How to use

Upload an image, drag the crop area and preview the result, pick ICO sizes, then download .ico files — ideal for favicons or desktop shortcuts.

  1. Add one or more images (PNG, JPG, WebP, etc.) by drag and drop or browse.
  2. Drag the crop box to choose the icon area; live 32×32 and 64×64 previews appear on the right.
  3. Check the sizes you need (e.g. 16, 32, 48, 256) or use the favicon preset.
  4. Click Generate ICO to process all files in the queue.
  5. Download individual .ico files or all results as a ZIP.
All processing runs locally in your browser — your images are never uploaded to any server.

FAQ

What is an ICO file?

ICO is a container format used by Windows and browsers. One .ico file can hold several sizes (16×16, 32×32, 256×256); the system picks the best match for each context.

Which sizes should I include?

For website favicons, 16, 32, and 48 px are common. Add 128 and 256 for sharper taskbar or PWA icons. This tool includes all standard sizes by default.

Are my images uploaded?

No. Generation runs entirely in your browser; files never leave your device.

How do I use the ICO after download?

Place favicon.ico in your site root and reference it in the page head with a link tag (rel="icon", href="/favicon.ico"). You can also use it for app packaging or desktop shortcuts.
