As my B-Tech Final Year Project is almost finished, now I can relax more and get back to blogging like before. Sorry for such a long gap. Now no more. CHEERS!!! :-D

Yesterday, I was stuck when my friend asked me about software to merge two or more PDF documents at one go. I knew many software but none were as fast as desired and also most of them were not free as well.

Recently, I found a tool that can easily merge, split and repair your PDF files at such a rapid pace that you wouldn’t believe it. Not only that you can also decrypt, encrypt and rotate your PDF files. With no installation needed, PDFTK (PDF Tool Kit) is a command-line tool for doing everyday things with PDF documents. It does not require Acrobat, and it runs on Windows, Linux, Mac OS X, FreeBSD and Solaris.

First download the tool from this location. After you have downloaded the software, unzip it to the location easily accessible from command prompt. In my case I have copied the file PDFTK to C: / and also all the required PDF files to the same location. Open a command prompt and type pdftk --help. You should get various usage instructions.

Pdftk can also be used for many other functions such as the following:-

  • Merge PDF Documents
  • Split PDF Pages into a New Document
  • Rotate PDF Pages or Documents
  • Decrypt Input as Necessary (Password Required)
  • Encrypt Output as Desired
  • Fill PDF Forms with FDF Data or XFDF Data and/or Flatten Forms
  • Apply a Background Watermark or a Foreground Stamp
  • Report on PDF Metrics such as Metadata, Bookmarks, and Page Labels
  • Update PDF Metadata
  • Attach Files to PDF Pages or the PDF Document
  • Unpack PDF Attachments
  • Burst a PDF Document into Single Pages
  • Uncompress and Re-Compress Page Streams
  • Repair Corrupted PDF (Where Possible)

Below are the different commands by which you can manipulate various PDF files. Open Command Prompt and go to the location where you have copied your pdftk file along with other pdf files. At that location perform the below mentioned commands to get the desired outputs.

Examples

Merge Two or More PDFs into a New Document

pdftk 1.pdf 2.pdf 3.pdf cat output 123.pdf

Split Select Pages from Multiple PDFs into a New Documentpdftk A=one.pdf B=two.pdf cat A1-7 B1-5 A8 output combined.pdf

Rotate the First Page of a PDF to 90 Degrees Clockwise

pdftk in.pdf cat 1E 2-end output out.pdf

Rotate an Entire PDF Document’s Pages to 180 Degrees

pdftk in.pdf cat 1-endS output out.pdf

Encrypt a PDF using 128-Bit Strength (the Default) and Withhold All Permissions (the Default)

pdftk mydoc.pdf output mydoc.128.pdf owner_pw foopass

Same as Above, Except a Password is Required to Open the PDF

pdftk mydoc.pdf output mydoc.128.pdf owner_pw foo user_pw baz

Same as Above, Except Printing is Allowed (after the PDF is Open)

pdftk mydoc.pdf output mydoc.128.pdf owner_pw foo user_pw baz allow printing

Decrypt a PDF

pdftk secured.pdf input_pw foopass output unsecured.pdf

Join Two Files, One of Which is Encrypted (the Output is Not Encrypted)

pdftk A=secured.pdf mydoc.pdf input_pw A=foopass cat output combined.pdf

Uncompress PDF Page Streams for Editing the PDF Code in a Text Editor

pdftk mydoc.pdf output mydoc.clear.pdf uncompress

Repair a PDF’s Corrupted XREF Table and Stream Lengths (If Possible)

pdftk broken.pdf output fixed.pdf

Burst a Single PDF Document into Single Pages and Report its Data to doc_data.txt

pdftk mydoc.pdf burst

Report on PDF Document Metadata, Bookmarks and Page Labels

pdftk mydoc.pdf dump_data output report.txt
