Admittedly, I am late to the party, but I have just started digging into PowerShell. The more I dig, the more I find that there is not much you cannot do in PowerShell.

Recently, I was browsing the forums and came across a post asking if it is possible to use LEADTOOLS in PowerShell to split multi-page PDF files into multiple single page PDF files. The answer is absolutely!

To get started, you need the LEADTOOLS assemblies and a license file. If you have not already purchased LEADTOOLS, you can download and request a 60-day evaluation license from our website. From there, all you need is a text editor to create your PS1 script file.

I have attached the complete PowerShell script to split a multi-page PDF into single pages. Below are some snippets so you can get an idea of how easy this is.

Use the LEADTOOLS License

The attached script has a function called Unlock-LT to encapsulate the code and do some validation, but in a nutshell:

$licenseFolder = "C:\LEADTOOLS21\License"
$binFolder = "C:\LEADTOOLS21\Bin\Dotnet4\x64"

$licenseFilePath = Join-Path -Path $licenseFolder -ChildPath "Leadtools.lic" 
$licenseKeyFilePath="$licenseFilePath.key"

Write-Verbose -Message "Reference the Leadtools Assembly"
Add-Type -Path (Join-Path -Path $binFolder -ChildPath "Leadtools.dll")

$licenseKey = Get-Content $licenseKeyFilePath
[Leadtools.RasterSupport]::SetLicense($licenseFilePath, $licenseKey)

Now that the LEADTOOLS PDF support is unlocked, we can use the PDFFile class to extract the pages.

Write-Verbose -Message "Reference the Leadtools.Pdf Assembly"
Add-Type -Path (Join-Path -Path $binFolder -ChildPath "Leadtools.Pdf.dll")

Write-Verbose -Message "Create instance of PDFFile class"
$pdfFile = New-Object -TypeName "Leadtools.PDF.PDFFile" -ArgumentList $srcFile

Write-Verbose -Message "Get number of pages in $baseFileName"
$pageCount = $pdfFile.GetPageCount()

for ($i = 1; $i -le $pageCount; $i++){
    $dstFilePath = "$baseDstPath - (page $i).pdf"
    $pdfFile.ExtractPages($i, $i, $dstFilePath)   
}

Splitting PDF files is just the tip of the iceberg of what is possible with LEADTOOLS and PowerShell. For my next PowerShell project, I think that I will start working on developing some cmdlets to make using LEADTOOLS even cleaner in PowerShell. Comment below if you have any requests!
