Your files stay on your Mac.
OPML packages structured outlines — podcast feeds, blogrolls, reading lists — as XML. Convertessa maps each outline item to an ICML story element so you can open the result directly in Adobe InCopy. The conversion runs entirely on your Mac; nothing is uploaded to a server.
Drag one OPML file or an entire folder onto Convertessa. Batch mode processes every .opml file in a single pass with no extra configuration.
Choose ICML (InCopy) from the output format list. Because ICML supports embedded content, you can set quality to control how that content is rendered in the output document.
Click Convert. Convertessa writes ICML files alongside your originals — open them straight in Adobe InCopy without any round-trip to a server.
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.
No. Conversion runs entirely on your Mac using native libraries. Your files never leave the machine.
Yes. Drag a folder onto Convertessa or pass the directory path to the CLI — convertessa ./folder --to icml — and every .opml file inside is converted in one pass.
Yes. Convertessa strips embedded metadata from the output, so the resulting ICML files contain only the document content mapped from your OPML outline.
