SHN to ALAC Converter
Processing entirely on your device — large files may take a moment.
SHN (Shorten) is the granddaddy of lossless audio — the format of every live-concert trade archive from the 1990s. Convert ALAC to FLAC for non-Apple players, or MP3 for sharing.
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 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 ALAC format
ALAC (Apple Lossless Audio Codec) is Apple's FLAC equivalent: bit-exact lossless compression inside an MP4 container, opened-source in 2011 and now native on every Apple device and most server-side pipelines. It is what iTunes Store sells as "lossless" and what iPhone recordings encode to by default.
For non-Apple players FLAC is the safer target, and conversion is sample-exact in both directions — the decode is handled by ffmpeg's native ALAC decoder without any Apple runtime.
+ Strengths
- ✓Native on every Apple device
- ✓Open source since 2011
- ✓Reasonable sizes inside MP4
! Limitations
- −Outside Apple ecosystems FLAC wins
- −Slightly worse ratios than FLAC
- −Confusing .m4a extension doubles as lossy

Frequently asked questions
Is this SHN to ALAC 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 ALAC?
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 SHN to ALAC reduce audio quality?
If ALAC is lossless, the output contains everything the SHN file contains — no further loss is added. If ALAC 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 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.
