Add PDF Redaction to WinForms Apps
Remove private information from PDF documents to help protect sensitive text and images when files are shared or archived.

PDF redaction permanently removes selected content from a document. In a WinForms application, developers can use it to remove customer details from invoices, conceal personal information in reports or prepare documents for external review. A redaction workflow can mark content for checking before applying the changes, giving users control over what is removed from the saved PDF.
Several PDF libraries support redaction in WinForms applications, including:
- DevExpress PDF Document API for .NET lets you find sensitive text, create redaction annotations and apply them to permanently remove the underlying content.
- Syncfusion .NET PDF Library provides redaction APIs for Windows Forms applications, including support for removing text from PDF documents.
- XFINIUM.PDF CROSS-PLATFORM BUNDLE supports text and image redaction, with redaction annotations for identifying content to remove.
