Premium edition

Core vs Pro vs Enterprise

At a glance

NextPDF ships in three editions. The open-source core is a complete, production-grade Portable Document Format (PDF) 2.0 engine. NextPDF Pro and NextPDF Enterprise build on that foundation. Editions are cumulative: NextPDF Pro includes everything in the open core, and NextPDF Enterprise includes everything in NextPDF Pro.

The matrix compares editions by the value each capability gives you, not by its implementation. Each row names a capability, summarizes the benefit, and marks the lowest edition that includes it. For the standards behind these capabilities, see Compliance and conformance.

Editions explained

Open-source core. A complete PDF 2.0 engine for generating modern, standards-based documents. It is free and open, and it forms the foundation for every commercial edition. To compare the open distributions with a commercial edition, see Choose your path.
NextPDF Pro. The mid-tier commercial edition. It adds advanced generation, document operations, specialty barcodes, signing workflows (remote, cloud-KMS, sequential) on top of the Core baseline, and privacy tooling for teams that build document-heavy products.
NextPDF Enterprise. The upper-tier commercial edition. It includes everything in NextPDF Pro, plus long-term archival signing, hardware key custody, compliance and archival assurance, forensics, intelligence, and operational tooling for regulated and high-scale deployments.

Editions are cumulative and selected by license. Premium is the collective name for the two commercial editions, Pro and Enterprise. The signed license you activate determines which capabilities run. Evaluation output carries a watermark; a paid license removes it without application code changes. See Licensing and activation for the full flow.
