S16 to MP2 Converter
Processing entirely on your device — large files may take a moment.
16-bit PCM (raw) and MPEG-1 Audio Layer II exist for different jobs: S16 is headerless 16-bit little-endian PCM — the lingua franca of DSP tool output and embedded audio logs, with no rate or channel info inside. Broadcast MP2 files convert to MP3 for players that no longer ship the decoder.
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 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 S16 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 S16 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.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
Can I convert a whole folder of S16 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.
