PWA icons and splash screens: what you actually need
For most PWAs, a simple pair of PNG icons (192 and 512) plus a proper manifest.json is enough.
Minimal PWA set
- 192×192 PNG — Android home screen icon
- 512×512 PNG — large icon (often used during loading)
- manifest.json referencing both files
If your 512×512 is maskable, keep a safe zone so your mark won’t be clipped.
FAQ
Do I need more sizes?
Usually not. Extra sizes are mainly for legacy or edge cases.
Why does my splash look wrong?
Most often the manifest icon config or padding is off.
