Edit/remove text/strings in/from PDF files/documents

I really need to get rid of "Word" in a pdf file I have. "Word" is just one word with no spaces and it appears on multiple pages in the document.

My solution: Convert the pdf to ps, then remove/replace Word in the plaintext ps file, then convert it back to pdf.

1. Get/install Ghostscript, Sed and Xpdf.
2. Create the file removeWordFromPDF.bat
   
   

   @echo off
   if [%1]==[] goto help
   goto START
   
   :START
   echo Converting %1
   rem converting pdf to ps
   pdftops %1 %1temp.ps
   echo sed
   rem removing COPY and other strings
   sed -e s/(Word)/()/ ^
    < %1temp.ps > %1tempNoWord.ps
   echo ps2pdf
   rem converting ps to pdf
   ps2pdf %1tempNoWord.ps %1NoWord.pdf
   exit
   
   :HELP
   echo There is no input pdf file for removing a COPY string

3. Note 1: If "Word" is part of a longer word, you will have to remove one or both of the parentheses in the sed line
4. Note 2: If there are Unicode letters in "Word", you will need to convert the pdf to ps and open it in a text editor to find out what their code is.
5. Either add ";C:\Program Files\Ghostscript\gs8.70\lib" (or whatever version, whatever location you have installed to) to "Path" (see below) or replace the pdf2ps/ps2pdf/sed commands in the script with full paths to the executables.

You can now drag&drop pdf files on the .bat file.
