Word converter opens a .docx to read its content where Word is not installed, and switches it into three more portable text formats: HTML (a complete web page with base styling), plain text and Markdown (heading levels, bold and italic, lists, tables, links and images kept). Parsing uses the mammoth library inside the browser, while the preview uses a separate renderer that tries to reproduce the page layout.

Its output is text-shaped. For PDF use Word to PDF; to convert between HTML and Markdown, HTML ↔ Markdown is all you need.

1. 01Upload a .docx— only Word 2007 and later .docx files are accepted; for an old .doc the tool says “Save it as .docx in Word or WPS Office first”.
2. 02Read the preview— the Preview tab is active by default and reproduces the layout as far as it can; WordArt, SmartArt and similar may not appear, which does not affect the other outputs.
3. 03Switch format— the HTML, Plain text and Markdown tabs each show a read-only text box; a total character count sits under the plain text.
4. 04Copy or download— every tab has Copy … and Download …, giving .html, .txt and .md files under the original name; the HTML is a full page with <!DOCTYPE>, font and table styles. When the document uses styles mammoth cannot map, the first 3 conversion notes are listed.

Input

— a single .docx only; .doc, .rtf and .odt cannot be read directly.

Kept

— heading levels, paragraphs, bold, italic, strikethrough, ordered and unordered lists (including nested), tables, hyperlinks, images (inlined as data URLs), code and quotes.

Lost

— headers and footers, footnotes and endnotes, comments and tracked changes, text boxes and WordArt, fonts, sizes and colors, page layout and columns, and table-of-contents fields; the Markdown output is a basic subset, and complex nesting is simplified.

Preview and output differ

— the preview uses a different renderer and may look closer to the original than the HTML or Markdown; trust the downloaded file.

What it does not do

— it does not produce PDF (use Word to PDF), does not edit and save the .docx and does not merge documents; for HTML ↔ Markdown conversion, use HTML ↔ Markdown.

The .docx is parsed, previewed and converted in your browser; the file contents are never uploaded to any server, and the data is released from memory when you close the page.
