[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Office.Word.Server")

# Input parameters for the script

      $wordFile="http://xyz:31000/SampleDocToPDF/Test2.docx"

      $pdfFile=" http://xyz:31000/SampleDocToPDF/Test2.pdf"

# Get the Word Automation Service Proxy

$wasp = Get-SPServiceApplicationProxy | where { $_.TypeName -eq "Word Automation Services Proxy" }

      Write-Host " Word Automation Proxy Name : " $wasp

#Create the Conversion job

     $conversionJob = New-Object Microsoft.Office.Word.Server.Conversions.ConversionJob($wasp)

      Write-Host " Conversion Job created : " $conversionJob

# Get the web url

     $web = Get-SPWeb "http:// xyz:31000/"

      Write-Host " Accessing Site : " $web

# Set the credentials to use when running the conversion job.

     $conversionJob.UserToken = $web.CurrentUser.UserToken

      Write-Host " Accessing current user token"

# Conversion Job Name

    $conversionJob.Name = "Convert docx to PDF"

    $conversionJob.Settings.OutputFormat = [Microsoft.Office.Word.Server.Conversions.SaveFormat]::PDF

    $conversionJob.AddFile($wordFile,$pdfFile)

# Start the conversion job

      Write-Host " Conversion Job Started....  "

    $conversionJob.Start()
