Your files stay on your Mac.
Convertessa reads your .md files and writes them out as .docx Word documents, entirely on your Mac with no upload required. Headings, paragraphs, lists, and code blocks are mapped to their Word equivalents. Convert a single file or a whole folder in one command.
Drag one or more .md files — or an entire folder — into Convertessa. Files stay on your Mac throughout; nothing is uploaded.
Pick Word (.docx) from the output format list. Convertessa maps every Markdown element to the matching Word style, preserving document structure.
Click Convert. Your .docx files appear alongside the originals, with metadata stripped and structure intact.
Images, audio, video, documents, archives and eBooks — all converted natively, right on your Mac.
Pick a format you have — see everything Convertessa can turn it into.
Convert hundreds of files at once with per-type group defaults and individual overrides.
First-class support for HEIC, AVIF and WebP — encode and decode, both ways. Read JPEG XL and a dozen more modern formats too.
Drop files anywhere on the window. Native, instant, and exactly what you’d expect on a Mac.
Dial in compression, resolution and bitrate. Keep originals pristine or shrink for sharing.
Never overwrite a file by accident. Convertessa appends safe suffixes automatically.
Every job is logged locally. Re-run a previous conversion or revisit recent outputs in a click.
Bundle your converted files straight into a single ZIP, TAR or 7z — packaged and ready to share the moment a job finishes.
Right-click any file in Finder and choose Convert. A Quick Action handles it on the spot — no need to open the app first.
Shrink Convertessa to a tidy mini window that tucks into a corner — just a drop zone and a format picker for quick, one-off conversions.
No cloud. No account. No upload. Every conversion happens entirely on-device, using the power already in your Mac. What you convert is nobody’s business but yours.
Script conversions, wire them into your build, or batch a folder from the terminal. The same engine, no GUI required.

New formats, new features, and fixes — every release, on the record.
No. Convertessa runs entirely on your Mac. Your .md files are never sent to any server — conversion happens locally, offline.
Yes. Drag a folder onto Convertessa or run convertessa ./folder/ --to docx in the terminal to batch-convert every Markdown file inside in one pass.
No. Convertessa strips metadata from the output file, so your .docx contains only the document content — no embedded author, creation date, or other document properties from the source.
