Detailed Change History

15.40 (6/6/2023)

  • Moving a licenses between two computers with Windows 11 was failing.

15.30 (1/3/2023)

  • Application load time reduced. The number of input/output files within the drop down list box was reduced from 10 to 6 for faster load times. Scheduling form job source most recently used list was reduced from 20 to 10.

15.20 (12/07/2022)

  • Documentation updated for accuracy and completeness.

15.10 (8/25/2022)

  • Bug fix: Specifying advanced page ranges when converting to single file TIFF was causing a crash.

15.00 (2/6/2022)

  • Certified Windows 11 compatibility

14.10 (12/11/2020)

  • Registration issue resolved. Users who are attempting to upgrade options (e.g. Server upgrade) and already had registered all users were running into problems. The newly purchased options were not being implemented.

14.00 (10/30/2020)

  • Sample batch files had incorrectly referenced the incorrect URL for further examples.
  • These sample batch files have been updated for clarity also.
  • Sample batch files are available in this folder after installation:

  • %appdata%\SoftInterface, Inc\Convert PDF to Image\Demo Batch Files\

13.553 (2/6/2020)

  • Documentation updated for accuracy.
  • Tutorial Videos updated. Note: Softinterface Apps 'Convert Image to PDF' and 'Convert PDF to Image' have nearly identical user interfaces, and therefore use this video for both. They are now hosted on YouTube as a watchlist.

13.30 (6/1/2019)

  • User interface: Brazilian-Portuguese language localization file added.

13.20 (3/8/2019)

  • User interface: Language selection dialog had a bug. Closing using the top right 'control box' we cause app to revert to English.

13.00 (10/29/2018)

  • Documentation updated to show videos properly

12.50 (3/22/2018)

  • Command Line: Using /L{Log File} switch created an extra output log file.

12.085 (2/15/2018)

  • File loading times enhanced.

11.50 (3/22/2017)

  • User interface completely updated. Fonts are now 25% bigger. This is great for those using bigger monitors.

11.30 (12/16/2016)

11.10 (11/23/2016)

  • Installation was enhanced to allow for wrapping application within a service.

10.10 (2/16/2016)

  • Skip INPUT files already processed (i.e. Do not overwrite existing Output files)  implemented in the File\Options menu item. Any input file that has an associated output file that exists will not be processed when this feature is enabled. This is useful for processing the same folder repeatedly while not converting files that have already been done.


10.03 (12/14/2015)

  • During registration, the "Register Now" button sometimes did nothing.


10.00 (12/13/2015) from 4.58 (12/1/2015)

  • Addressed several application stability issues.
  • Critical update. Windows 10 Compatibility. Do not use Windows 10 with a version earlier than 10.00.
  • Windows 10 (and Windows 8.1) Compatibility modifications completed. Please upgrade if you haven't done so already. This version will be much more reliable on the latest operating systems.


4.56 (8/10/2015)

  • Added ability to preserve time stamp to output file. See the File\Options menu item


4.50 (3/2/2015)

  • Japanese help file added


4.41 (10/16/2014)

  • When adding the first conversion item, the user interface now selects the just added item in the 'Conversion Task List'. This allows for modifying the just added item with the Update button. Previously, a user would have to manually click the just added row to modify it. This is much more user friendly.


4.40 (9/9/2014)

  • Default JPEG quality was changed from 75 to 100%
  • Default DPI was changed from 100 to 200.
  • NOTE the changes above will result in higher quality images as well as larger output file sizes.


4.32 (8/21/2014)

  • Documentation updated to reflect recent enhancements
  • Languages folder has been moved to the %AppData%\Softinterface, Inc\ folder.


4.31 (8/11/2014)

  • Application default font set to Tahoma. In some instances of Windows 7 (perhaps 8.x) the default font "MS Sans Serif" was installed but not the smaller type fonts. This resulted in a user interface with text much too large.


4.30 (7/22/2014)

  • Application prevents user from writing to operating system protected folders
  • Application loads and exits faster now. Needless startup and shut down items removed.
  • User interface: The 'Conversion Task List' grid now auto-sizes the Input and Output file columns making it much easier to see everything.
  • User interface: The LOG displays much better now that the table autosizes allowing for the viewing of the error/warning.
  • User interface: CTRL-TAB and (SHIFT-CTRL-TAB) now works for tabbed items within dialog boxes.
  • If a 'Conversion Job' file (e.g. *.SII) has #OPEN.SII at the end of the filename then the 'conversion job' will only be opened for editing and not executed when chosen from Windows Explorer. For example a file named c:\MyJobs\WorkingOnThis#OPEN.SII  will open within the user interface when double clicked. Without the #OPEN.SII the 'Conversion Job' file will execute as before.
  • User interface: Adjusted user interface to handle Windows 7 64 bit default font size
  • User interface: When opening a conversion Job file, the default folder will initially be %AppData%\Softinterface, Inc\Convert PDF to Image\
  • Demonstration 'Conversion Job' files are now installed in  %AppData%\Softinterface, Inc\Convert PDF to Image\ folder.
  • Users can specify the following in the program and command line:






4.20  (6/5/2014)

  • Manual updated
  • Version number now shown when launching application.
  • Windows 8 Installation - Removed excess icons in the Start menu.


4.10 (11/18/2013)

  • Registration upgraded to handle Windows 8.


4.01  (10/24/2013)

  • If the program was closed while the size was maximized to the screen the software would not re-open.This was introduced in version 4.00.


4.00 (10/21/2013)

  • Installation upgraded to handle Windows 8 and Windows 7.


3.70 (7/25/2013)

  • Documentation/Help updated. Chrome now works properly for html web based help.


3.66 (5/30/2013)

  • Selecting the INPUT or OUTPUT folder. When the asterisk was used, the program would always start the selection at the root ("computer") instead of the path last chosen. This is now resolved allowing for quick file/folder selection.


3.60 (4/5/2013)

  • Command line: Added /E switch for the application to return an Exit Code/Error level.

The following ERRORLEVELs are possible:

3 = Missing or invalid command line arguments

2 = Error occurred during conversion

1 = Shareware expired

0 = Success

3.50 (12/8/2012)

  • Conversion Options: Length and Width now behave differently. If you specify one as zero, and the other as greater than zero, the one specified as zero will be sized in order to retain the aspect ratio. For example, if you specify a width of 100 and a height of 0, the height will be automatically adjusted to retain the aspect ratio.  If both Length and Width are specified as 0, the size of the image will be the same as the original within the PDF.  If length or width is specified as negative, it will be assigned the same as the original length or width respectively. This was done as in most cases the aspect ratio is desired to be retained.

3.40 (7/30/2012)

  • Conversion Items may now be moved within the 'Conversion Task List'. Select the CONVERSION menu item or the RIGHT MOUSE CLICK to open a pop-up menu item. Move UP, DOWN, FIRST, and LAST are now available. CTRL-U and CTRL-D also move a conversion item up and down respectively.
  • Users may now be asked to save the 'Conversion Job' file if they are exiting, loading an existing 'Conversion Job' file, or requesting to create a new 'Conversion Job'. If there is no 'conversion job' file at the time, there must be at least 2 conversion items in the 'Conversion job' to be asked to save. Users will not be asked to save if they've loaded a 'Conversion Job' and haven't modified it.

3.30 (5/21/2012)

  • Command Line: A time stamp will be put in the log file (if /L is specified).


3.10 (9/5/2011)

  • User Interface greatly enhanced.

     'Convert PDF to Image' new user interface

3.04 (3/1/2011)

  • COM interface ignores command line, and was using program user interface settings instead.


3.01 (8/14/2010)

  • Documentation updated


3.00 (8/16/2010)

  • Windows 7 compatibility enhancements made.  Default report folders now updated.


2.43 (12/16/2009)

  • Help system completely rewritten.  CHM help file now used, and web help is there for backup.
  • User Interface: The terms "Original" and "Target" file have been replaced with the more intuitive "Input" and "Output" respectively.
  • User Interface: If users launch the target file and it does not exist, now it opens the folder in explorer.

2.41 (10/27/2009)

  • User Interface: Upon completion of a Conversion Job, the status bar now flashes 100% complete.   If minimized, the taskbar flashes to indicate completion.
  • User Interface: When running the scheduler, if program is minimized the time remaining shows up in the task bar.
  • User Interface: When running the scheduler, PAUSE button now enabled to halt scheduler.

2.40 (8/19/2009)

  • The Shell Extender would open the file specified, however the user interface did not look proper.

2.39 (8/14/2009)

  • Move the input (original) file after processing has been added as a 'program option'. See the File\Options menu or the Advanced Options button in the user interface.  This will be very helpful for those looking to use the scheduler to convert a specific folder of files while avoiding redundant conversions.
  • Scheduler updated. Countries where time format was MM/DD/YYYY were sometimes problematic.

2.37 (6/12/2009)

  • Command Line: /O switch was broken.

2.36 (5/29/2009)

  • Command Line: Full path not required for /S /T /L /B and /J. If the full path is not specified it is assumed the current folder will be used. If the current folder path is invalid, then the folder that contains ConvertXLS.exe will be used. This makes it easy to specify the command line like so:

          ConvertPDFToImage.exe /S "Apples.pdf" /C1 /T "Apples Output.jpg"

2.35 (3/30/2009)

  • Usability: Most Recently Used Conversion Job files now available from the FILE menu item.

2.340 (3/30/2009)

  • Usability: Users no longer have to press the ADD button for the program to convert. Upon pressing the ADD button, the program assumes you will be creating a conversion job that has more than one conversion item.

  • Usability: When pressing the PAUSE button, the status bar now reflects this fact, and the Green check or Red X is properly displayed if the last running conversion job finished.

  • Usability: Users no longer have to press REWIND if the last run went to 100% completion.

  • Usability: When pressing the PAUSE button, the mouse now restores back to the arrow as it should.

  • Error Logging: If users pressed PAUSE during a conversion job, and then clicked CONVERT, any errors logged from this point had an incorrect 'Conversion Job Number'.

  • Command Line: Should run much faster now that many ini parameters are not being unnecessarily loaded.

2.32 to 2.332 (2/26/2009)

  • General. Loading the application should occur faster.

2.31 to 2.32 (8/15/2008)

  • Command Line, when no path was given and double quotes were used, an error would occur.

2.30 to 2.31 (2/21/2008)

2.21 to 2.30 (2/13/2008)

  • Loading a conversion job file now works properly.

  • Scheduler: Certain regional settings such as Greece, made the scheduler behave incorrectly.

2.20 to 2.21 (12/13/2007)

  • Conversion: Temporary files were not being deleted.

2.19 to 2.20 (10/29/2007)

  • Scheduler: When using international operating system, then restarting program sometimes caused an issue due to international dates.

2.18 to 2.19 (9/19/2007)

  • Conversion: PDF to multiple tiffs sometimes did not work, whereas pdf to single tiffs always seemed to work.

2.17 to 2.18 (9/18/2007)

  • Conversion: Picking the file and file target type now lead to a much easier default target file being displayed.  Target file is no longer all lower case, but, is based on how the original file is.

2.16 to 2.17 (7/30/2007)

  • Speed enhancements to overall program

2.15 to 2.16 (6/20/2007)

  • Window Vista: More compatibility issues resolved. Help file specifically addressed

2.14 to 2.15 (5/21/2007)

  • File Conversion: Multiple file output, now file names are formatted differently. From outputfile-1.jpg to outputfile-00001.jpg.

2.13 to 2.14 (5/21/2007)

  • Documentation updated. HTML-help and HLP file that is installed with the application.

2.02 to 2.13 (5/4/2007)

  • Conversion: PDF to TIFF, colors were not coming out properly

  • User interface greatly simplified.

2.01 to 2.02 (5/2/2007)

  • Registration: A small issue existed in countries where the decimal was a comma, not a period (i.e. France).

1.30 to 2.01 (5/1/2007)

  • Ability to select subfolders was hidden, this is now visible

1.20 to 1.30 (4/30/2007)

  • Delete file after processing was failing if the file had read only attributes. Read only attributes are now changed to read/write before deleting.

  • Target file button was being hidden whenever the original file was specified with the wildcard (*) asterisk.  Target file button is now always displayed.

1.10 to 1.20 (4/28/2007)

  • You can now launch BAT files from the "Launch (Run) Program" special process

  • File\Options menu item added

  • File\Options\ Delete original files after processing option added

  • File\Options\ Log file of files converted now optional

  • /Z switch added for Verbose Logging while doing command line.

1.09 to 1.10 (4/25/2007)

  • User Interface given a 'Face Lift'

  • Installation redone to fix several issues.

1.08 to 1.09 (4/15/2007)

  • Command Line no longer checks for file extension matching.  This resolves a command line issue in which the program incorrectly reported: "Conversion Job File (*.SII) specified in the command line (/J) does not exist." And "Missing required or invalid command line argument(s)".

1.07 to 1.08 (4/1/2007)

  • Minor fixes in User interface and image conversion

1.05 to 1.06 (3/20/2007)

  • User interface now updates file type for the original file automatically and also warns user if there is a mismatch before adding.

  • If a general failure occurs when converting more than one file, it continues to convert instead of stopping upon first failure.

1.04 to 1.05 (3/8/2007)

  • User interface (not command line): It is now impossible to enter a double quotation character (e.g. ") whenever specifying a file.

  • When loading a 'Conversion Job', it would not inform you that a target folder did not exist, and when trying to run this conversion job, it would report a General Failure.  Now, the directory will be created for you, and if it can't be, a proper error message will be reported.

1.04 to 1.05 (3/2/2007)

  •  Fixes issues with some images that do not have resolutions set within them (uses default resolution, Windows 9x shows this, Windows 2K/XP "assume" resolutions if there are none set)


1.02 to 1.03 (2/21/2007)

  •    Enhanced installation
