What image formats can I upload?

PNG, JPG, WebP, SVG, and GIF are all accepted. For best results use a square PNG with a transparent background.

Is my image uploaded to a server?

No. All processing happens entirely in your browser using the HTML Canvas API. Your image never leaves your device.

What is the manifest.json snippet for?

The manifest.json icons array is required for Progressive Web Apps (PWAs). It tells Android and Chrome which icon sizes to use when installing your web app to a home screen.

What Sizes Does a Favicon Need?

Modern browsers and devices require favicons at multiple resolutions. The classic 16×16 and 32×32 sizes cover desktop browser tabs. The 180×180 Apple Touch icon is used when someone adds your site to their iOS home screen. The 192×192 and 512×512 sizes are required for Progressive Web App manifests on Android.

Tips for a Great Favicon

Start with a square image at least 512×512 pixels. Simple designs — a single letter, icon, or logo mark — read far better at small sizes than detailed illustrations. Use a transparent background so the favicon adapts to light and dark browser UIs.
