Your files stay on your Mac.
Convertessa reads your .tex source and rewrites it as AsciiDoc syntax—headings, sections, lists, code blocks, and cross-references all mapped to their .adoc equivalents. The output is a plain-text file ready for Asciidoctor, Antora, or any AsciiDoc toolchain. Every file stays on your Mac; nothing is uploaded.
Drag one .tex file or an entire project folder onto Convertessa. Batch mode picks up every .tex file in the folder and processes them in a single pass.
Pick AsciiDoc from the output format list. Convertessa will write a .adoc file for each source document, placed alongside the originals.
Click Convert. Convertessa rewrites LaTeX commands and environments as AsciiDoc markup and saves the results immediately—no internet connection required.
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.
Yes. Headings, sections, ordered and unordered lists, code blocks, and inline emphasis are all mapped to their AsciiDoc equivalents. LaTeX environments with no direct AsciiDoc counterpart are wrapped in passthrough blocks so no content is silently dropped.
Yes. Point Convertessa at a folder and it converts every .tex file inside, writing a matching .adoc file for each. You can also use the CLI: convertessa ./docs --to adoc.
No. Convertessa runs entirely on your Mac. Your LaTeX source files never leave your machine.
