In this step‑by‑step tutorial you’ll discover how to add redaction annotation to PDF using Java with a powerful, cross‑platform annotation library. Redaction annotations let you selectively hide or permanently remove sensitive information from a PDF document. Because the library is platform‑agnostic, the sample code runs flawlessly on any operating system. Follow the concise guide below to incorporate redaction annotation in PDF using Java.

Steps to Add Redaction Annotation to PDF using Java

1. Use Maven repository to install GroupDocs.Annotation for Java into your project for adding redaction annotation
2. Import the necessary classes for inserting redaction annotation
3. Instantiate an Annotator class object by passing the file path of the PDF to its constructor
4. Instantiate a ResourcesRedactionAnnotation class instance and specify the required properties, including the position, page number, and other relevant parameters
5. Call the Add method of the Annotator class, passing the ResourcesRedactionAnnotation object as an argument
6. Call the Annotator.save method to store the modified PDF to disk

The above-mentioned steps have been provided to help you seamlessly insert redaction annotation in PDF using Java. These instructions are compatible with popular operating systems like Windows, macOS, and Linux, as long as Java is installed. Additionally, there is no requirement for any extra software installation. Below is a code example that demonstrates the procedure for adding a redaction annotation to a PDF.
