Professional Word document editing powered by WebAssembly. The Document Authoring SDK lets you edit DOCX files directly in the browser with full formatting support — tables, images, headers, and more. Export to PDF or DOCX without servers. TypeScript-first with complete data privacy.
DOCUMENT AUTHORING SDK DEMO
Use the interactive canvas below to experience professional DOCX editing as it would appear in your web app. Not a basic rich text editor — full page-based layout with tables, headers, rulers, and text-wrapped images. Import your Word documents to test formatting preservation. Everything runs client-side in your browser.
WebAssembly runs in-browser. No backend, no uploads, no server costs. Process documents offline or behind firewalls. GDPR and HIPAA compliance simplified.
Page-based layout engine mirrors Word. Tables, images, lists, headers, and footers render identically across browsers. PDFs match the screen exactly.
Full type safety and IntelliSense. DocJSON (versioned JSON) enables programmatic generation and template merging. React, Vue, or vanilla JS.
Keyboard shortcuts users know. Smooth scrolling. Interactive rulers. If they've used Word or Google Docs, they're productive immediately.
Generate invoices, contracts, or reports as JSON. Load instantly. Template documents, merge API data, build custom workflows. Type-safe with real-time rendering.
React, Vue, Svelte, Angular, or vanilla JS. Available via npm, CDN, or self-hosted. Full TypeScript support included.
Integration guides for every framework. Clone working samples. API docs with live examples. Support responds in hours. Production in hours, not weeks.

Yes. Runs entirely client-side with WebAssembly. Import Word docs, apply formatting, export PDFs or DOCX — no server needed. Works offline when self-hosted. Documents never leave the device.
PDF export and DocJSON (JSON format) built-in. DOCX import/export requires optional DOCX Support license feature. Formatting preserved with pixel-perfect fidelity. Pro tip: Convert DOCX to DocJSON once, work natively in JSON.
Custom WebAssembly layout engine replicates Word's pagination. Headers, tables, images render identically. Export matches screen pixel-for-pixel. All formatting preserved — merged cells, indents, hyperlinks. Suitable for contracts and financial reports.
Latest two versions of Chrome, Firefox, Safari, Edge — covers more than 95 percent of users. No plugins required. Consistent output across browsers. Tablets supported. Mobile not officially supported.
No. Processes entirely in-browser. Code/fonts load from CDN by default, but you can self-host. Document content never touches our servers. Simplifies GDPR, HIPAA, and SOC 2 compliance.
Base license includes PDF export and DocJSON. DOCX import/export requires DOCX Support add-on. If you only need PDF output, base license works. Contact sales for DOCX Support.
Yes. The Document Authoring SDK is framework-agnostic. Official guides for React, Vue, and vanilla JS. Initialize with createDocAuthSystem(), mount with createEditor(). Full TypeScript definitions. Also works with Angular, Svelte, Next.js.
Native JSON format for documents. Programmatic generation, version control with standard tools, inject API/database data, 10x faster than DOCX. Pro tip: Convert Word docs once to DocJSON as source of truth.
Yes. Embeds fonts, preserves vector graphics, includes clickable hyperlinks. Supports PDF/A for archival. Used for contracts, annual reports, insurance policies, and technical manuals.
Yes. Generate docs as JSON (Node, Python, C#, TypeScript), load into editor for review or immediate export. Invoices: merge database data. Contracts: combine clauses programmatically. Reports: pull charts from APIs. Type-safe and straightforward.
