Your files stay on your Mac.
Converting an AsciiDoc file to plain text strips all markup syntax — headings, bold markers, attribute entries, and macro calls — leaving only the bare readable prose. The output is a clean .txt file containing the document's content without any AsciiDoc formatting characters. Everything runs locally on your Mac; your files are never uploaded.
Drag one .adoc file or an entire folder of documents into Convertessa. Batch conversion processes every .adoc file in one pass.
Choose Plain Text from the output format list. Convertessa will strip all AsciiDoc markup and write clean .txt files alongside your originals.
Click Convert. Plain-text files are saved instantly — no internet connection required, no files uploaded.
Images, audio, video, documents, archives and eBooks — all converted natively, right on your 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.

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.
