ICO is a container format that can contain multiple icons.
This is a batch script to extract icons from ICO files, and optionally convert them to any format.
- Install ImageMagick, if you haven't already.
- Download extract_icons.bat to any folder.
- (Optional) If you want to be able to use this script in the command line from any folder like a normal program, add the script's folder to your Path environment variable.
Run the script in a command prompt.
Usage: extract_icons {input_file} [outfiles_format]
{input_file} is the file you want to extract from.
[outfiles_format]: Optional parameter. If you want to convert all icons to a perticular format, specify it here, after {input_file}. If not specified, the icons will only be extracted, not converted.
If ImageMagick gives you an error, it might be that the file only contains one icon.
As a fallback, you might want to convert the file instead: magick {input_file} {output_file}
Example: magick my_icon.ico my_icon_converted.png
If you want to put one or multiple images into an ICO container (assemble into one ICO file):
- Put all pictures alone in one folder.
- In that directory, run
magick * {output_file}
