Interactive playgrounds

Nine hands-on environments that exercise the entire pdfnative ecosystem in your browser. No install, no API keys, no build step. Pick a card to dive in — every playground includes a switcher at the top so you can hop between them without coming back here.

Extreme scripts Library

Stress-test BiDi mixing across Arabic + Hebrew + Thai + Latin, Tamil ultra-conjuncts, Bengali & Devanagari with reph and multi-halant ligature chains, and isolated Arabic harakat. Edit the inputs and regenerate.

All 22 scripts + emoji Library

The flagship stress test: render every Unicode script pdfnative supports — 22 writing systems with BiDi and OpenType shaping — plus native COLRv1 colour emoji, all composited into a single PDF by one buildDocumentPDFBytes() call. The routing engine dispatches every code point to the right embedded font automatically.

PDF Toolkit Library 1.4.0 → 1.6.0

Outline bookmarks, page labels, viewer preferences, nested lists, cell borders, merge / split / extract — plus the 1.6.0 round trip: fill & flatten an encrypted AcroForm, re-encrypt a merged document (AES-256 password rotation), and extract text with positions. Each a one-click downloadable PDF.

Charts Library 1.6.0

New in 1.6.0: native vector charts — bar, horizontal-bar, line (with markers), pie, and donut — rendered as pure PDF path operators. Multi-series, legends, "nice" axis ticks, negative values, and tagged /Figure alt text. Each preset is a one-click downloadable PDF.

Authoring+ Library 1.5.0

Everything new in 1.5.0: SVG <text> labelled charts, the opt-in layout debug overlay (debug: true) plus inspectDocumentLayout(), and typed markup annotations with build + read-back — each a one-click downloadable PDF.

Medical 800-page Library

Generate a synthetic 800-page clinical report off the main thread using a Web Worker. Live progress bar, streaming output, optional Tagged PDF/A. The performance benchmark you can run yourself.

CLI builder CLI

Compose pdfnative-cli commands (render · sign · inspect · verify · merge · split · extract · annotate · govern) interactively. Live shell preview, validation rules, copy-to-clipboard, and ready presets covering every common workflow.

MCP tool explorer MCP

Browse the pdfnative-mcp v1.4.0 toolset (19 tools: incl. page-tree merge_pdfs, split_pdf, extract_pages, markup annotate_pdf, the network-free draft_governance_issue, plus validate_pdf, verify_pdf, add_attachment, extract_attachments), copy a ready-to-paste config snippet for Claude Desktop, Cursor, Continue, Zed (or any stdio MCP client), and generate the same PDFs an AI assistant would receive — directly in your browser.

React renderer React

Write JSX with pdfnative-react v1.0.0 and render a real PDF on-device — a custom React 19 reconciler compiles <Document>/<Table>/<Barcode> straight to pdfnative blocks, no SaaS round-trip. The demo loads React + the renderer from a CDN; the published package keeps the engine zero-dependency.

What about non-interactive examples?

The repository ships with 44 generator categories producing ~227 sample PDFs covering financial statements, multi-language documents, barcodes, SVG, watermarks, forms, encryption, signatures, streaming, parser, charts, and stress tests. Run npm run test:generate after cloning.
