Your files stay on your Mac.
Convertessa reads your .tex source files and writes DocBook XML — structured, schema-valid markup ready for multi-format publishing pipelines and documentation toolchains. The conversion runs entirely on your Mac: no upload, no cloud service, no internet connection required. Drop a single file or an entire project folder and get DocBook output in seconds.
Drag one .tex file or a whole folder of LaTeX source into Convertessa. Every file is processed locally — nothing leaves your Mac.
Choose DocBook from the output format list. Convertessa writes standard DocBook XML compatible with XSLT stylesheets, Pandoc, and documentation build chains.
Click Convert. Convertessa processes every file in the batch and saves the .dbk output to the destination folder you specify.
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 .tex files are read and written locally — no file is ever sent to a server or cloud service.
Yes. Drop a folder onto Convertessa or pass a directory to the CLI: convertessa ./project/ --to dbk. Every .tex file in the folder is converted in one pass.
Convertessa strips embedded metadata from the source during conversion. The resulting .dbk file contains the document structure and content without author or tool metadata carried over from the .tex file.
