GroupDocs.Redaction for Java lets developers remove sensitive data from ‎popular file formats like Microsoft Word, Excel, PowerPoint, PDF and image. The redaction library offers a single ‎format-independent interface to redact any type of classified information including social security numbers, medical information, financial, proprietary, legal or even trade details through text, metadata ‎and annotation redaction types. It allows you to save the document in its original format and create a sanitized PDF document with raster images of original pages.
