'Convert Image to PDF' is a Windows tool from SoftInterface that converts 23 image formats — including TIFF, JPG, BMP, GIF, PNG, ICO, PCX, PSD, TGA, JNG, MNG, RAS, WBMP, and more — into PDF files. It runs from a graphical interface or the command line, supports unattended batch processing of entire folders, and requires no additional software.
The tool combines many images into a single PDF or generates one PDF per image, appends images to an existing PDF (useful for adding new pages to an archived document), selects specific pages from multi-page TIFFs, applies TIFF compression options (LZW, RLE, CCITT3, CCITT4) for archival workflows, and sets PDF metadata fields (Author, Title, Subject, Keywords, Creator) per output file. Batches resume from interruption, recursive folder processing is built in.
'Convert Image to PDF' is used by the Geological Survey of Denmark (GEUS) for converting oversized geophysical logs that exceed Adobe Acrobat's image-size handling, and by many of the world's largest corporations for document archiving, scan-to-PDF workflows, e-discovery, and digital records management. Free 30-day trial and 30-day money-back guarantee on every purchase.
'Convert Image to PDF' converts in an instant. It also allows for the saving and restoring of complex 'conversion jobs'. Specify a 'conversion job' within the command line or Windows scheduler and rest easy.
Command line capability is at the core of all our software tools. Demo batch files are installed ready for testing and modification. We are always here to help you implement our software.
Moving or deleting input files while converting to PDF is easy to do. This allows for unattended conversion of whole folders.
Plenty of image-to-PDF converters exist. A few reasons users pick 'Convert Image to PDF' over the alternatives:
Local processing — your images stay on your machine. Most online converters require uploading your images to their servers. 'Convert Image to PDF' runs entirely on Windows; nothing leaves your computer. Decisive for legal, medical, financial, and government workflows where image contents are confidential — and for any document containing PII, scanned IDs, financial figures, or client data.
23 input formats, including oversized TIFF. TIFF, JPG, BMP, GIF, PNG, ICO, PCX, PSD, TGA, JNG, MNG, RAS, WBMP, and more — including very large images that Adobe Acrobat mirrors or stretches during its own conversion. Users have successfully converted images of 3507 × 52761 pixels and beyond. TIFF compression options (LZW, RLE, CCITT3, CCITT4) are exposed for archival workflows. Multi-page TIFFs can have specific pages selected for conversion.
Built for production batches. Drive jobs from Windows Task Scheduler, BAT files, COM/ActiveX, or the built-in scheduler. Save complex jobs as reusable .SII files. Combine many images into one PDF, generate one PDF per image, or append images to an existing PDF. Set PDF metadata (Author, Title, Subject, Keywords, Creator) per output file. Batches resume from interruption; recursive folder processing is built in.
Risk-free evaluation. Free 30-day trial with full functionality — no time-bombed features. 30-day money-back guarantee after purchase if it doesn't fit your workflow.

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:
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:
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.
Example:
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' 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".

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