GIF (Graphics Interchange Format) is a bitmap image format that supports up to 256 colors and animations. GIFs are widely used for simple animations and graphics on the web.
ICO (Icon) is a specialized image format used for Windows icons and website favicons, supporting multiple sizes and color depths in a single file.
This converter transforms your GIF images into ICO format with multiple icon sizes in a single file. Since ICO files don't support animation, only a single frame from your GIF will be used to create the icon.
