Image to Icon Converter PowerShell Script

This PowerShell script converts an image (in formats such as SVG) into a multi-size ICO icon. The script uses Inkscape to generate PNG images at different resolutions and ImageMagick to combine these images into a single .ico file. Temporary files created during the process are automatically cleaned up.

Features

  • Generates icons with multiple resolutions: 256x256, 128x128, 64x64, 48x48, 32x32, 24x24, and 16x16 pixels.
  • Automatically finds magick.exe (ImageMagick) in the system's PATH or a common installation directory.
  • Uses Inkscape to handle SVG image conversion.
  • Cleans up temporary files after conversion.

Requirements

  • Inkscape: The script uses Inkscape to export PNG files. You need to have Inkscape installed and accessible at the path C:\Program Files\Inkscape\bin\inkscape.com. Adjust the path if your installation is located elsewhere.
  • ImageMagick: The script uses ImageMagick’s magick.exe command to generate ICO files. It attempts to find magick.exe in your system's PATH. If not found, it falls back to a common installation path: C:\Program Files\ImageMagick-7.1.1-Q16-HDRI\magick.exe.

How it works

  1. Input Image: The script takes a single image file (such as an SVG) as input.
  2. Generate PNGs: It uses Inkscape to generate PNGs in different sizes (256x256, 128x128, 64x64, 48x48, 32x32, 24x24, and 16x16 pixels).
  3. Create ICO: The script then uses ImageMagick to combine the PNG files into a single .ico file.
  4. Clean-up: Finally, it cleans up the temporary directory where the PNG files were stored.

Usage

Syntax

.\ConvertToIcon.ps1 -ImagePath <path_to_image_file>

Example

.\ConvertToIcon.ps1 -ImagePath "C:\Images\logo.svg"

This command will convert the logo.svg image into a .ico file containing multiple resolutions, saved in the same directory as the original image.

Parameters

  • -ImagePath: The full path to the image file (SVG or another format supported by Inkscape).
