Docx Footnote Endnote Preservation

DOCX conversion now preserves footnotes and endnotes as Markdown reference links

2026-07-31

Starting 2026-07-31, MarkItDown Online DOCX-to-Markdown conversion preserves footnotes and endnotes. Previously, footnote and endnote content was dropped during conversion because the Markdown spec has no native equivalent. The new behavior converts each footnote to a reference-style link with a stable anchor, and collects all footnote text in a dedicated section at the end of the document.

How footnotes are represented

Each footnote in the source DOCX becomes a reference-style link in the Markdown body. The link target is a numbered anchor (e.g., [^1], [^2]) that resolves to a footnote definition block at the end of the document. The footnote text preserves inline formatting — bold, italic, and code spans survive the conversion.

Practical impact

Legal contracts, academic papers, and technical specifications that rely on footnotes for citations now convert without losing reference material. The footnote section at the end of the Markdown output is compatible with most Markdown renderers that support extended syntax. Feedback: sapsap@qq.com.
