Convert ICO files online for free
The converter easily converts your ICO file to various formats - free and online. No Notepad or extra software needed.
The converter also works in reverse, so you can convert other Raster Image formats to ICO with high quality output.
.ICO is the standard container format used by Microsoft Windows to store system icons. Unlike a standard image file, a single .ICO acts as a wrapper containing multiple raster images at various resolutions (e.g., 16x16, 32x32, 48x48, and 256x256) and color depths. This allows Windows to scale the icon cleanly from a tiny Taskbar item to a large Desktop shortcut. While essential for software development and website favicons, the format is proprietary and cumbersome for general use. .ICO files are not supported by most web browsers for standard image display, are difficult to view on mobile devices, and require specialized tools like IcoFX or GIMP to edit individual layers without breaking the container.
For general graphics work, web design, or sharing, converting .ICO to PNG is the best solution as it preserves the critical transparency (alpha channel) while ensuring universal compatibility. For developers moving assets to the Apple ecosystem, converting .ICO to ICNS is necessary. If you need to check the contents of an icon or extract a high-resolution logo from a system file, simply drag and drop it here to convert it to a standard image format.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ICO converter.
