Frequently Asked Questions
- What image size should I upload?
- At least 256×256 pixels gives the best downscaling quality. A square image works best since favicons are always square. The tool handles non-square images by fitting them inside the square canvas.
- Is my image uploaded or stored?
- Your image is sent to our server only to generate the ICO file and is immediately discarded. It is never stored or used for any other purpose.
- Does PNG transparency carry through to the ICO?
- Yes. The tool uses PNG encoding inside the ICO container, which preserves alpha transparency. Your icon's background will remain transparent in browsers that support it.
- Where do I put the favicon.ico file?
- Upload it to the root of your website (the same folder as your index.html). Then add <link rel="icon" href="/favicon.ico"> inside your <head> tag. Most browsers will also find it automatically at the root without any HTML.
