Our mission
Document tools that
respect your privacy
DOCX Hub is a free, browser-based platform for working with Word documents. Every operation including viewing, editing, converting, and inspecting runs entirely inside your browser. Nothing ever leaves your device.
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 including students, freelancers, and small businesses, that is 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 is 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:
Renders the full DOCX layout including tables, images, headers, and footers directly as HTML inside your browser.
Converts DOCX structure to clean, semantic HTML that you can edit inline and re-export.
Renders the document and captures it as a high quality vector PDF with zero server contact.
Unzips the DOCX container and reads raw Office Open XML properties for full metadata inspection.
Our principles
Files are processed locally. There are no upload endpoints. There never will be.
No round-trips to a server means near-instant rendering regardless of your internet speed.
No freemium tiers, no watermarks, no file-size limits hidden behind a paywall.
Works on any device with a modern browser including Windows, Mac, Android, and iPhone without installing anything.
