.NET PDF Redaction Library

Remove sensitive and personal data from your PDF documents.

Integrate PDF Redaction features in your workflows to safely share or archive your files.

Security and privacy

Redaction is the process of permanently removing visible text and other graphic elements from a PDF document. What has been removed is destroyed and not simply hidden as redaction marks are not annotations.

Easy process

Redacting a document with GdPicture.NET is simple and straightforward:

1. Add one or several redaction marks
2. Apply all redactions
3. Clear redactions if necessary

Customizable UX/UI

Redaction marks don’t have to be all black; sometimes, you still need to know what type of information has been erased.

If you need to remove data of different nature, you can modify the appearance of the marks by choosing a specific color for each type of content. You can also add a title and a comment to ease collaborative work and add clarity to your document.

GDPR compliance

Companies need to protect sensitive data within their organization of course, but they also have the duty to protect personal data from their customers and employees.
Laws and regulations like GDPR in Europe and the California Privacy Act in the US are protecting personal and sensitive data and have made redaction features a requirement for all companies.
