Your files stay on your Mac.
DVD VOB files pack video, audio, and subtitle streams into a single container. Converting to WAV writes the audio track as an uncompressed PCM file — no lossy compression step is added on the way out. Convertessa runs entirely on your Mac; your files are never uploaded.
Drag one VOB file or an entire DVD folder into Convertessa. The app reads the audio stream directly from the container without unpacking the video.
Pick WAV from the output format list. WAV stores audio as uncompressed PCM, so no additional compression is applied to the extracted track.
Click Convert. Convertessa extracts the audio and writes a WAV file alongside your original. Everything runs locally — no internet connection required.
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.
WAV is an uncompressed format, so no lossy compression is introduced in the output. The audio is decoded from the VOB container and written as raw PCM — the result is as faithful to the source as the original encoding allows.
Yes. Drop a folder containing multiple VOB files onto Convertessa, or use the CLI: convertessa /path/to/dvd-folder --to wav. Each file is processed in one pass.
No. Convertessa runs entirely offline. All conversion happens on your Mac and your files never leave the machine.
