SHN to MP2 Converter
Processing entirely on your device — large files may take a moment.
Broadcast MP2 files convert to MP3 for players that no longer ship the decoder. If your files are still in SHN format, this page is the shortcut: SHN (Shorten) is the granddaddy of lossless audio — the format of every live-concert trade archive from the 1990s.
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 SHN format
Shorten (SHN) is the 1993 lossless codec that made live-music trading possible: etree.org and the tape-trading community distributed entire concert recordings as SHN before FLAC existed. Its 32KB fixed frames and minimal header made it robust on FTP, its native habitat.
Converting SHN to FLAC is the standard modernization — sample-identical output, proper tags finally possible, and seeking that does not require decoding from the start of the file.
+ Strengths
- ✓Foundational live-music archive format
- ✓Extremely simple and stable
- ✓Decodes losslessly via ffmpeg
! Limitations
- −No seeking support
- −No tagging
- −16-bit PCM only
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
Why convert SHN to MP2?
Think of it as moving your file to the container that fits the job. No seeking support MP2 works differently: The broadcast standard — still transmitted daily If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this SHN 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 SHN 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.
Can I convert a whole folder of SHN 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.
Will converting SHN to MP2 reduce audio quality?
If MP2 is lossless, the output contains everything the SHN 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.
