NOTE: DOC to PDF conversion is only one of many things this tool can do.  To learn more about 'Convert Doc's complete functionality see the on-line documentation. Of course please do download it and try it for free.

Convert Files by Command Line

What is the command line?  The command line is one of the most widely known, accepted and implemented methods for allowing one software app to initiate another app. That's why we've made it our goal to make all of our software command line able. Automate document conversions with the 'Convert Doc' command line using:

  • Simple bat files
  • Windows built in scheduler
  • 'Convert Doc's built in scheduler
  • Third party apps that have command line interfaces

Converting Word to PDF

  • Run 'Convert Doc' then select the 'Convert Files' action
  • Select the 'Convert Doc' conversion method and select your input file. If you are converting a whole folder of DOC files, select the folder and specify all the DOC files within it. For example to convert all the files in the folder "c:\My Files\" set the Input path to "c:\My Files\ *.DOC".  Note the use of the asterisk "*" character which is required when specifying a whole folder.  Next select the Input File Format which in this case is DOC or DOCX.
  • Specify the output file path and name. If you are doing a whole folder specify the output path with the asterisk " *" in the name. For example "c:\My Output Folder\ *.PDF" is correct. If not already done, choose the file type to convert to which in this case is PDF.
  • Click the CONVERT button (or F5) on the tool bar to start converting.

Converting PDF to Word

  • Run 'Convert Doc' then select the 'Convert Files' action
  • Select the 'Convert From PDF to ???' conversion method (the 'MS Word' method will also work) and select your input file. If you are converting a whole folder of PDF files, select the folder and specify all the PDF files within it. For example to convert all the files in the folder "c:\My PDF Files\" set the Input path to "c:\My PDF Files\*.PDF".  Note the use of the asterisk "*" character which is required when specifying a whole folder.

  • Specify the output file path and name. If you are doing a whole folder specify the output path with the asterisk " *" in the name. For example "c:\My Output Folder\*.DOC" is proper. Specify the file type to convert to by choosing the " Convert To File Format" which in this case is DOC (or DOCX).
  • Click the CONVERT button on the tool bar to start converting.

Repeating the use of a 'Conversion Job'

When you click the ADD button, a 'Conversion Item' is added to the 'task list' at the bottom of the user interface.  You can add as many 'conversion tasks' as you want, and save the 'Conversion Job' file for use at a later time.  See the File menu for saving and restoring 'Conversion Jobs'.
'Convert Doc' can be especially useful if you require complicated conversion jobs done on a regular basis. By saving and recalling a conversion job file, 'Convert Doc' quickly remembers all the file conversion tasks and their details.

Note: The same 'conversion job' file discussed above can be specified in the command line by using the /J switch. For example:
   ConvertDoc.exe /J"C:\my conversion Jobs\word-to-PDF.SII"

convert doc to pdf command line

Although we'll discuss the use of the command line here, it's only to give you a taste. For the full, accurate, and up to date information see the 'Convert Doc' command line documentation. There you will also find a full list of examples and how to troubleshoot.

NOTE: After installation, you can find several simple batch (*.bat) files for quick and easy usage by going to Start\All Programs\Convert Doc\Example Batch Files. These will work without modification provided the installation was in the default folder. Email us at  if you have any questions or need additional examples. We will get you up and running fast!

Basic syntax rules

  • You can include or exclude spaces between switches and parameters. For example:
    is the same as
    /C 6

  • Command line switches are case sensitive.

  • For long file names (e.g. a path or file name with spaces in it, or longer than 8.3 format) you may be required to use double quotes. A correct usage example is below:

    ConvertDoc.exe /J"C:\My Big Folder\MyJob.SII"

    Always using double quotes around paths will keep you out of trouble.

There are two approaches to using the command line:

  • Specify one or more conversion tasks in a 'Conversion Job'
  • Specify a single conversion task in detail

Specifying a Conversion Job

A 'Conversion Job' is easily built using the 'Convert Doc' graphical user interface. All the details of the job are saved in a single conversion job file (e.g. c:\myjobs\Do-Multiple-File-Conversion.SII). Specifying a conversion job with the command line is done by using the /J switch. You can have hundreds or thousands of tasks specified in the conversion job, all of which will get executed in one fell swoop.
The syntax for specifying a Conversion Job  is:

ConvertDoc /J{ConversionJobFile}  [/V] [/L{LogFile}]

Items above enclosed in square brackets '[ ]' are optional, all other 'switches' are required.  Therefore /J should always be specified on the command line when using this approach.


To run the 'Conversion Job' specified by "C:\MyJobs\ApplesOranges.SII," type the following in at the 'Command Prompt':

 ConvertDoc /J"C:\MyJobs\ApplesOranges.SII"

Specifying a 'Conversion Task'

Specifying a single conversion task requires a bit more effort, but does not require the prior creation of a 'Conversion Job' file. The syntax for specifying a conversion task is:

ConvertDoc /S{Input File(s)} /F# /T{Output File(s)} /C# [/M#] [/G] [/V] [/R] [/L{LogFile}]

Items enclosed in square brackets "[ ]" are optional, all other 'switches' are required. Therefore /S, /T, /C# should always be specified on the command line when using this approach.

Examples: Convert DOC to PDF by command line

NOTE: If you have trouble running these examples, see Using the Command Line and Helpful Hints For Creating a Command Line.


To convert a single file (for example: D:\MyFolder\Doc1.DOC to C:\Results Folder\Doc1.PDF), use the following syntax:

ConvertDoc /S"D:\MyFolder\Doc1.DOC"  /T"C:\Results Folder\Doc1.PDF"  /F9  /C12  /M2  /V

The /S and /T switches above specify Source (input) and Target (output) path respectively and are both required when converting a single file.
Use double quotes around the path, especially if there are space characters within the path.

The /M2 switch tells Convert Doc to use the Convert Doc method (it is one of the three possible conversion methods).

/F9 is the input file type, which in this case is a Word DOC file. The File Type Constants Specification for the Convert Doc method will show that the numeric value of 9 corresponds to a DOC file. Use 13 instead of 9 for DOCX.

/C12 is the output file type, which in this case is a PDF file. The File Type Constants Specification for the Convert Doc method will show that the numeric value of 12 corresponds to a PDF file. Use / C14 to convert to PDF/A-1b.

The /V (for Verbose) switch is used to give instant feedback by having the program report the status of the conversion with a message box. You can remove this once you have perfected your command line specification. You can also (or instead of /V) create a Log file that will contain the results of the conversion by using the /L switch.

Note: Use the Verbose (/V) switch initially to see what the status of your conversion is and to help you perfect your command line. In verbose mode, 'Convert Doc' displays messages to indicate what went wrong or right with your command line.

HINT: Use the /W switch to lock the pdf file with a File Open password. The Example below makes the word Apples the password to open the newly created PDF file:

     ConvertDoc.EXE     /S "c:\folder\tryme.doc" /T "c:\folder\tryme.pdf" /F9 /C12 /M2 /WApples


To convert all the DOC files in the D:\ToDo\ folder to PDF files in the same directory, use the following syntax:

ConvertDoc /S"D:\ToDo\*.DOC" /T "D:\ToDo\*.PDF" /F9 /C12 /M2

The /G switch can be used to tell Convert Doc to place the converted file in the same folder as it found the input.
The command line above is equivalent to the command line below:

ConvertDoc /S "D:\ToDo\*.DOC" /G /F9 /C12 /M2


To extend the previous example (immediately above) to convert all subfolders within D:\ToDo\,add the /R switch.

ConvertDoc /S "D:\ToDo\*.DOC" /G /F9 /C12 /M2 /R

To convert a whole folder and its subfolders and place the output into a separate folder/drive,use this syntax:

ConvertDoc /S"D:\ToDo\*.DOC" /T "C:\Done\*.PDF" /F9 /C12 /M2 /R
