Why it matters: The 256x256 favicon gives crisp detail for modern high-res displays and app stores. Ship it alongside the other sizes so every device shows your icon at its best.

How to create a favicon

  1. 1Choose a source — upload an image or logo, type text, or pick an emoji.
  2. 2Pick your sizes and format — ICO for maximum compatibility, PNG for quality and transparency.
  3. 3Generate and download. Grab individual files or a single ZIP of every size.

Best settings for this page: Open the tool, choose the 256x256 size (or let this page lock it), and download the ICO or PNG.

All processing runs locally in your browser. Your files are not uploaded to any server.

Favicon formats: ICO vs PNG vs SVG

ICO — the original favicon format. One .ico file can hold several sizes, so browsers pick the best fit. Best for universal compatibility.

PNG — modern browsers treat PNG favicons as first-class images. PNG keeps transparency, so it is ideal for icons with a cutout or soft edges.

SVG — resolution-independent and tiny, but still limited mostly to Chromium-based browsers. Great as a progressive enhancement alongside ICO/PNG.

For full coverage, ship an ICO plus a set of PNG sizes (and a manifest). Generate them all here with no uploads.
