Java PDF SDK

Edit PDF Text in Java — No Scrambled Characters, No Broken Layout

Enterprise-ready Java SDK that truly modifies text in place. Find-and-replace with automatic reflow, HIPAA-compliant redaction, fill templates programmatically. No flattening. No image overlays. Precise text editing.

PDFDancer treats PDFs like editable documents. Select content by what it says — not where it sits on the page — then modify it. The PDF handles the rest.

Built for How Developers Actually Work with PDFs

In-Place Text Editing

Text is modified directly inside the PDF structure. No overlays, no image layers, no document rebuilds. The edited PDF is indistinguishable from the original.

Compliance-Grade Redaction

Content is permanently deleted from the PDF — not hidden behind an overlay. Every redaction is logged with timestamps and entity types for audit trails.

Thread-Safe for Scale

Each PDF session is independent and thread-safe. Spawn multiple threads, each with its own session. Process thousands of documents in parallel without corruption.

Spring Boot Native

REST controllers, @Value injection, service patterns — all out of the box. Maven or Gradle. Works with Spring Boot, Quarkus, Micronaut, and plain Java.

True content removal, not overlays. When PDFDancer redacts text, the original content is permanently deleted from the PDF — nothing can be recovered. This is the standard courts require.
