'Convert PDF to Image' FAQ

Fast, accurate and easy to use PDF to Image Conversion Tool



After Conversion, and while viewing the PDF in Adobe, a message pops up asking to check for upgrades

Note: Our tool does not require 3rd party products such as Adobe's for the conversion. The message box that is popping up is generated by Adobe Acrobat Reader.  It occasionally checks the internet for updates to itself.    This message is shown because it is illegal to send any information over the internet without the user's permission.  Disable this message by opening Acrobat Reader and selecting Edit -> Preferences from the menu at the top.  In the new window, select Update.  On the options that appear on the right, select "Manually" in the Check for Updates box.

What Version of PDF does your software generate?

There are several generations of the PDF format.  For example, version 1.5 was released with Adobe Acrobat v6.0.  Convert Image to PDF uses the previous generation (v1.4).  There are very few changes to the version 1.5, but some are quite significant.   We do not plan on changing to the v1.5 PDF format for a couple of reasons.  The first is that the imaging portion of the PDF format has only changed slightly in version 1.5.  The most notable change is that they've added support for JPEG 2000.   The second major change in the PDF format is a new compression algorithm they developed. It is mainly a text compression routine.  This is the first version of the PDF format that is NOT backwards compatible.  All other versions (1.0-1.4) can be viewed or printed in many of their Acrobat Reader programs.  If this compression is used, the end viewer must be Acrobat Reader v6.0 or above.

I get the following error when I run from the command line

"ConvertPDFtoImage" is not recognized as an internal or external command, operable program or batch file."

IMPORTANT: To use the command line successfully the operating system will need to know where exactly the application is located. Otherwise, you'll see the following error:

"ConvertPDFtoImage" is not recognized as an internal or external command, operable program or batch file."

We suggest you do one of the following:

A)    Set the path in your operating system's environment variables to the installation location of ConvertPDFtoImage.EXE. See your operating system's help for setting the path.

B)    Create a batch file (a text file whose file name ends in .bat) that uses the fully qualified path of ConvertPDFtoImage.EXE.

For example the following is a typical batch file:

"C:\Program Files\Softinterface, Inc\Convert PDF To Image\ConvertPDFtoImage.EXE" /S"C:\In\Coffee.pdf" /C1 /T "C:\Out\Cream.jpg" /1 * /4 75 /5 200 /V

You may also be able to do something like this in a batch file:

set ConvertPDFtoImage ="C:\Program Files\Softinterface, Inc\Convert PDF To Image\ConvertPDFtoImage.EXE"

ConvertPDFtoImage /S"C:\In\Coffee.pdf" /C1 /T "C:\Out\Cream.jpg" /1 * /4 75 /5 200 /V

One more possibility is to simply change the active folder before calling the application:

CD C:\Program Files\Softinterface, Inc\Convert PDF To Image

ConvertPDFtoImage /S"C:\In\Coffee.pdf" /C1 /T "C:\Out\Cream.jpg" /1 * /4 75 /5 200 /V

Also, it is suggested you us fully qualified paths for any files you specify.
