Your files stay on your Mac.
Textile uses a compact, readable syntax for headings, lists, links, and inline emphasis. Converting to LaTeX rewrites those markers into the commands a TeX engine expects — headings become \section{}, bold becomes \textbf{}, lists become itemize blocks. The resulting .tex file is ready to compile or open in any LaTeX editor.
Drag one Textile file or an entire folder into Convertessa. All processing runs locally — nothing is uploaded.
Pick LaTeX from the output format list. Convertessa maps every Textile construct — headings, emphasis, links, blockquotes, and code spans — to its LaTeX equivalent.
Click Convert. Convertessa writes a .tex file alongside each source document. Open it in your LaTeX editor or run it through your TeX engine straight away.
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. Pass the folder path on the command line (convertessa ./docs/ --to tex) or drag the folder into the app. Convertessa processes every .textile file in the folder and writes a matching .tex file next to each one.
No. Convertessa runs entirely offline. Your Textile files are read from disk, converted in memory, and written back to disk — no network connection is made at any point.
Convertessa converts headings, paragraphs, bold, italic, inline code, code blocks, unordered and ordered lists, blockquotes, and hyperlinks to their LaTeX equivalents. The output is plain LaTeX source with no custom macros, so it compiles with any standard TeX distribution.
