'Convert Image to PDF' in brief

'Convert Image to PDF' is a simple to use, yet sophisticated file conversion utility designed specifically to convert images into PDF files. If you need to convert one or thousands of varying image file types into pdf, this is the tool.  The most popular task our customers perform is to convert JPG to PDF and TIFF to PDF.

'Convert Image to PDF' can be very useful if you require complicated conversion jobs be done regularly. With the user interface you can create any number of conversions and save it as a 'conversion job' file. By saving and recalling a conversion job file, the software quickly remembers all the details of the conversion tasks.

All of our conversion tools have numerous features. For example you can schedule a conversion job at a regular interval (time or calendar based) while optionally moving/deleting the input files. Also, our conversion tools have the ability to perform file operations and launch other programs.

'Convert Image to PDF' can be run from the command line allowing for use of batch files as well as being automated from other programs.

Image to PDF conversions by 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 conversions with the command line using:

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

What is the command line?

NOTE: After installation, you can find several simple batch (*.bat) files for quick and easy usage by going to Start\All Programs\Convert Image to PDF\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!

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 Image to PDF' command line documentation. There you will also find a full list of examples and how to troubleshoot. See using the Windows Scheduler also.

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. See Convert Image to PDF command line examples to get started quickly with specifying a conversion task or continue reading.

Specifying a 'Conversion Job'

Specifying a 'Conversion Job' is very easy, as you only need to tell 'Convert Image to PDF' where to find the associated *.SII 'Conversion Job' file.  This file is created within the user interface by setting up all the conversions you want and then saving it from the File menu. All the details associated with this conversion job are executed in one fell swoop.

The syntax for specifying a 'Conversion Job'  is:

 ConvertITP /J{ConversionJobFile}  [/V] [/L{LogFile}] [/B{LogToJobFile}]

Items above enclosed in square brackets "[ ]" are optional, all other ‘switches’ are required.  Therefore /J should always be specified on the command line.

To run the 'Conversion Job' specified by "C:\MyJobs\convert-PDF-to-TIF.SII" type the following in at the 'Command Prompt':
  ConvertITP /J "C:\MyJobs\convert-TIFF-to-PDF.SII"

You can include or exclude spaces between switches and parameters.  For example,  "/F6" is the same as "/F  6".  For long file names you may be required to use double quotes.  For example /J "C:\Program Files\MyApp\convert-BMP-to-PDF.SII".

Specifying a 'Conversion Task'

Specifying a 'Conversion Task' is a bit more tedious, but does not require the prior creation of a 'Conversion Job' file.

The syntax for the command line for specifying a conversion task is:


ConvertITP /S{Input File(s)} /T{Output File(s)} /F# [/G] [/V] [/R] [/L{LogFile}] [/B{LogToJobFile}] [/+] [/A{PDF Author}] [/D{PDF Creator}] [/K{PDF Keywords}] [/U{PDF Subject}] [/I{PDF Title}] [/Z] [/M#] [/W{Tiff Pages}]

NOTE: See also Convert Image to PDF command line examples to get going quickly.

Items above enclosed in square brackets "[ ]" are optional, all other 'switches' are required. Therefore /S, /T, /F# should always be specified on the command line. There is one exception, however, and that is when /G (Save to input folder) is specified, the /T switch is not necessary.

Command switches are case sensitive, therefore /T is completely different from /t.

You can include or exclude spaces between switches and parameters. For example, "/F6" is the same as "/F 6".

For long file names (e.g. a path or file name with spaces in it, or longer than 8.3 format) you are required to use double quotes. For example:

ConvertITP.EXE /S "C:\Input Folder\Coffee.bmp" /T "C:\Output Folder\CoffeeOut.pdf" /F0 /V


/S{Input File(s)} is used to specify which files to convert. You can specify a single file, or in some cases a whole set of files using the wildcard syntax (i.e. "C:\MyFiles\*.BMP"). /T{Output files} should always be different from /S{Input File(s)}.


/T{Output File(s)} is used to specify where to save the converted file(s) to. You can specify a single file, or in some cases a whole set of files using the wildcard syntax (i.e. "C:\MyFiles\*.BMP"). /T{Output files} should always be different from /S{Input File(s)}.


[/F#] tells ConvertITP what the input file type is. You must supply a number for the # symbol. Remember the input file type is specified by the / S{Input File(s)} switch. For all constants see File Type Constants.


[/G] Save output files to same folder as the input files. Use this instead of /T to place the converted files in the same folder as the input file. This cannot be used when /S specifies a single file. For single file use the /T switch instead.


[/V] Verbose mode. Specify this switch to display a message box indicating success or failure after the job has run. If a failure occurred a reason is usually displayed. See also /L.


[/R] Seek out and do all files found in the sub-folders specified by the /S switch. You may add this switch if you are processing whole directories of files. See /S, /T and /G for more details on selecting whole directories to be converted.


[/L{LogFile}] Log file path and name (i.e. d:\mylogs\CITP.LOG). If this switch is used a log file will be created and the results of the conversion will be written to it. See also /V.


[/B{LogToJobFile}] Save the Log file as a 'Conversion Job', but only if errors occurred. This is useful if the files that had problems can be done at a later time, or with a different method. /B is different from /L, since the file generated with /B will not include extraneous comments not allowed in a 'Conversion Job' file. Save as a .SII file type so it can be loaded as a job.


[/Z] Verbose Log. All file operations will be recorded in the log


[/+] Append (concatenate) image to the end of a PDF file.

[/A{PDF Author}] Specify the Author property of the PDF file.

[/D{PDF Creator}] Specify the Creator property of the PDF file.

[/K{PDF Keywords}] Specify the Keywords property of the PDF file.

[/U{PDF Subject}] Specify the Subject property of the PDF file.

[/I{PDF Title}] Specify the Title property of the PDF file.


[/M#] TIFF ONLY: Compression Method. 0 = No compression, 1 = LZW, 2 = RLE Compression (1bpp), 3 = CCITT3 Compression (1bpp), 4 = CCIT4 Compression (1bpp)

[/W{Tiff Pages}] TIFF ONLY: Which pages to convert. You can specify the pages individually or by ranges, separated by commas. For example "/W 1,2,3,10,11" is the same as "/W 1-3,10-11".

Examples of JPG to PDF Conversion by Command Line

Example 1: Single File Conversion

Specify the source (/S) and target files (/T), the JPG format (/F2) of the source file, with on-screen confirmation (/V):

ConvertITP.EXE /S "C:\Samples\Coffee.JPG" /T "C:\Samples\Output\CoffeeOut.pdf" /F2 /V


Example 2: Single File Conversion With Log File Creation

Specify the source (/S) and target files (/T), the JPG format (/F2) of the source file, and create a log file (/L) containing the confirmation information:


ConvertITP.EXE /S "C:\Samples\Ripple.JPG" /T "C:\Samples\Output\Ripple.pdf" /F2 /L"C:\Samples\LogFiles\OutputLog.LOG"


Example 3: Single File Conversion, Specify PDF Attributes

Specify the source (/S) and target files (/T), the JPG format (/F2) of the source file and specify Author (/A), Keyword (/K) and Title (/I) properties for the .pdf file.  Note that, after creating the .pdf file, properties can be viewed through Internet Explorer by right clicking on the file, displaying properties then selecting the PDF Properties tab:


ConvertITP.EXE /S "C:\Samples\InputFile.JPG" /T "C:\Samples\Output\Icon.pdf" /F2 /A SoftInterface.com /K Logo /I  Application Logo


Example 4: Whole Folder Conversion

This example shows you how to convert all files of a particular type within a folder by using the wildcard (*).  Specify the source (/S), in this case all JPG files in the Samples folder, the target (/T), and .jpg format (/F2) of the source files.  Display on-screen confirmation (/V) and create an error job file (/B) only if an error in conversion occurs:


ConvertITP.EXE /S "C:\Samples\*.JPG" /T "C:\Samples\Output\*.pdf" /F2 /V /B "C:\Samples\ErrorLogs\Error.SII


Example 5: Whole Folder Conversion, Place output in Original Folder

Convert all JPG files in the Output folder using the wildcard (/S), save them to the same folder as the originals with the same names (/G).  Create a log file (/L) with results of the conversion and create an error job file (/B) only if an error in conversion occurs:


ConvertITP.EXE /S "C:\Samples\Output\*.JPG" /G /F2 /L "C:\Samples\LogFiles\OutputLog.LOG" /B "C:\Samples\ErrorLogs\Error.SII

"I was surprised to see, that when a tiff file exceeds a certain size, then Acrobat's own conversion do not work. The image is mirrored and/or stretched. But your software works perfectly! We have some large geophysical logs (for example 3507 x 52761 pixels) that couldn't be handled in Acrobat.
