Command Line Syntax and Examples

The 2PDF Command Line Syntax and Examples page shows the conversion settings that you can specify to adjust your file conversion with 2PDF. The command line syntax parameters determine how files are converted as well as the structure and features of resultant PDF documents. 

Quick start

1. Press Win+R on your keyboard, type cmd and click OK to open the Command Prompt (CMD).

   

2. To call 2PDF, type in 2PDF.exe and press Enter. You can get an entire list of available operations and options by using this command line:

   2PDF.exe

3. The command lines have arguments with values, which are typed after the command itself. In general, the basic syntax is as follows:

   2PDF.exe -src "C:\In\*.*" -dst "C:\Out"

   • -src should be followed by the source folder path with files to be converted or path to input file; 
   • Asterisk (star, *) is a wildcard character which stands for any string of characters (or no characters at all). *.* stands for any filename – point – any file extension;
   • -dst should be followed by the destination folder path for output files;
   • When specifying the source folder path (or source file) and destination path (output folder) – enclose them in double quotation marks. Example: -src "C:\Incoming files\For conversion\Invoice.docx".
4. Press Enter to execute the command.
   

Command line structure

The basic command line structure sets the source for files and the destination path. After them you can add optional parameters for output PDF files such as file structure, handling attachments, page autorotation, and more. 

2PDF command line structure looks like:

2PDF.exe -<switch1> [param1:value paramN:value] -<switchN> [parameters]

Switches

Use switches -src and -dst to set source for input files and output destination for converted files. You can also: 

• Rotate document pages using -oper autorotate, -oper rotate switches; 
• Add a watermark using -oper textwatermark or -oper watermark switches; 
• Move, copy, or delete source files with -postproc switch;
• Set common parameters with -options and -pdf switches.

Switch	Description
-src	Sets a location of files that should be converted. Type of source Example Folder path -src "C:\In\*.*" Path to a file -src "C:\In\Document.docx" Path to a list of file destinations -src "@C:\Files\list.txt" Web address (URL) -src https://www.website.com Path to a list in Excel file (XLS, XLSX, CSV) -src "@C:\In\List.csv" Folder path must contain a search mask (to allow processing any files use *.*); If you have a list of files to convert, it should be saved as a text file or an Excel spreadsheet. To set a list of files as a source, use @ before the file path. Example: 2PDF.exe -src "@C:\In\List.txt" -dst "C:\Output" When setting the source folder path (or source file path) – don't forget to enclose them in double quotation marks. Example: 2PDF.exe -src "C:\In\Invoice.docx"; When using a web address (URL) as a source, you can add user and password if they are required to access the website.
-dst	Sets the destination folder for the output PDF file(s). Example: -dst "C:\Output"
-options	Sets up file processing and common 2PDF options.
-pdf	Sets PDF format options, such as multipage or OCR.
-oper autorotate	Sets landscape or portrait orientation for output files.
-oper crop	Performs page cropping.
-oper rotate	Rotates document pages at a specific angle.
-oper rasterize	Optimizes file size of a PDF by rasterizing its pages into JPEG format.
-oper textwatermark	Adds a text watermark to document pages.
-oper textannotation	Quickly adds text to document pages.
-oper watermark	Adds an image watermark to document pages.
-oper paint	Draws a rectangular border inside or around the output pages.
-oper removeblankpages	Removes unnecessary blank pages automatically.
-postproc	Performs additional post-processing actions: copy, move, or delete source or output files
-fls	Defines file loading settings.
-inipath	Set path and apply previously saved 2PDF Settings.
-info	Displays file information, such as the page counter of a source file.
-about	Shows license key and software version. Example: 2PDF.exe -about

OR

-cmdlines

Allows to run 2PDF command(s) from a TXT file. This can be helpful when the command is very long or if you want to run several commands sequentially. Example: 2PDF.exe -cmdlines "C:\Scripts\Command.txt"

Common options (-options)

General file conversion options are controlled by the -options switch. Values that are marked bold below are set by default.

-options

Parameter	Description	Value (values in bold are set by default)
pages:	Set page range. Example: -options pages:1,3,5-12	all
scansf:	Convert files within subfolders too (if you specify a folder as a source)	yes, no
keepsf:	Keep the same subfolder structure as in the input folder (if you specify a folder as a source)	yes, no
mswildc:	Enable/disable Microsoft DOS/Win32 wildcard matching algorithm. Learn more [+] This algorithm is a bit different from the "expected" behavior, since some wildcards work in a different way in Windows (compared to Linux, for example). Suppose, you want to convert DOC files only. It would seem that you should just use this command: 2PDF.exe -src "C:\In\*.doc" But as a result, both .DOC and .DOCX files will be converted, which is not needed. To convert only files that match the specified file extension, disable the Microsoft wildcard matching algorithm. To do that, use the command: 2PDF.exe -src "C:\In\*.doc" -options mswildc:no	yes, no
overwrite:	Overwrite existing files or skip them	no, yes, skip
ocf:	Overwrite options for combined PDF/TIFF files if files with the same filename already exist in the output folder (they may have been created before the current 2PDF session).  Compared to overwrite: parameter, this one works only if -pdf multipage:append or multipage:prepend is used to create multipage documents. append – adds new files as pages to the end; createseparate – creates separate files using File (1), File (2), … pattern; overwrite – overwrites existing files with new ones; skip – does not perform conversion and logs the event only. Example: 2PDF.exe -src "C:\In\*.*" -dst "C:\Out" -pdf multipage:append -options ocf:createseparate	append, createseparate, overwrite, skip
break_on_error:	Break on error (stop the program in case of an error)	no, yes
template:	Adjust output file name template. You can enter your own file name and/or use macros: {*SrcFilename} – source file name; {*WorksheetName} – worksheet file name (for Excel and CAD files only); {*SrcFileMPageNo} – source file page number; {*DstFileExt} – destination file extension. By default, the page counter ({*SrcFileMPageNo}) appears only for multipage files split into pages. Example: -options template:"Document-{*SrcFileMPageNo}.{*DstFileExt}"	{*SrcFilename}{*WorksheetName}{*SrcFileMPageNo}.{*DstFileExt}
srcpwd:	Input password for the source file or files (if they are password-protected). Example: -options srcpwd:123456 If a password contains spaces, input it between double quotation marks. Example: -options srcpwd:"my password" If you have files secured with more than one password, you can enter multiple passwords too (the order is not important). Example: -options srcpwd:password1 srcpwd:password2 srcpwd:password3	Enter password(s) for source file(s)
dstpwd:	Set password to create password-protect output PDF files. This way, you can protect one or multiple files at once with a single password. Only a single password can be used within a command. Example: -options dstpwd:123456	Enter password for output file(s)
res:	Change rasterization resolution (DPI) of the output files. This parameter may need changing only when the OCR feature is used which results in file's rasterization. The default value is 300 which is good for most scenarios, but you can change it for your needs. The rasterization resolution can be set within the range of 72-4096.	300
attachments:	Set processing of file attachments. Attachments can be saved separately, ignored or combined with the file (append or prepend). Besides, you can convert attachments only, without the file(s).	ignore, separate, onlyatt, combine, combine_prepend
sort:	Sort output files. Can be sorted by different parameters like name, date, file type, and more. To sort the files in descending order, use values ending with _d (name_d, date_d, etc.).	unsorted, name, date, type, size, path, name_d, date_d, type_d, size_d, path_d
log:	Create events log. This parameter saves log files (in XML format) containing information about the system and records of all 2PDF events. We recommend having this parameter activated because information contained in log files will help our developers quickly identify what's happening in case of any error or issue. Example: -options log:no	yes, no
logpath:	Set path to log files location for the log: parameter. By default, it is %TEMP% which usually opens the path "C:\Users\[User]\AppData\Local\Temp". Example: -options log:yes logpath:"E:\2PDF Logs"	%TEMP%
reslog:	Create a resulting log file in TXT format with brief information about each session. Example: -options reslog:"C:\My folder\My_log.txt"
silent:	Suppress console output – do not show the conversion process and convert silently	no, yes
alerts:	Display alert windows	yes, no
fast_combine:	Set the number of files to quickly create a multipage PDF from them. Greatly increases file processing speed. Works with PDFs as source files only. The number of files is unlimited. Example: -options fast_combine:10000	Enter the number of source files
user:	Enter username (login) for converting a web page – when URL is set as a source and if password entry is required to access the web page. Don't forget to specify both credentials – user and password.	Enter username (login)
password:	Enter password if password entry is required to access the web page you want to print (URL is set as a source). Don't forget to specify both credentials – user and password.	Enter password

Example:

2PDF.exe -src "C:\In\*.*" -dst "C:\Out" -pdf multipage:split -options pages:"1,3,5-10" scansf:yes keepsf:no overwrite:yes template:"{*SrcFilename}{*SrcFileMPageNo}.{*DstFileExt}" sort:name attachments:combine dstpwd:123456 delsrc:yes silent:yes

In this example we also use -pdf multipage: split described in further section so that template:"{*SrcFilename}{*SrcFileMPageNo}.{*DstFileExt}" could take effect.

The -inipath switch enables you to load previously saved custom 2PDF Settings. These settings are saved using the Export button as a "2PDF-settings <date>.ini" file. By including the path to this settings file, you can apply specific default settings to your 2PDF command if needed.

Example:

2PDF.exe -src "C:\In\*.*" -dst "C:\Out" -inipath "C:\In\2PDF-settings 2023-12-25.ini"

Information (-info)

pagecount:

Get the number of pages of a file as executable's exit code. This command generates a code with the number of pages contained in a single file as executable's exit code. For example, Page count=5.

Example:

2PDF.exe -src "C:\In\Text.pdf" -info pagecount

Command lines (-cmdlines)

The -cmdlines switch allows you to set the path to a TXT file that contains the command (or multiple commands) that need to be executed. This can be helpful when the command is very long or if you want to run several commands sequentially.

2PDF.exe -cmdlines "C:\Folder\commands.txt"

Default settings (-ini)

The default settings are available in the editor with GUI controls. To access it, use this command:

2PDF.exe -ini

The Default Settings define the settings values for each 2PDF session (unless other values are specified in the command line which will override them). So you can set up everything only once, and they will be applied every time you use 2PDF. If you are not sure about a specific setting, please contact our support for assistance.
