Your files stay on your Mac.
MPEG-TS bundles video and audio into a single transport stream used by DVRs, IPTV recordings, and broadcast captures. Convertessa reads the audio track, re-encodes it as Ogg Vorbis, and writes the result to your chosen folder. Nothing leaves your Mac — the entire conversion runs offline.
Drag one .ts file or an entire folder of recordings onto Convertessa. The app queues every file instantly — no upload, no file-size ceiling.
Pick Ogg Vorbis from the output list, then set quality to taste. A higher quality value preserves more audio detail at the cost of a larger file.
Click Convert. Convertessa processes every file locally and saves the .ogg output alongside the originals or in a destination folder you specify.
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.
Convertessa reads the primary audio track embedded in the transport stream. This covers the vast majority of DVR recordings, IPTV streams, and broadcast captures.
Ogg Vorbis is a lossy format — quality trades file size against audio fidelity. A mid-range setting handles speech and general listening well; raise it for music or archival use.
Yes. Drop a folder onto Convertessa or pass a directory path to the CLI. Every .ts file inside is queued and converted to Ogg Vorbis in one pass.
