16, 32, 48, 64, 128 and 256 px versions packed into a single .ico file.

The icon is generated locally — nothing is uploaded.
No account, no watermark, no limits.

Add your PNG to the tool above, tick the sizes you want and start the conversion. The multi-size .ico downloads instantly — free, no account.
16 px for browser tabs, 32 px for shortcuts and bookmarks, 48 px and up for Windows desktop and taskbar icons. One .ico holding several sizes lets every context pick the sharpest one.
Browsers and Windows inspect the real file format — a renamed PNG breaks in strict contexts and some browsers ignore it. This tool builds a genuine ICO container with embedded images.
Upload the file to your site root (usually as /favicon.ico) and add <link rel="icon" href="/favicon.ico"> to your pages. Most browsers also find it automatically at the root.
It is fitted inside a square canvas with transparent padding, so nothing is cropped or stretched. For edge-to-edge icons, crop your PNG square first with the Crop Image tool.
No. Everything runs entirely in your browser — the file never leaves your device.
