How to open a Word document online
Open your .docx
Drag & drop the file onto the viewer or click Open .docx. The file is read locally; nothing is uploaded.
Read
Headings, paragraphs, lists, tables, images and hyperlinks render directly. Use the find bar (magnifier icon) to jump to a phrase.
Export
Download as .html for the web, .md for Markdown-friendly tools (Git, Notion, Obsidian), or .txt for the plainest possible text.
Print or save as PDF
Print opens the browser dialog; pick "Save as PDF" as the destination for a tidy PDF copy.
Open another
Click Open .docx again — the previous document is replaced. Nothing is cached after you close the tab.
About the HCODX Word document viewer
This is a real online Word viewer for the modern .docx format (Office Open XML). The page uses the open-source mammoth.js library to parse the .docx zip and convert it to clean, semantic HTML — entirely in your browser.
How it works
A .docx file is a ZIP containing XML. When you drop a file, the browser reads it as an ArrayBuffer, mammoth.js unzips it, walks the document XML and emits HTML without inline styles — clean <h1>, <p>, <ul>, <table> tags. Images are embedded as Base64 data: URIs so they render inline.
What it renders well
Headings (Heading 1–6), paragraphs, bold / italic / underline, ordered & unordered lists (with nesting), tables, embedded raster images (PNG, JPG, GIF), hyperlinks, blockquotes, line breaks, page breaks (visible as horizontal rules in HTML).
What it flattens
Custom fonts (replaced with system stack), exotic page layouts (multi-column, manual frames), drawn shapes and SmartArt, equations (rendered as plain text), tracked changes (shown as accepted), comments (omitted), some footer/header content. For pixel-perfect rendering of unusual documents, open in Microsoft Word or LibreOffice Writer.
.doc vs .docx
This viewer reads .docx only. The legacy .doc format (Word 97-2003) uses a binary file format that mammoth doesn't parse. Convert legacy .doc files in Word or LibreOffice first, or use a conversion service.
Export formats
HTML wraps the rendered body in a standalone document with print-friendly CSS. Markdown walks the HTML and emits GitHub-flavoured Markdown — headings (#, ##), lists, bold (**), italic (*), tables, links. Plain text strips every tag and collapses whitespace, leaving only the words.
Privacy
Nothing is uploaded. Open the Network tab in your browser's DevTools to verify — no request leaves the page with your document data. The file is read with FileReader, parsed with mammoth.js, rendered to the DOM, and discarded when you close the tab.

No — only the modern .docx format (Office Open XML). Legacy .doc files use a binary format that this viewer cannot parse. Convert with Word or LibreOffice first.
Never. The file is read with the browser's FileReader API and parsed by mammoth.js locally — nothing is sent to a server. You can verify in DevTools → Network: no outbound request carries your data.
Headings, paragraphs, bold/italic/underline, ordered and unordered lists, tables, embedded images, hyperlinks, blockquotes and footnotes. Advanced formatting (drawn shapes, equations, multi-column layouts, tracked changes) is flattened.
Yes. The toolbar has one-click download buttons for .html (clean standalone HTML), .md (GitHub-flavoured Markdown), and .txt (plain text with formatting stripped).
Yes — the toolbar collapses, the page renders fluidly on narrow screens, and tap-to-zoom works as expected. Tested on iOS Safari, Chrome Android and Samsung Internet.
