Formule & Méthode de Calcul
Master Image (512x512) ➔ Canvas Scaling ➔ [16x16, 32x32, 192x192, 512x512]
The algorithm takes a high resolution master file and mathematically interpolates it down to the exact dimensions required by Google Android (192px) and Apple iOS (512px).
Bonnes Pratiques & Conseils
- Keep It Simple: A 16x16 pixel square is microscopic. Never use text or complex photographic logos for a favicon. Use a highly simplified, high contrast vector monogram or solid icon.
- Use Transparent PNGs: Always upload a master file with a transparent background. This allows the device OS (like iOS or Android) to apply their own native rounding masks (like squircles) gracefully.
- Don't Forget the Manifest: For Android devices to recognize your app icons, you must include a `site.webmanifest` JSON file in your root directory that points to the exact paths of the 192x192 and 512x512 PNGs.
