MXF to CAF Converter
Processing entirely on your device — large files may take a moment.
Material Exchange Format and Core Audio Format exist for different jobs: MXF is the broadcast-industry media container — XDCAM, P2 cameras and TV stations hand off program material as MXF with embedded metadata. Convert CAF files to WAV or MP3 for use outside the Apple ecosystem.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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 CAF format
CAF (Core Audio Format) is Apple's container for pro audio: 64-bit file offsets for recordings of any length, any codec as payload (PCM, ALAC, AAC), and time-stamped MIDI-style event chunks. Logic Pro exports it and macOS system sounds ship in it.
ffmpeg decodes the common PCM/ALAC payload variants, converting CAF to WAV or MP3 for use in any non-Apple DAW, player or web player.
+ Strengths
- ✓64-bit offsets — no size ceilings
- ✓Native to Logic Pro pipelines
- ✓Flexible codec payload
! Limitations
- −Apple-centric — rare outside macOS
- −Some CAF variants (UUID chunks) unsupported
- −Tag metadata Apple-specific
Why convert MXF to CAF?
Converting makes sense where the strengths of CAF meet what MXF cannot give you. 64-bit offsets — no size ceilings 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 CAF 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 CAF?
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.
Does converting MXF to CAF re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of CAF, staying in sync with the video. If your MXF file has multiple audio tracks, the first one is used.
