How to Convert ICO to ICNS

By Diana Braun

The ".ico" file extension identifies an icon file on a Windows computer. If you want to use that same icon file on a Mac computer, you must convert it to an ICNS file, which is the file type associated with icons on a Mac. An online icon conversion tool can help you easily convert an icon file from the ICO extension to a Mac-compatible ICNS file.

Step 1

Launch a Web browser and navigate to a website that offers an icon conversion tool such as Iconverticons.com.

Step 2

Convert your ICO file using the "Browse" feature of the site.

Step 3

Click the “Convert” button.

Step 4

Click the “Save” button when prompted to save the converted ICNS file locally to your computer.
