 OPTIONS
      A summary of options is included below.

      --help, -h
           Show this summary of options.

      <input PDF files | - |
           A list of the input PDF files. If you plan to combine these PDFs
           (without using handles) then list files in the order you want
           them combined.  Use - to pass a single PDF into pdftk via stdin.
           Input files can be associated with handles, where a handle is one
           or more upper-case letters:

           <input PDF handle>=<input PDF filename>

           Handles are often omitted.  They are useful when specifying PDF
           passwords or page ranges, later.

           For example: A=input1.pdf QT=input2.pdf M=input3.pdf

      [input_pw <input PDF owner passwords |
           Input PDF owner passwords, if necessary, are associated with
           files by using their handles:

           <input PDF handle>=<input PDF file owner password>

           If handles are not given, then passwords are associated with
           input files by order.

           Most pdftk features require that encrypted input PDF are
           accompanied by the ~owner~ password. If the input PDF has no
           owner password, then the user password must be given, instead.
           If the input PDF has no passwords, then no password should be
           given.

           When running in do_ask mode, pdftk will prompt you for a password
           if the supplied password is incorrect or none was given.

      [<operation> <operation arguments>]
           Available operations are: cat, shuffle, burst, rotate,
           generate_fdf, fill_form, background, multibackground, stamp,
           multistamp, dump_data, dump_data_utf8, dump_data_fields,
           dump_data_fields_utf8, dump_data_annots, update_info,
           update_info_utf8, attach_files, unpack_files. Some operations
           takes additional arguments, described below.

           If this optional argument is omitted, then pdftk runs in 'filter'
           mode.  Filter mode takes only one PDF input and creates a new PDF
           after applying all of the output options, like encryption and
           compression.

         cat [<page ranges>]
              Assembles (catenates) pages from input PDFs to create a new
              PDF. Use cat to merge PDF pages or to split PDF pages from
              documents. You can also use it to rotate PDF pages. Page order
              in the new PDF is specified by the order of the given page
              ranges. Page ranges are described like this:

              <input PDF handle>[<begin page number>[-<end page
              number>[<qualifier>]]][<page rotation>]

              Where the handle identifies one of the input PDF files, and
              the beginning and ending page numbers are one-based references
              to pages in the PDF file.  The qualifier can be even or odd,
              and the page rotation can be north, south, east, west, left,
              right, or down.

              If a PDF handle is given but no pages are specified, then the
              entire PDF is used. If no pages are specified for any of the
              input PDFs, then the input PDFs' bookmarks are also merged and
              included in the output.

              If the handle is omitted from the page range, then the pages
              are taken from the first input PDF.

              The even qualifier causes pdftk to use only the even-numbered
              PDF pages, so 1-6even yields pages 2, 4 and 6 in that order.
              6-1even yields pages 6, 4 and 2 in that order.

              The odd qualifier works similarly to the even.

              The page rotation setting can cause pdftk to rotate pages and
              documents.  Each option sets the page rotation as follows (in
              degrees): north: 0, east: 90, south: 180, west: 270, left:
              -90, right: +90, down: +180. left, right, and down make
              relative adjustments to a page's rotation.

              If no arguments are passed to cat, then pdftk combines all
              input PDFs in the order they were given to create the output.

              NOTES:
              * <end page number> may be less than <begin page number>.
              * The keyword end may be used to reference the final page of a
              document instead of a page number.
              * Reference a single page by omitting the ending page number.
              * The handle may be used alone to represent the entire PDF
              document, e.g., B1-end is the same as B.
              * You can reference page numbers in reverse order by prefixing
              them with the letter r. For example, page r1 is the last page
              of the document, r2 is the next-to-last page of the document,
              and rend is the first page of the document. You can use this
              prefix in ranges, too, for example r3-r1 is the last three

              pages of a PDF.

              Page Range Examples without Handles:
              1-endeast - rotate entire document 90 degrees
              5 11 20 - take single pages from input PDF
              5-25oddwest - take odd pages in range, rotate 90 degrees
              6-1 - reverse pages in range from input PDF

              Page Range Examples Using Handles:
              Say A=in1.pdf B=in2.pdf, then:
              A1-21 - take range from in1.pdf
              Bend-1odd - take all odd pages from in2.pdf in reverse order
              A72 - take a single page from in1.pdf
              A1-21 Beven A72 - assemble pages from both in1.pdf and in2.pdf
              Awest - rotate entire in1.pdf document 90 degrees
              B - use all of in2.pdf
              A2-30evenleft - take the even pages from the range, remove 90
              degrees from each page's rotation
              A A - catenate in1.pdf with in1.pdf
              Aevenwest Aoddeast - apply rotations to even pages, odd pages
              from in1.pdf
              Awest Bwest Bdown - catenate rotated documents

         shuffle [<page ranges>]
              Collates pages from input PDFs to create a new PDF.  Works
              like the cat operation except that it takes one page at a time
              from each page range to assemble the output PDF.  If one range
              runs out of pages, it continues with the remaining ranges.
              Ranges can use all of the features described above for cat,
              like reverse page ranges, multiple ranges from a single PDF,
              and page rotation.  This feature was designed to help collate
              PDF pages after scanning paper documents.

         burst
              Splits a single input PDF document into individual pages. Also
              creates a report named doc_data.txt which is the same as the
              output from dump_data.  If the output section is omitted, then
              PDF pages are named: pg_%04d.pdf, e.g.: pg_0001.pdf,
              pg_0002.pdf, etc.  To name these pages yourself, supply a
              printf-styled format string via the output section.  For
              example, if you want pages named: page_01.pdf, page_02.pdf,
              etc., pass output page_%02d.pdf to pdftk.  Encryption can be
              applied to the output by appending output options such as
              owner_pw, e.g.:

              pdftk in.pdf burst owner_pw foopass

         rotate [<page ranges>]
              Takes a single input PDF and rotates just the specified pages.
              All other pages remain unchanged.  The page order remains
              unchaged.  Specify the pages to rotate using the same notation

                                July 24, 2013



              as you would with cat, except you omit the pages that you
              aren't rotating:

              [<begin page number>[-<end page number>[<qualifier>]]][<page
              rotation>]

              The qualifier can be even or odd, and the page rotation can be
              north, south, east, west, left, right, or down.

              Each option sets the page rotation as follows (in degrees):
              north: 0, east: 90, south: 180, west: 270, left: -90, right:
              +90, down: +180. left, right, and down make relative
              adjustments to a page's rotation.

              The given order of the pages doesn't change the page order in
              the output.

         generate_fdf
              Reads a single input PDF file and generates an FDF file
              suitable for fill_form out of it to the given output filename
              or (if no output is given) to stdout.  Does not create a new
              PDF.

         fill_form <FDF data filename | XFDF
              Fills the single input PDF's form fields with the data from an
              FDF file, XFDF file or stdin. Enter the data filename after
              fill_form, or use - to pass the data via stdin, like so:

              pdftk form.pdf fill_form data.fdf output form.filled.pdf

              If the input FDF file includes Rich Text formatted data in
              addition to plain text, then the Rich Text data is packed into
              the form fields as well as the plain text.  Pdftk also sets a
              flag that cues Reader/Acrobat to generate new field
              appearances based on the Rich Text data.  So when the user
              opens the PDF, the viewer will create the Rich Text appearance
              on the spot.  If the user's PDF viewer does not support Rich
              Text, then the user will see the plain text data instead.  If
              you flatten this form before Acrobat has a chance to create
              (and save) new field appearances, then the plain text field
              data is what you'll see.

              Also see the flatten and need_appearances options.

         background <background PDF filename | -
              Applies a PDF watermark to the background of a single input
              PDF.  Pass the background PDF's filename after background like
              so:

              pdftk in.pdf background back.pdf output out.pdf

                                July 24, 2013



              Pdftk uses only the first page from the background PDF and
              applies it to every page of the input PDF.  This page is
              scaled and rotated as needed to fit the input page.  You can
              use - to pass a background PDF into pdftk via stdin.

              If the input PDF does not have a transparent background (such
              as a PDF created from page scans) then the resulting
              background won't be visible -- use the stamp operation
              instead.

         multibackground <background PDF filename | -
              Same as the background operation, but applies each page of the
              background PDF to the corresponding page of the input PDF.  If
              the input PDF has more pages than the stamp PDF, then the
              final stamp page is repeated across these remaining pages in
              the input PDF.

         stamp <stamp PDF filename | -
              This behaves just like the background operation except it
              overlays the stamp PDF page on top of the input PDF document's
              pages.  This works best if the stamp PDF page has a
              transparent background.

         multistamp <stamp PDF filename | -
              Same as the stamp operation, but applies each page of the
              background PDF to the corresponding page of the input PDF.  If
              the input PDF has more pages than the stamp PDF, then the
              final stamp page is repeated across these remaining pages in
              the input PDF.

         dump_data
              Reads a single input PDF file and reports its metadata,
              bookmarks (a/k/a outlines), page metrics (media, rotation and
              labels), data embedded by STAMPtk (see STAMPtk's embed option)
              and other data to the given output filename or (if no output
              is given) to stdout.  Non-ASCII characters are encoded as XML
              numerical entities.  Does not create a new PDF.

         dump_data_utf8
              Same as dump_data excepct that the output is encoded as UTF-8.

         dump_data_fields
              Reads a single input PDF file and reports form field
              statistics to the given output filename or (if no output is
              given) to stdout. Non-ASCII characters are encoded as XML
              numerical entities. Does not create a new PDF.

         dump_data_fields_utf8
              Same as dump_data_fields excepct that the output is encoded as
              UTF-8.

         dump_data_annots
              This operation currently reports only link annotations.  Reads
              a single input PDF file and reports annotation information to
              the given output filename or (if no output is given) to
              stdout. Non-ASCII characters are encoded as XML numerical
              entities. Does not create a new PDF.

         update_info <info data filename | -
              Changes the bookmarks and metadata in a single PDF's Info
              dictionary to match the input data file. The input data file
              uses the same syntax as the output from dump_data. Non-ASCII
              characters should be encoded as XML numerical entities.

              This operation does not change the metadata stored in the
              PDF's XMP stream, if it has one. (For this reason you should
              include a ModDate entry in your updated info with a current
              date/timestamp, format: D:YYYYMMDDHHmmSS, e.g. D:201307241346
              -- omitted data after YYYY revert to default values.)

              For example:

              pdftk in.pdf update_info in.info output out.pdf

         update_info_utf8 <info data filename | -
              Same as update_info except that the input is encoded as UTF-8.

         attach_files <attachment filenames | PROMPT> [to_page
              Packs arbitrary files into a PDF using PDF's file attachment
              features. More than one attachment may be listed after
              attach_files. Attachments are added at the document level
              unless the optional to_page option is given, in which case the
              files are attached to the given page number (the first page is

              pdftk in.pdf attach_files table1.html table2.html to_page 6
              output out.pdf

         unpack_files
              Copies all of the attachments from the input PDF into the
              current folder or to an output directory given after output.
              For example:

              pdftk report.pdf unpack_files output ~/atts/

              or, interactively:

              pdftk report.pdf unpack_files output PROMPT

      [output <output filename | - |
           The output PDF filename may not be set to the name of an input
           filename. Use - to output to stdout.  When using the dump_data

           operation, use output to set the name of the output data file.
           When using the unpack_files operation, use output to set the name
           of an output directory.  When using the burst operation, you can
           use output to control the resulting PDF page filenames (described
           above).

      [encrypt_40bit | encrypt_128bit]
           If an output PDF user or owner password is given, output PDF
           encryption strength defaults to 128 bits.  This can be overridden
           by specifying encrypt_40bit.

      [allow <permissions>]
           Permissions are applied to the output PDF only if an encryption
           strength is specified or an owner or user password is given.  If
           permissions are not specified, they default to 'none,' which
           means all of the following features are disabled.

           The permissions section may include one or more of the following
           features:

      [owner_pw <owner password | PROMPT>]

      [user_pw <user password | PROMPT>]
           If an encryption strength is given but no passwords are supplied,
           then the owner and user passwords remain empty, which means that
           the resulting PDF may be opened and its security parameters

           altered by anybody.

      [compress | uncompress]
           These are only useful when you want to edit PDF code in a text
           editor like vim or emacs.  Remove PDF page stream compression by
           applying the uncompress filter. Use the compress filter to
           restore compression.

      [flatten]
           Use this option to merge an input PDF's interactive form fields
           (and their data) with the PDF's pages. Only one input PDF may be
           given. Sometimes used with the fill_form operation.

      [need_appearances]
           Sets a flag that cues Reader/Acrobat to generate new field
           appearances based on the form field values.  Use this when
           filling a form with non-ASCII text to ensure the best
           presentation in Adobe Reader or Acrobat.  It won't work when
           combined with the flatten option.

      [keep_first_id | keep_final_id]
           When combining pages from multiple PDFs, use one of these options
           to copy the document ID from either the first or final input
           document into the new output PDF. Otherwise pdftk creates a new
           document ID for the output PDF. When no operation is given, pdftk
           always uses the ID from the (single) input PDF.

      [drop_xfa]
           If your input PDF is a form created using Acrobat 7 or Adobe
           Designer, then it probably has XFA data.  Filling such a form
           using pdftk yields a PDF with data that fails to display in
           Acrobat 7 (and 6?).  The workaround solution is to remove the
           form's XFA data, either before you fill the form using pdftk or
           at the time you fill the form. Using this option causes pdftk to
           omit the XFA data from the output PDF form.

           This option is only useful when running pdftk on a single input
           PDF.  When assembling a PDF from multiple inputs using pdftk, any
           XFA data in the input is automatically omitted.

      [drop_xmp]
           Many PDFs store document metadata using both an Info dictionary
           (old school) and an XMP stream (new school).  Pdftk's update_info
           operation can update the Info dictionary, but not the XMP stream.
           The proper remedy for this is to include a ModDate entry in your
           updated info with a current date/timestamp. The date/timestamp
           format is: D:YYYYMMDDHHmmSS, e.g. D:201307241346 -- omitted data
           after YYYY revert to default values. This newer ModDate should
           cue PDF viewers that the Info metadata is more current than the
           XMP data.

           Alternatively, you might prefer to remove the XMP stream from the
           PDF altogether -- that's what this option does.  Note that
           objects inside the PDF might have their own, separate XMP
           metadata streams, and that drop_xmp does not remove those.  It
           only removes the PDF's document-level XMP stream.

      [verbose]
           By default, pdftk runs quietly. Append verbose to the end and it
           will speak up.

      [dont_ask | do_ask]
           Depending on the compile-time settings (see ASK_ABOUT_WARNINGS),
           pdftk might prompt you for further input when it encounters a
           problem, such as a bad password. Override this default behavior
           by adding dont_ask (so pdftk won't ask you what to do) or do_ask
           (so pdftk will ask you what to do).

           When running in dont_ask mode, pdftk will over-write files with
           its output without notice.
