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 MP4 format
MP4 (MPEG-4 Part 14) is the universal delivery container of digital video. It wraps H.264, HEVC or AV1 video with AAC audio, and its structure — separate metadata (moov) and media atoms — is what makes streaming, seeking and fast-start playback possible. Phones, cameras, TVs, browsers and every social platform assume MP4 first.
Quality is entirely a function of the codec and bitrate chosen at encode time, so an MP4 can be a 10 Mbps HEVC master or a postage stamp. That flexibility plus total playback coverage is why nothing has displaced it in twenty years — conversion between formats almost always ends in MP4.
+ Strengths
- ✓Plays on every device and platform in existence
- ✓Streaming-ready structure (fast start, seeking)
- ✓Choice of modern codecs: H.264, HEVC, AV1
! Limitations
- −Quality depends entirely on encode settings
- −HEVC variants hit licensing gaps on some platforms

Frequently asked questions
Is this SHN to MP4 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 MP4?
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 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.
