Import a DOCX file, make changes, and export a high-fidelity PDF or DOCX file without touching a backend. The frame below is the live web-based DOCX editor component — see the JavaScript DOCX editor library in action by editing sample documents.
JAVASCRIPT DOCX EDITOR DEMO
The embedded editor lets you edit DOCX files in the browser with full fidelity. Play around with it and see what’s possible compared to other rich text libraries. To get started, edit a sample document or import your own DOCX file.
WebAssembly loads in seconds, runs fully offline, and handles megabyte‑scale documents. Your data never leaves the browser — compliance stays simple.
Page‑based canvas renders DOCX files exactly and exports PDF/DOCX files that mirror the screen. Stakeholders sign off on what they actually see.
Readable JSON, type‑safe APIs, and granular commands speed up automation and custom UIs. Faster builds cut the total cost of ownership.
Shortcuts, global undo/redo, and smooth scrolling feel native, even on huge files. Instantly familiar — users keep typing, not hunting for buttons.
Load, modify, or generate documents as straight JSON. Then render them instantly in the editor.
Wrap the component in React, Vue, Svelte, or plain JavaScript — the API surface remains identical.
Clear guides, runnable examples, and a clone-ready GitHub repository make you productive in minutes.

Yes. Nutrient’s browser-based DOCX editor (Document Authoring) runs entirely client-side via WebAssembly. You can edit a DOCX file in the browser — even offline or in air-gapped environments — without touching any server resources.
Out of the box, the JavaScript DOCX editor SDK loads and saves PDF and DocJSON files. To open or export DOCX files, enable the optional DOCX Support feature in your license.
The WebAssembly DOCX viewer and editor share a page-based layout engine that mirrors desktop Word. Headers, footers, tables, and page breaks are preserved for pixel-perfect prints and archives.
The current versions of Chrome, Firefox, Safari, and Edge are fully supported. Because the component is standards-based, no plugins or extensions are required.
No. All processing happens in the user’s browser. You control where documents are stored, making compliance and data-governance mandates easier to meet.
Yes. DOCX handling is unlocked by adding the DOCX Support feature to your Document Authoring license. PDF and DocJSON are available in every tier.
Absolutely. The core API is framework-agnostic, and sample wrappers for React, Vue, and vanilla JavaScript are available in the developer guides.
DocJSON is the editor’s native JSON format. It lets you generate, diff, and patch documents programmatically, and then render them instantly in the browser.
Yes. The WebAssembly DOCX viewer embeds fonts and preserves layout, producing PDFs suitable for contracts, reports, and any print-critical workflow.
Yes. Because DocJSON is plain JSON, you can build templates or merge data on the server or client, and then load the result directly into the browser-based DOCX editor for final tweaks or exporting.
