GroupDocs.Redaction
What GroupDocs.Redaction is
GroupDocs.Redaction is a document library for finding and hiding or removing private information in business files, including PDFs, Office documents and images. It can search for sensitive text using case-sensitive or case-insensitive phrases and regular expressions, conceal whole or partial images, and remove or replace metadata such as Word author details and image EXIF data. The product lists more than 30 file formats, including PDF, DOC, DOCX, PPT, PPTX, XLS, XLSX and images, along with .NET, Java and Python editions. Automated, batch and OCR redaction are listed capabilities. GroupDocs says the library does not need external software such as Adobe Acrobat or Microsoft Office to manipulate documents. Deployment is on-premises; the company says files run on customers’ own machines, infrastructure and network rather than being sent back for processing. A browser-based redaction app is also available. Evaluation mode adds trial badges and limits output to the first three pages; a 30-day temporary license is available for unrestricted testing. Developer Small Business costs $1,199, paid once. Other license types have different listed terms.
