MXF to AU Converter
Processing entirely on your device — large files may take a moment.
Converting AU to WAV preserves the samples in a format every modern tool reads. If your files are still in MXF format, this page is the shortcut: MXF is the broadcast-industry media container — XDCAM, P2 cameras and TV stations hand off program material as MXF with embedded metadata.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the MXF format
MXF (Material Exchange Format) is the container broadcast television standardized on: XDCAM and P2 cameras record it, newsrooms hand off program material in it, and playout servers ingest it. Beyond the video and audio tracks it carries structured metadata — timecode, program markers, rights information — that plain MP4 cannot express.
For editing and review the container is the problem, not the content: converting MXF to MP4 or MKV keeps the H.264 video and PCM audio intact while making the file openable in any editor and shareable in chat. Broadcast cameras also interlace, so check the output for field order.
+ Strengths
- ✓Broadcast-grade metadata and timecode
- ✓Industry standard for program exchange
- ✓ffmpeg decodes XDCAM/IMX/D-10 variants
! Limitations
- −OP1a vs OP1b patterns differ by vendor
- −Metadata is dropped on conversion
- −Files are heavy (broadcast bitrates)
About the AU format
AU is Sun Microsystems' audio format from the Unix workstation age: a small header followed by µ-law (or PCM) samples. Java's applet era shipped it everywhere, and old Unix sound tooling still emits it.
Modern players increasingly skip it. Converting AU to WAV preserves the samples bit-for-bit while moving the file into universal territory — the standard rescue path for system sounds and old recordings.
+ Strengths
- ✓Simple, lossless sample storage
- ✓Native to old Unix/Java tooling
! Limitations
- −µ-law flavor sounds dated and mono
- −Dropped by modern players
Why convert MXF to AU?
Converting makes sense where the strengths of AU meet what MXF cannot give you. Simple, lossless sample storage Meanwhile OP1a vs OP1b patterns differ by vendor One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MXF to AU converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for MXF to AU?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of AU, staying in sync with the video. If your MXF file has multiple audio tracks, the first one is used.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
