Use PDFtk to add a "stamp" or a "background" to a PDF and restrict editing/copying.

pdfWatermarkEncrypt.bat

@echo off
if [%1]==[] goto :eof
:loop
pdftk %1 stamp back.pdf output "%~dpn1_new%~x1" owner_pw somepasswordyouwant
shift
if not [%1]==[] goto loop

To use this:

• Download and install PDFtk server.
• Copy the "pdftk.exe" and "libiconv2.dll" files from the installation directory into the same folder that you saved this batch file.
• Create a file named "back.pdf" to use as the background or stamp and save that in the same directory as this batch file.
• Drag files you want to protect onto pdfWatermarkEncrypt.bat and wait for the output to be produced.

The files would be named with the original name plus _new.

Hello.

If I code one file at a time using:

pdftk 610221-02-49-A-R4.pdf stamp EDITTANGGAL_STEMPEL.pdf output x.pdf
It worked

But when I tried the code above, no file was created.

Why?

Regards,
