What is favicon.ico?
favicon.ico is the classic website icon shown in browser tabs, bookmarks, and shortcuts. A single .ico file can contain multiple resolutions so it stays sharp on retina displays and older Windows shells. This tool builds that pack locally from your logo — nothing is uploaded.

Frequently Asked Questions
- Are my images uploaded?
- No. Cropping, rounding, and ICO encoding run entirely in your browser.
- Which sizes are in the full favicon pack?
- The all-sizes download embeds 16, 32, 48, 64, 128, 256, and 512 pixel frames in one favicon.ico file.
- Can I download only one icon size?
- Yes. Use the single-size download after generating to get an .ico with only your preview size.

- How is this different from the image converter?
