Turn any square logo or image into a standard multi-resolution .ico favicon file.
A favicon is the small icon browsers show in tabs, bookmarks, and history. This tool packages your logo or image into the standard multi-resolution .ico container format every browser expects.
Use a square logo or icon for the cleanest result — the tool will center and scale non-square images automatically.
Multiple icon sizes (16x16, 32x32, 48x48, and more) are bundled into a single .ico file for crisp rendering at any size.
Download the generated `favicon.ico` and drop it into your website's root directory or `<head>` tag.
Everything you need to know about this developer tool
The generated .ico file bundles the standard set of resolutions (including 16x16, 32x32, and 48x48) so browsers can pick the sharpest size for tabs, bookmarks, and shortcuts.
A square image gives the best result since favicons are square. Non-square images are automatically center-cropped or scaled to fit.
Yes, briefly. To build the multi-resolution .ico file, your image is sent over an encrypted HTTPS connection to our server, processed in memory, and returned immediately — it is never stored, logged, or shared.
