Your files stay on your Mac.
Convertessa reads your .muse files and writes standard LaTeX source you can hand straight to pdflatex, xelatex, or any TeX engine. Headings, lists, emphasis, and links map to their LaTeX equivalents without manual editing. Every conversion runs locally — no upload, no account, no network required.
Drag a single .muse file or an entire folder into Convertessa. Batch mode processes every file in one pass, preserving your folder structure in the output.
Choose LaTeX from the output format list. Convertessa targets the .tex format and writes one source file per input document.
Click Convert. Convertessa writes .tex files ready to compile with your preferred TeX engine — no intermediate steps needed.
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.
Common header directives — #title, #author, and #date — map to the corresponding LaTeX preamble fields. Body markup such as headings, bold, italics, links, and unordered lists converts to standard LaTeX commands.
Convertessa writes the document body as valid LaTeX source. Depending on your TeX setup you may want to add a document class declaration or custom preamble before compiling — the generated source is plain text you can open and edit in any editor.
Yes. Point Convertessa at a folder and it converts every .muse file it finds, writing a matching .tex file for each one. Use convertessa ./notes/ --to tex from the command line for the same result.
