Your files stay on your Mac.
Converting OpenDocument Text to Textile transforms a binary .odt document into plain-text Textile markup. Headings, bold, italic, and links are expressed as lightweight punctuation — ready for wikis, static-site generators, or version control. The conversion runs entirely on your Mac; no file is uploaded.
Drag one .odt file or an entire folder onto Convertessa. Batch mode converts every OpenDocument Text file in the folder in a single pass.
In the output format list, Choose Textile. Convertessa extracts the document structure — headings, paragraphs, inline styles — and maps each element to its Textile equivalent.
Click Convert. Convertessa writes one .textile file per source document, preserving the original structure as plain-text markup. Files never leave 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.

New formats, new features, and fixes — every release, on the record.
Yes. Convertessa maps OpenDocument Text styles to their Textile equivalents: heading levels become h1.–h6. notation, bold becomes *bold*, and italic becomes _italic_. Inline markup is preserved as faithfully as the Textile format allows.
Yes. Drop a folder onto Convertessa or run convertessa ./folder/ --to textile from the terminal. Every .odt file in the folder is converted in one pass, producing one .textile output file per source document.
No. Convertessa runs entirely on your Mac. Your .odt files are read and written locally — nothing is sent to a remote server at any point during conversion.
