MXF to F4B Converter
Processing entirely on your device — large files may take a moment.
Convert F4B audiobooks exactly like M4B — to MP3, M4A or WAV. 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 F4B format
M4B is M4A wearing an audiobook badge: the same AAC audio in an MP4 container, plus chapter markers that Apple Books and Audible apps render as a scrubbing timeline. Buy an audiobook outside Audible and it likely arrives as M4B.
The format is deliberately chained to Apple's book ecosystem. Converting M4B to MP3 sets the book free: car stereos, gym players, old iPods and every app without chapter support will play it — though the chapter marks themselves are flattened away.
+Strengths
- ✓Chapter markers survive on Apple platforms
- ✓Efficient AAC audio
!Limitations
- −Chapters vanish in MP3 conversion
- −Non-Apple support is patchy

Frequently asked questions
Is this MXF to F4B 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 F4B?
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.
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.
Does converting MXF to F4B 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.
