This is quite possible using either C or VB and IAC (InterApplication

The process you would have to follow would be:
1. Open PDF
2. Save As... PDF using the Linearised method. (&H4)
3. Close PDF.

You must reference the Acrobat.tlb file for this code to work

If you have any more question feel free to post them.


Here's some VB code to do just that (not tested):
Public Sub Optimize_PDF()

'/ Declare the Application
Dim Exch As Acrobat.CAcroApp

'/ Holds Information about the PDF document etc
Dim PDDoc As Acrobat.CAcroPDDoc

'/ Get the AViewing Layer
Dim AVDoc As Acrobat.CAcroAVDoc

'/ Assign an instance of the application and Window
'/ also create an instance of the PDDoc Layer to get
'/ to the Document properties
Set Exch = CreateObject("AcroExch.App")
Set AVDoc = CreateObject("AcroExch.AVDoc")
Set PDDoc = CreateObject("AcroExch.PDDoc")

'/ Like it was never there

'/ Put the Loop Here to Cycle through files if you wanted
'/ Open an example file. - Change the PDFFile to the name of your PDF file
IsOk = AVDoc.Open(PDFFile, "")
If Not IsOk Then
MsgBox "There was an error opening " & PDFFile & vbCrLf & _
"Currently there is no support for secure/signed PDFs or if your
using Acrobat Reader"
'/ Create an object through the Object Hierarchy
Set PDDoc = AVDoc.GetPDDoc

'/ Here's the magic line - write over the top of the file if you
'/ The codes for the different types of save methods
'/ can be found in the IAC.BAS file (from the SDK)
PDDoc.Save &H4, "Newfile.pdf"

'/ Close the file without prompting the user (the file should be
AVDoc.Close False
End If

'/ Close Acrobat

'/ Dispose of the evidence :-)
Set Exch = Nothing
Set PDDoc = Nothing
Set AVDoc = Nothing
End Sub
