Your files stay on your Mac.
Convertessa reads the XML structure inside a .docx and rewrites it as plain-text Markdown. Word heading styles become # levels, bulleted and numbered lists become their Markdown equivalents, and bold and italic runs are preserved as **bold** and *italic*. The output is a clean .md file ready for static site generators, code editors, and version control — no proprietary formatting left behind.
Drag one .docx file or an entire folder onto Convertessa. Batch mode finds every Word document in the folder and queues them all in a single pass.
In the output list, Choose Markdown (.md). Convertessa maps Word paragraph styles to heading levels H1–H6 and converts lists, hyperlinks, bold, and italic to standard Markdown syntax.
Click Convert. Each .md file is written next to its source document. Nothing is uploaded — the conversion runs entirely on your Mac.

New formats, new features, and fixes — every release, on the record.
Convertessa preserves heading levels (H1–H6), bulleted lists, numbered lists, bold, italic, and inline hyperlinks. These map directly to standard Markdown syntax in the output .md file.
No. Convertessa converts the text and structural content of the .docx. Embedded images are not written into the .md file.
Yes. Pass a folder path on the command line — convertessa ./docs/ --to md — and Convertessa converts every .docx it finds, writing a .md file alongside each one.
