Why use ZillaKit's PNG to ICO Converter?

Most favicon makers ask you to upload your image to a remote server, which is slow and puts your artwork on someone else's machine. ZillaKit does everything right inside your browser using the canvas and a small JavaScript ICO encoder, so your files never leave your device. That means instant conversion with no queue, no watermark, and no signup. You get a genuine multi-resolution .ico file — the same container format Windows and browsers expect — with each size rendered from your original for maximum sharpness. The free tier covers everyday use, and because the tool is fully client-side it keeps working even on a flaky connection. Whether you are shipping a personal blog or a production web app, you get a clean, standards-compliant favicon in seconds, plus an optional pack of matching PNGs for modern touch icons.

FAQ

What sizes should a favicon include?

16×16 and 32×32 cover browser tabs and bookmarks. Adding 48×48 helps Windows, and larger sizes like 128 or 256 are useful for high-density displays and app tiles.

Is the ICO file valid on old browsers?

Yes. The ICO container embeds PNG images for every selected size, which is supported by all modern browsers and Windows Vista and later. For very old systems, keep 16 and 32px included.

Do my images get uploaded anywhere?

No. Everything runs locally in your browser with the HTML canvas. Nothing is sent to a server, so your artwork stays private.

What is in the favicon pack?

A zip containing favicon.ico plus a PNG for each size you selected (for example favicon-32.png), ready to reference from your HTML head.
