PDF-Zensor can be used to censor PDF-files. As such it strips annotations and metadata as well as textual and graphical content from the PDF-file. It can also partially censor PDF-files and highlight certain text phrases.
The application comes with a set of predefined colors, however, individual colors for censoring different elements can be configured as well.
PDF-Zensor uses a number of open source projects to work properly:
- PDFBox - The Apache PDFBox library is an open source Java tool for working with PDF documents.
- Picocli - Command line interface
- Log4J - Apache Log4j is a Java-based logging utility.
- Jackson - In computing, Jackson is a high-performance JSON processor for Java.
- Apache Commons - Apache Commons is an Apache project focused on all aspects of reusable Java components.
And of course PDF-Zensor itself is open source.
