Why we built this

Opening a .docx file shouldn't require a Microsoft Office subscription, a cloud account, or uploading sensitive documents to a stranger's server. Yet for millions of people — students, freelancers, small businesses — that's exactly the barrier they face every day.

We built DOCX Hub to remove that barrier entirely. Using modern browser APIs and best-in-class open-source libraries, we pushed the entire document-processing pipeline into the browser itself. The result: a tool that is faster, more private, and completely free — with no compromises.

How it works

When you open a file, your browser's native File API reads it into a JavaScript ArrayBuffer entirely in memory. From there, our pipeline hands the data to specialised open-source engines:

Viewer
docx-preview

Renders the full DOCX layout — tables, images, headers, footers — directly as HTML inside your browser.

Editor
Mammoth.js

Converts DOCX structure to clean, semantic HTML that you can edit inline and re-export.

Converter
jsPDF + html2canvas

Renders the document and captures it as a high-quality, downloadable PDF — zero server contact.

Metadata
JSZip + XML parsing

Unzips the DOCX container and reads raw Office Open XML properties for full metadata inspection.

Our principles

🔒 Privacy by design

Files are processed locally. There are no upload endpoints. There never will be.

Speed above all

No round-trips to a server means near-instant rendering regardless of your internet speed.

🆓 Free, forever

No freemium tiers, no watermarks, no file-size limits hidden behind a paywall.

🌍 Accessible everywhere

Works on any device with a modern browser — Windows, Mac, Android, iPhone — without installing anything.
