What is an ICO file?

ICO is a multi-resolution image format used for favicons and Windows application icons. A single .ico file can contain multiple sizes (16×16, 32×32, 48×48, etc.) and your browser or OS picks the best one for each context.

Common uses:

  • Favicon — the small icon in browser tabs. Use sizes 16, 32, 48.
  • Windows app icon — desktop shortcuts and taskbar. Use 16, 32, 48, 256.
  • PWA icon — installable web apps. Use 192 and 512 (PNG preferred, but ICO works).
  • Bookmark icon — shown in bookmarks bar. Use 16 or 32.
Runs 100% in your browser using the Canvas API. Your image never leaves your device.
Tip: Start with a square image (at least 256×256) for best results. Transparent PNGs produce the cleanest favicons.
