PDF is the most popular file format for saving documents. A new version of PDF standard is under development under the name ISO/CD 32000-2 - Document management—Portable document format—Part 2: PDF 2.0 (as of July 2011). PDF 2.0 was accepted by ISO as a new proposal in 2009 (ISO/NP 32000-2).

However, many PDF users are boring about how to replace or change text in thousand of PDF documents as below.

Q1: How can I edit pdf text without screwing up alignment?
I am trying to edit text in a pdf document of a chart but it continually throws the alignment of the text on the chart out of whack, moving things into the wrong fields or just in general out of position. Even when I am replacing existing text with the same amount of characters (say, changing 21.30 to 20.30) it throws everything off. How can I avoid this or fix it when it happens?

Q2: I need a Linux-based script to replace text in a PDF document on the fly?
I would like to serve customized PDF documents from templates. The templates contain tokens like {firstname} that would be replaced with actual data.
For resolving these problems, I search a tool--- PDF Text Replace in the website. PDF Text Replace can help you batch replace or change text in many PDF files automatically. You also can remove unwanted word from PDF files easily. Learn more about how to replace Text from PDF.
