composer require nextpdf/core
The PDF 2.0 engine,
native to PHP 8.4.
Build once. Render right. Trust every PDF. NextPDF generates ISO 32000-2 documents from HTML and CSS, signs them with PAdES, tags them for accessibility, and exposes an AI-ready MCP server — with an open-source core under Apache 2.0.
NextPDF Core
Free, open-source, and built to the spec
Everything below ships in NextPDF Core under Apache-2.0. Pro and Enterprise add commercial capabilities on top of the same engine.
PDF 2.0 generation
Native ISO 32000-2:2020 output — text, images, tables, vector graphics, and forms.
HTML to PDF
Render modern CSS — flexbox, gradients, and custom properties — straight to PDF.
PAdES signatures
Apply PAdES B-B digital signatures, with ICC v4 colour and a halftone subsystem.
Accessible by default
Emit PDF/UA-2 tagged structure so documents carry their semantics, not just pixels.
Ready for AI agents
An MCP server exposes deterministic PDF tools to AI systems over a typed contract.
Engineered for trust
Worker-safe architecture, strict types, and PHPStan Level 10 across the codebase.
Start with Core today.
Install the open-source engine with one Composer command, then upgrade to Pro or Enterprise when you need signatures at scale, compliance, or forensics.
