Your files stay on your Mac.
Convertessa reads your Textile source and maps its heading hierarchy into OPML nodes, producing a valid XML outline ready for any outline processor or feed aggregator. The document structure is preserved—top-level headings become root items and nested headings become child nodes. Files never leave your Mac.
Drag one file or an entire folder onto Convertessa. Batch mode picks up every .textile file in the folder and processes them in a single pass.
Choose OPML from the output format list. Convertessa targets the OPML 2.0 spec so the result opens in any compatible outline editor or aggregator.
Click Convert. Convertessa parses each Textile document, maps headings to nested outline nodes, and writes the .opml file alongside the original. Embedded metadata is stripped from the output.
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.
Each Textile heading level (h1–h6) becomes a nested <outline> element. An h1 produces a root node, h2 a first-level child, and so on. Body text between headings is attached as the text attribute of the nearest parent node.
Yes. Drag the folder onto Convertessa or run convertessa ./folder/ --to opml. Every .textile file in the folder is processed in one pass and each receives its own .opml output file.
Yes. Convertessa removes embedded document metadata before writing the OPML file, so author tags, timestamps, and similar properties are not carried over into the outline.
