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 -help

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 options

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]


Use switches -src and -dst to set source for input files and and output destination for converted files. You can also rotate document pages using -oper autorotate, -oper rotate; add a watermark using -oper textwatermark and -oper watermark switches. Use -options to set common parameters.

-srcThe source path to a file or files within a folder that should be converted. Can contain a search mask (to allow processing any files use *.*).
2PDF.exe -src "C:\Incoming\Overview.docx" -dst "C:\Output"
2PDF.exe -src "C:\Incoming\*.*" -dst "C:\Output"
If you have a list of files to convert, it should be saved as a text file. To set a list of files as a source, use @ before the file path.
2PDF.exe -src "@C:\Incoming\list.txt" -dst "C:\Output"
-dstThe destination folder for the output PDF file(s).
2PDF.exe -src "C:\Incoming\*.*" -dst "C:\Output"
-pdfSets PDF format options, such as multipage and OCR. 
-oper autorotateSets landscape or portrait orientation for output files. 
-oper rotateRotates document pages at a specific angle. 
-oper textwatermarkAdds a text watermark to document pages. 
-oper watermarkAdds an image watermark to document pages. 
-optionsSets up file processing and common 2PDF options.  
-aboutShows license key and software version.
2PDF.exe -about

Common options with parameters

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


(values in bold are set by default)
pages: Set page range.
Example: pages:1,3,5-12
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
overwrite:Overwrite existing files or skip them no, yes, skip
delsrc:Delete source filesno, yes
keep_outfile:Keep the output file in case of an error yes, no 
break_on_error:Break on error (stop the program in case of an error)no, yes
template:Add output file name template. By default, page counter appears only for multipage files split into pages.
{*SrcFilename} – source file name;
{*WorksheetName} – worksheet file name (for Excel and CAD files only);
{*SrcFileMPageNo} – source file page number;
{*DstFileExt} – destination file extension.
srcpwd:Input password for the source file or files (if they are password-protected). Example: srcpwd:123456
If the input folder contains several files secured with different passwords, you can specify them too, each attribute and value separated by space. Example: srcpwd:password1 srcpwd:password2 srcpwd:password3 (The order is not important).
Please note: this option unlocks secure files and removes the source files' password protection.
Enter password(s) for source file(s)
dstpwd:Input password for the destination file or files to password-protect them. This way, you can protect one or multiple files at once with a password. Only a single password can be used for each command.
Enter password for output file(s)
attachments: Set processing of file attachments. Can be saved separately, ignored or combined with the file itselfseparate, ignore, combine
sort:Sort output files. Can be sorted by different parameters like name, date, file type, and moreunsorted, name, date, type, size, path, name_d, date_d, type_d, size_d, path_d
silent:Suppress console output – do not show the conversion process and convert silentlyno, yes
alerts:Display alert windowsyes, 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:
Enter the number of source files


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.

PDF format parameters for converted files

You can control different parameters related to the PDF format using the -pdf switch.


AttributeDescriptionValue (values in bold are set by default)
