Frequently Asked Questions
What is an ICO converter?
An ICO converter is a free online utility that converts standard image files—such as PNG, JPG, WebP, SVG, or GIF—into Microsoft Icon (.ico) format, commonly used for website favicons and Windows desktop icons.
What is a favicon.ico file?
A favicon is the small icon displayed next to a website's title in browser tabs, address bars, bookmark lists, and search engine results. The standard filename expected by browsers at the root of a domain is favicon.ico.
Does this ICO converter support transparency?
Yes! If you upload a transparent PNG, WebP, or SVG logo, our converter preserves the transparent background so your favicon displays cleanly without an unwanted square border.
How do I add the converted ICO favicon to my website?
Upload the converted favicon.ico to your website's root directory, and add this line inside your HTML <head> section: <link rel="icon" href="/favicon.ico" type="image/x-icon">.
Can I convert multiple images to ICO simultaneously?
Yes. You can upload multiple logos or images at once and download them individually or as a single ZIP archive.
Is this ICO converter free to use?
Yes, it is 100% free with no registration, no watermarks, and no usage limitations.
