A good favicon needs to stay readable at tiny sizes. Start with a square image or logo, avoid small text, and check the 16px and 32px previews before downloading. Simple shapes, strong contrast, and a little padding usually work better than detailed photos. If your source image is rectangular, crop it to the main symbol first so the browser tab icon does not feel cramped.
Modern websites can use PNG favicons, and many sites also add multiple sizes for pinned tabs, app shortcuts, and browser UI. This generator is designed for quick local favicon preparation: upload, crop, touch up, download, then add the favicon link tag to your site. Your logo file stays in your browser while you work.
