Your files stay on your Mac.
DocBook is a verbose XML schema built for structured technical documentation. Converting to Textile produces compact, human-readable markup that editors, wikis, and static site tools can consume directly. Convertessa runs the entire conversion on your Mac — no internet connection, no upload.
Drag one .dbk file or an entire folder of DocBook documents into Convertessa. Batch mode processes every file in the folder in a single pass.
Choose Textile from the output format list. Convertessa maps DocBook elements — sections, paragraphs, lists, inline code, and emphasis — to their Textile equivalents.
Click Convert. Your Textile files land in the output folder immediately. The conversion runs entirely on your Mac — nothing is uploaded.
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. Convertessa removes embedded metadata from DocBook documents during conversion, so the resulting Textile files contain only document content.
Yes. Drop a folder onto Convertessa or run convertessa ./folder/ --to textile on the command line. Every .dbk file in the folder is converted in one pass.
