Your files stay on your Mac.
OPML encodes hierarchical outlines as XML — used for podcast feeds, reading lists, and structured notes. Convertessa maps each outline node to heading levels and body paragraphs in a .docx file. Open the result in Word, Pages, or Google Docs and start editing right away.
Drag one .opml file or an entire folder onto Convertessa. Batch mode processes every file in the folder in one pass.
Pick Word (.docx) from the output format list. Set quality for any embedded media, then confirm your output folder.
Click Convert. Convertessa writes one .docx per .opml file. Your originals are untouched and 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.

New formats, new features, and fixes — every release, on the record.
Yes. Each nesting level in the OPML tree maps to a corresponding heading level in the Word document, so your outline structure survives the conversion intact.
Yes — drag a whole folder onto Convertessa or run convertessa ./folder --to docx from the command line. Every .opml file in the folder is converted in one pass.
No. Convertessa runs entirely offline. Your .opml files are read and written locally; nothing is uploaded to any server.
