Add your MXF file
Drop one or more .mxf files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Pulling the soundtrack out of a .mxf video into .aiff audio keeps what you can hear and drops the picture entirely. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Pulling the soundtrack out of a .mxf video into .aiff audio keeps what you can hear and drops the picture entirely. An .mxf file is a Material Exchange Format container, the professional broadcast industry's standard wrapper for camera masters and finished programs. Newsrooms, playout servers, and cameras like Sony XDCAM and Panasonic P2 all exchange .mxf because it binds video, audio, and detailed production metadata into one interoperable file.
An .aiff file is Apple's Audio Interchange File Format, storing uncompressed PCM audio much as WAV does on Windows. Mac-based studios have exchanged .aiff masters for decades, and Logic Pro sessions and sample libraries remain full of them. For this route the practical draw is bit-perfect audio identical in fidelity to WAV and loop and marker metadata that samplers actually read — balanced against as bulky as any uncompressed format, which is worth knowing before you commit a large batch.
The usual reason to take .aiff audio out of a .mxf file is that only the sound matters — a talk, interview, song, or podcast segment. Keeping the video stream would waste storage, and a dedicated audio file is easier to trim, tag, and play. On the source side, two files with the same .mxf extension can be structured completely differently (OP1a versus OPAtom), confusing consumer tools; on the target side, the payoff is bit-perfect audio identical in fidelity to WAV, which is exactly what you want for delivering masters from macOS-based studios.
| Aspect | Material Exchange Format (.mxf) | Audio Interchange File (.aiff) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Lossless — every pixel or sample is preserved exactly |
| How it stores data | every element is encoded as KLV (key-length-value) triplets, making files self-describing to any compliant parser | classic AIFF stores big-endian PCM, the opposite byte order from WAV, in COMM and SSND chunks |
| Strongest at | ingesting XDCAM and P2 camera cards into an edit | delivering masters from macOS-based studios |
| Weak spot | two files with the same .mxf extension can be structured completely differently (OP1a versus OPAtom), confusing consumer tools | as bulky as any uncompressed format |
| Metadata | extensive by design: structural metadata, descriptive schemes such as DMS-1, embedded timecode, and UMID identifiers are core parts of the specification | nAME, AUTH, and ANNO chunks provide basic text, marker and instrument chunks store loop data, and an ID3 chunk is a common unofficial extension used by iTunes |

Select .aiff in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if AIFF is selectable, the route is real and validated.
Press Convert. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid AIFF file. Outputs keep the original filename with the .aiff extension.
Since mxf is container-oriented and aiff is lossless-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .aiff itself requires.
Yes — the .mxf file is processed inside your browser tab and never uploaded. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded. Close the tab and the file is gone from memory.
macOS and all serious audio software open .aiff without hesitation, and Windows editors generally support it even though WAV is their default. Browsers offer partial support at best, and the format's size makes it a poor web choice regardless.
Much smaller — the video stream is usually 80–95% of a .mxf file's weight, and it is discarded entirely. The remaining audio is re-encoded at the bitrate implied by your quality setting.
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, extensive by design: structural metadata, descriptive schemes such as DMS-1, embedded timecode, and UMID identifiers are core parts of the specification; none of it is transmitted anywhere because the file never leaves your browser.
