PDF Dancer Redaction SDK
What PDF Dancer Redaction SDK is
PDF Dancer Redaction SDK identifies personally identifiable information in finished PDFs, routes lower-confidence findings for review, and permanently removes approved content with an audit trail. It accepts scanned, digital, and mixed PDFs, using OCR for scanned pages, images, and non-standard text layers. Its detection model considers document structure and context when identifying entities and assigning confidence scores. Redaction removes the underlying PDF content at the binary level rather than covering it with an overlay. The audit trail records each finding’s entity type, confidence score, page location, and review outcome. Python, Node.js, and Java SDK guides are available for backend pipelines and JVM services. Teams can use a hosted cloud API or deploy on premises to keep documents in their own environment. The published English-language benchmark reports email-address recall of 99.98%, precision of 99.58%, and an F1 score of 0.998. One limitation is that the engine analyzes pages independently and may miss an entity spanning pages. Cloud usage is billed at $0.20 per page and requires the $199/month Pro plan; enterprise on-premises pricing is custom. The v3 migration guide says there is no v3 SDK replacement for redaction.
