The Syncfusion .NET PDF library provides an easy way to permanently remove confidential or sensitive information from PDF documents with just a few lines of code. It complies fully with privacy laws such as GDPR (General Data Protection Regulation).
Mark sensitive or confidential data programmatically and forward it to the next person for further review and approval before redacting.
Remove sensitive or confidential text, images, areas, or entire pages entirely and permanently from the PDF documents using the PDF redaction support.
Programmatically search the entire document to identify a specific text and personal information. Then, automatically mark and redact sensitive information patterns related to phone numbers, credit cards, and email addresses.
Draw the overlay text on the redacted area and customize the overlay text with a different font, style, color, and brush.
Redact the information from a page by drawing an image on the redacted area. This will completely remove the content from the PDF document and apply the image over the redacted area.
