Image to ICO Converter — Free Online Images Converter
Creating a favicon.ico for your website used to require image software; now you can generate one in seconds. Our image to ICO converter takes a JPG, PNG, or WEBP logo, center-crops it to a square, and produces a multi-size ICO file with 16, 32, and 48px versions built in — exactly what every browser looks for.
The whole process runs in your browser using the HTML5 Canvas API, so your artwork is never uploaded. Multi-size output means your favicon stays crisp in browser tabs, bookmarks, and the taskbar.
Perfect for new sites, rebrands, and web apps: upload a logo, download favicon.ico, and drop it into your site's root folder — done.
