ICO files are used as favicons in browser tabs and as application or shortcut icons in Windows. If you have a .jfif image — a logo, icon, or screenshot — and need an .ico for your site or app, this tool creates it in seconds. You can often generate multiple sizes (e.g. 16×16, 32×32, 48×48, 256×256) in one ICO file. Everything runs in your browser; your file never leaves your device.
What is JFIF to ICO?
JFIF is the same image format as JPG. ICO is a format for icons: it can hold multiple resolutions (e.g. 16×16, 32×32, 256×256) in one file. Converting JFIF to ICO turns your image into an icon file that browsers use for favicons and Windows uses for app and shortcut icons. The tool usually resizes and encodes your image into the ICO structure.

JFIF to ICO online vs desktop apps

Tips for best results
Before you convert:
- Favicons and icons are usually square. If your image isn't square, crop or resize it first for best results.
- Include 16×16 and 32×32 at least for favicons; 48×48 and 256×256 help for Windows and high-DPI.
- Simple, high-contrast images work best at small sizes.
- If the tool offers a crop step, use it to centre the important part in a square.
- You can also drag .jpg files here; the tool will process them the same way.
- Test your favicon in several browsers and on mobile after uploading.
- Some systems accept PNG for favicons; ICO is still widely used and holds multiple sizes.
