Image conversion is a crucial task in many scenarios, whether it's for resizing, format conversion, or optimizing images for different purposes. In the Windows environment, there are several tools and techniques available to perform image conversion efficiently. This article aims to provide a comprehensive guide on image conversion, focusing on the Windows platform.

Examples:

1. Using Command-Line Tools:
One of the most common ways to perform image conversion in Windows is by utilizing command-line tools such as ImageMagick or GraphicsMagick. These tools provide a wide range of options to manipulate and convert images. For example, to convert an image from PNG to JPEG using ImageMagick, you can use the following command:

   magick convert input.png output.jpg

This command will convert the "input.png" file to "output.jpg" in the current directory.

2. Batch Conversion with PowerShell:
PowerShell is a powerful scripting language in Windows that can be used to automate image conversion tasks. To perform batch image conversion using PowerShell, you can utilize the .NET framework's System.Drawing namespace. Here's an example script that converts all PNG files in a directory to JPEG:

   $inputPath = "C:\Images"

   $outputPath = "C:\ConvertedImages"



   $files = Get-ChildItem -Path $inputPath -Filter "*.png" -File



   foreach ($file in $files) {

       $image = [System.Drawing.Image]::FromFile($file.FullName)

       $outputFile = Join-Path -Path $outputPath -ChildPath ($file.BaseName + ".jpg")

       $image.Save($outputFile, [System.Drawing.Imaging.ImageFormat]::Jpeg)

       $image.Dispose()

   }

This script iterates through all PNG files in the specified directory, converts each image to JPEG format, and saves it to the output directory.
