PDF Redaction SDK

Redact PDFs with a secure, efficient PDF redaction library

Use our PDF redaction SDK to redact sensitive, confidential, and privileged information. Comply with GDPR and other privacy laws by permanently removing personally identifiable information (PII) from PDF documents.

How it works

Permanent data removal

Redaction in PDFs is a two-stage process.

step 1

Use the intuitive UI to select text, images, or patterns. Or, leverage the API to automatically identify sensitive data (e.g. credit cards, email addresses).

Step 2

Confirm and permanently remove the marked data from the document, ensuring it can never be recovered.

Customizable PDF redaction library for workflows

Manual redaction

Give users a hands-on approach to selecting and applying redactions with a clear, confirmation-based UI.

Semi-automated workflow

Utilize powerful search patterns and regex through the Search API to identify sensitive content with precision.

Fully automated batch redaction

Scale up redaction for large datasets using automation to handle high-volume documents effortlessly.

KEY FEATURES

  • UWP (Universal Windows Platform) — Integration capabilities for Windows applications, allowing redaction features within UWP app.
  • Android — Support for Android applications, enabling secure redaction on mobile devices.

Can the redaction user interface be customized to fit specific application requirements?

Yes. The SDK offers a customizable user interface, allowing developers to adjust colors, overlay text, and trigger specific workflows. This flexibility ensures the redaction tools can be tailored to align with the design and functionality requirements of the host application.

Is the redaction process performed client-side or server-side, and what are the implications for data security?

The SDK performs redaction operations directly in the browser on the client side, eliminating the need for server-side processing. This approach enhances data security by ensuring sensitive documents aren’t transmitted over networks or stored on external servers during the redaction process.

How does the SDK facilitate automated redaction processes?

Nutrient's SDK provides a robust API that enables automated redaction by searching for specific text strings, preset patterns (such as credit card numbers or email addresses), or custom regular expressions. This automation streamlines the redaction process, reducing manual effort and the potential for human error.

What types of content can be redacted using Nutrient's PDF redaction SDK?

The SDK allows for the permanent removal of various content types within PDF documents, including text, images, and vector graphics. This ensures sensitive information isn’t merely obscured, but rather completely eliminated from the document.
