Your files stay on your Mac.
MXF packages audio and video tracks together in a professional broadcast container. Converting to Apple CAF extracts the audio stream and writes it as Apple's Core Audio Format, ready for Logic Pro, Core Audio APIs, or any Apple-native audio tool. Every file stays on your Mac — nothing is uploaded.
Drag one MXF file or an entire project folder into Convertessa. Batch mode picks up every MXF in the folder and processes them in one pass.
Choose Apple CAF from the output format list. Convertessa targets the audio stream inside each MXF and writes a CAF file preserving the original sample rate, bit depth, and channel layout.
Click Convert. Convertessa works entirely locally — your footage never leaves the Mac. Converted CAF files land in the 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.
No. Apple CAF is a lossless container, so the audio data from your MXF is preserved exactly — same sample rate, bit depth, and channel layout. No quality is lost in the process.
Yes. Drop a folder onto Convertessa or use the CLI batch command: convertessa ./footage/ --to caf. Every MXF in the folder is converted in one pass.
Yes. Convertessa preserves the channel layout from the MXF source — mono, stereo, and multi-channel tracks are all written into the CAF file as-is.
