Your files stay on your Mac.
MXF is a broadcast-grade container that wraps video, audio, and metadata into a single file. Converting to WavPack extracts the audio track and encodes it as a lossless .wv file — every sample is preserved exactly. The entire process runs on your Mac; your footage never leaves the machine.
Drag one MXF file or an entire folder into Convertessa. The app reads the embedded audio tracks directly from each MXF container.
Choose WavPack from the output format list. Convertessa will losslessly encode each extracted audio track to a .wv file.
Click Convert. Convertessa processes every file locally and writes one .wv file per MXF — 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.
Yes. WavPack is a lossless codec, so the decoded audio is bit-for-bit identical to the source. No audio data is discarded when converting from MXF.
Yes. Drag the folder into Convertessa, or run convertessa *.mxf --to wv in your terminal to batch-convert every MXF in the current directory.
No. Convertessa runs entirely offline on your Mac. Your footage and the resulting WavPack files never leave your machine.
