Your files stay on your Mac.
Convertessa reads your .tex files and rewrites them as Textile markup, mapping LaTeX commands to Textile's heading, bold, italic, and link syntax. Lists, sections, and inline formatting translate directly; each output file lands beside its original. Nothing leaves your Mac.
Drag one .tex file or an entire folder into Convertessa. Every file in the folder is queued automatically.
Choose Textile from the output format list. Convertessa targets the exact Textile dialect your project needs.
Click Convert. Each .tex file is rewritten as a .textile file and saved beside your original — no upload, no server round-trip.
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.
Math environments are preserved as literal text in the Textile output. Convertessa converts document structure and text-formatting commands — it does not render equations to images or translate them to another notation.
Yes. Drop a folder onto Convertessa or run convertessa ./folder --to textile. Every .tex file in the folder is converted and each output file is saved beside its source.
No. Convertessa runs entirely on your Mac — your files never leave your machine. There is no cloud step, no account required, and no network connection needed.
