Your files stay on your Mac.
Converting a Jupyter Notebook to LaTeX extracts your code cells, markdown prose, and inline outputs into a structured .tex source file. You can compile it with any LaTeX toolchain to produce publication-ready PDFs. The entire conversion runs on your Mac—your notebooks are never uploaded anywhere.
Drag one or more .ipynb files onto Convertessa, or use the folder picker to queue an entire project directory at once.
Choose LaTeX from the output format list. Convertessa reads the notebook structure and maps each cell type to its LaTeX equivalent—code blocks, prose, section headings, and figure environments.
Click Convert. Convertessa writes a .tex file for each notebook, preserving the original resolution of any embedded images. Open the result in your LaTeX editor or run pdflatex directly.
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 each cell type to its LaTeX equivalent: code cells become verbatim blocks, markdown cells are converted to LaTeX prose and section headings, and embedded image outputs are written as figure environments at their original resolution.
Yes. Drag a folder onto Convertessa or run convertessa ./notebooks/ --to tex in the terminal to batch-convert every .ipynb file in the directory.
No. Convertessa runs entirely on your Mac. Your .ipynb files are never sent to any server or cloud service.
