Your files stay on your Mac.
Convertessa reads your .tex source and writes clean .rst output that Sphinx, docutils, or any RST-aware tool can consume directly. Structural elements — headings, lists, code blocks, and inline markup — are mapped to their reStructuredText equivalents. Everything runs locally; no files are uploaded or processed in the cloud.
Drag one .tex file or an entire folder of documents onto Convertessa. Nested folders are walked automatically for batch runs.
Pick reStructuredText from the output format list. Convertessa converts each file to .rst — no other setting required.
Click Convert. Your .rst files appear in the output folder immediately, ready to drop into a Sphinx project or any RST-aware documentation pipeline.
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.
No. Convertessa runs entirely offline. Your files are read and written on your own machine — nothing is uploaded to any server.
Yes. Drop a folder onto Convertessa or pass a directory path via the CLI (convertessa ./docs --to rst) and every .tex file inside is converted in one pass.
Yes. Convertessa strips embedded metadata from document files during conversion, so your .rst output contains only the document content.
