WordをMarkdownに変換

A Word to Markdown converter that turns a .docx document into clean Markdown in your browser, mapping its headings, lists and inline formatting so you can move content out of Word and into a docs site, wiki or repository.

The .docx is converted entirely in your browser, so the file never leaves your device, which keeps confidential documents private.

It uses mammoth, a converter that reads the document's semantic structure rather than its visual styling. That means it works best with documents that use real Word styles, Heading 1, Heading 2, list styles, rather than text that was just made big and bold by hand.

Headings, ordered and unordered lists, bold, italics and links all map to their Markdown equivalents so the result is clean and ready to use.

Images are intentionally omitted, because Word embeds them as large inline data that would bloat the Markdown. The text and structure come through; you can add images back separately if you need them.

For the best result, make sure your document uses Word's built-in heading and list styles. Manually formatted text carries no structure for the converter to read, so it comes through as plain paragraphs.

Only the modern .docx format is supported. If you have an older .doc, open it in Word and save it as .docx first.
