps
PWA developers need to optimize all image assets for offline-first experiences. App icons, splash screens, and content images must be served in multiple resolutions and modern formats while keeping the total cache footprint minimal.
Workflow
- Catalog all image assets required by the PWA (icons, splash screens, content images)
- Use the Image Resizer to generate each asset at required sizes (72, 96, 128, 144, 192, 384, 512px)
- Use the Image Converter to produce WebP versions for modern browsers
- Use the Image Compressor to minimize the cache storage footprint
- Create JPEG fallbacks for browsers without WebP support
- Update the web app manifest with all icon size declarations
- Test the PWA install experience on Android and iOS
