Search & Replace PDF Text or Images in Javascript
Sample Javascript code to use PDFTron SDK for searching and replacing text strings and images inside existing PDF files (e.g. business cards and other PDF templates). Unlike PDF forms, the ContentReplacer works on actual PDF content and is not limited to static rectangular annotation regions. Learn more about our PDF Editing & Manipulation Library.
