Frequently asked questions
- What sizes do I need for a favicon?
- At minimum: favicon.ico (32x32), apple-touch-icon.png (180x180), and android-chrome (192x192, 512x512). SnapOtter generates all of these plus intermediate sizes in a single ZIP.
- What image format works best as a favicon source?
- Use a square PNG with transparency (at least 512x512 pixels). SVG sources also work well since they scale cleanly. Avoid photos or complex images that lose detail at small sizes.
- Do I need a web manifest for favicons?
- For PWAs and Android home screen icons, yes. SnapOtter includes a manifest.json snippet with your generated icons already referenced.
