W64 to MP2 Converter
Processing entirely on your device — large files may take a moment.
W64 (Sony Wave64) is WAV beyond its 4 GB ceiling — a 64-bit riff on the RIFF container that Sony Vegas and high-resolution field recorders emit for hours-long sessions. Broadcast MP2 files convert to MP3 for players that no longer ship the decoder.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the W64 format
W64 is Sony's Wave64 — what happens when WAV's 32-bit size fields run out of road. A RIFF variant with 64-bit offsets, it shrugs off the 4 GB ceiling that makes plain WAV choke, which is why long field-recording sessions and Sony Vegas projects land in W64.
Inside, it is the same uncompressed PCM as WAV — ffmpeg hands W64 to WAV, FLAC or MP3 without touching a single sample, so conversion is purely about container compatibility.
+ Strengths
- ✓No 4 GB size ceiling — hours-long recordings
- ✓Bit-exact PCM, same as WAV inside
- ✓Standard in Sony Vegas workflows
! Limitations
- −Almost nothing outside Sony tools opens it
- −Uncompressed — very large files
- −Legacy niche — new tools prefer RF64
About the MP2 format
MP2 (MPEG-1 Audio Layer II) is MP3's older, simpler sibling — and despite losing the consumer war, it never left broadcasting: digital TV (DVB), DVD-audio tracks and European radio still transmit MP2 daily. Its decoder is trivial, which is exactly why broadcasters love it.
Consumer devices have quietly dropped the decoder, so MP2 files from TV recordings or radio captures need conversion to MP3 for anything portable. The audio itself is often 256–384 kbps — genuinely good quality hiding in a forgotten format.
+ Strengths
- ✓The broadcast standard — still transmitted daily
- ✓Often high bitrate (256–384 kbps)
! Limitations
- −Dropped by consumer players
- −Less efficient than MP3 at equal quality

Frequently asked questions
Is this W64 to MP2 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 W64 to MP2?
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 converting W64 to MP2 reduce audio quality?
If MP2 is lossless, the output contains everything the W64 file contains — no further loss is added. If MP2 is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
Can I convert a whole folder of W64 files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
