Your files stay on your Mac.
Convertessa reads your .tex file and maps LaTeX structure — section headings, paragraphs, bold, italic, lists, and inline code — into standard Markdown syntax. The result is a clean .md file ready to drop into GitHub, a documentation site, or any Markdown editor. All processing runs locally; files never leave your Mac.
Drag one .tex file or an entire folder of LaTeX source onto Convertessa. Batch mode converts every file in the folder in one pass.
Choose Markdown from the output list. Convertessa maps LaTeX headings, emphasis, lists, and inline code to their .md equivalents.
Click Convert. Converted .md files land next to the originals. No upload, no account, 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.
Convertessa maps \section and \subsection to Markdown headings, \textbf to bold, \textit to italic, itemize and enumerate to Markdown lists, and \verb to inline code. LaTeX-specific commands that have no Markdown equivalent are stripped cleanly.
Yes. Drop a folder onto Convertessa, choose Markdown from the output list, and every .tex file in that folder is converted in one pass. You can also run convertessa ./folder --to md from the command line.
No. Convertessa runs entirely on your Mac. Your .tex files are never uploaded, transmitted, or cached outside your machine.
