Convert an image to ICO online

Do you want to convert an image into an ICO file to create a Windows icon, a favicon, or a graphic resource?

With Image to ICO, you can easily convert an PNG, JPEG or GIF image to the .ico format. Select your image, choose the desired size, then start the conversion to obtain your ICO file.

What is the ICO format?

ICO is a file format used especially to store icons on Windows. An ICO file can contain one or multiple icon images suited for different display sizes.

The .ico format is used for:

• Windows application icons;
• file and folder icons;
• certain user interfaces;
• Windows shortcuts;
• website favicons.

ICO files can contain icons of various dimensions, such as 16 × 16, 32 × 32, 48 × 48 or 256 × 256 pixels.

Convert PNG to ICO

The PNG format is especially convenient for creating an icon from an existing image. You can use your PNG logo or illustration as source, select the desired size, and generate your .ico file.

PNG to ICO is especially useful for creating an application icon, a Windows icon, or a favicon.

Convert JPG to ICO

You can also convert a JPG or JPEG image to ICO.

This conversion can be useful when your logo or image exists only in JPEG format and you need a .ico file for an application or another use that requires this format.

Convert GIF to ICO

The tool also accepts GIF images as source files.

Select your GIF image, choose the desired size, and generate your ICO file.

Create an ICO favicon

The ICO format has historically been widely used for favicons, those small icons associated with a website and displayed especially in tabs, bookmarks, or certain interface contexts.

To create a .ico favicon, you can start from your logo or another square image, then convert it with this tool.

A favicon.ico file can then be used as an icon resource for a website.

Note: modern websites can also use PNG or SVG favicons depending on needs and target browsers. The ICO format remains useful for certain compatibility scenarios and for environments that explicitly expect a .ico file.

What size to choose for an ICO image?

The size choice depends on the intended use.

Some common dimensions are:

Windows can use different dimensions depending on the display context. Providing multiple sizes allows the system to choose a more appropriate resource and limit unnecessary scaling.

Why convert an image to ICO?

ICO conversion is useful when the software or environment you are working with specifically expects this format.

You can use an ICO file to:

• create an icon for a Windows application;
• create a file or folder icon;
• prepare a favicon;
• convert an existing logo into an icon;
• prepare a graphic resource for a software project;
• have an icon in a format compatible with certain Windows tools.

ICO and PNG: what’s the difference?

PNG and ICO are two different formats that can be used for icons.

PNG is a widely used raster image format on the Web and in modern applications. ICO is a format specially designed for icons and can contain multiple representations of the same icon in a single file.

The choice therefore mainly depends on the software or platform where the image will be used.
