An ICO file is commonly used when a website, desktop application or software project needs an icon resource. A favicon can use a small ICO image, while application interfaces may require larger icon resolutions.
With this converter, you can choose the exact output sizes instead of generating unnecessary files. 32×32 is selected by default, while 16×16, 24×24, 48×48, 64×64, 128×128 and 256×256 are available when your project needs them.
Transparent backgrounds are useful for logos and favicons because the icon can blend into different page or application backgrounds. The converter keeps processing in the browser, so the source image does not need to be uploaded to a conversion server.
ICO is an icon file format commonly used for website favicons, Windows icons and application icons. An ICO can contain icon image data at a specific resolution.
You can upload PNG, JPG, JPEG, WEBP, BMP, GIF and SVG images. The conversion happens in your browser.
The converter supports 16×16, 24×24, 32×32, 48×48, 64×64, 128×128 and 256×256 pixels. You can select one or multiple sizes.
32×32 is a useful default for a standard favicon. You can also generate 16×16 and 48×48 when your project requires additional favicon sizes.

The current generated outputs are reset to pending so the next Generate ICO action uses the newly selected sizes. This prevents downloading files generated with old settings.
Each selected size is generated as a separate ICO file. For example, selecting 16×16, 32×32 and 48×48 creates three ICO files for each uploaded image, packaged together as a ZIP when appropriate.
