Your files stay on your Mac.
Convertessa reads each Word document and writes a DocBook XML file with headings, paragraphs, lists, and inline elements mapped to their DBK equivalents. The conversion runs entirely on your Mac — no file is uploaded to any server. Batch-convert a whole folder of .docx files in a single pass.
Drag one or more .docx files into Convertessa, or point it at a folder to process every Word document inside.
Pick DocBook from the output format list. Convertessa sets DBK as the target and queues your files for conversion.
Click Convert. Convertessa writes a .dbk file alongside each source document, preserving your document structure as valid DocBook XML. Nothing leaves your Mac.
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.
