PDF Replacer is a program that allows PDF text replacement through a simple and straightforward interface.
One thing to note here, the PDF document needs to be unprotected to make the changes afforded by PDF Replacer.
With PDF Replacer, you can easily replace text in multiple PDF documents with new text. You can also modify the substituted text font with bold, italic, underline, and line-through if desired. PDF Replacer also permits you to replace the text in some PDF pages instead of the whole PDF document and provides you with a page range option to replace only your selected pages. PDF Replacer supports PDFs created in more than 50 languages.
