Your files stay on your Mac.
Convertessa reads your LaTeX source and maps its document hierarchy—parts, chapters, sections, and subsections—into OPML outline nodes. The resulting file imports directly into outliners, mind-mapping tools, and RSS readers that accept OPML. Files never leave your Mac.
Drag one .tex file or an entire folder of LaTeX sources onto Convertessa. The app queues every file for conversion.
Pick OPML from the output format list. Convertessa extracts the document hierarchy from each LaTeX file and structures it as OPML outline elements.
Click Convert. Each .tex file produces a matching .opml file beside the original. Sections become outline nodes and nested headings become child nodes.
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.
Convertessa maps \part, \chapter, \section, \subsection, and \subsubsection commands to nested OPML <outline> elements, preserving the document hierarchy depth.
Yes. Drop a folder onto Convertessa or run convertessa ./folder --to opml in the terminal. Every .tex file in the folder is converted and a matching .opml file is written beside each source.
Convertessa reads the structural commands that define the outline hierarchy. Package-specific macros and body text are not included in the OPML output—only the heading tree is extracted.
