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.

About the E-AC3 format
E-AC3 (Dolby Digital Plus) is the streaming-generation successor of the classic AC3: better audio at roughly half the bitrate, support for up to 15.1 channels, and the mandatory audio codec of UHD Blu-ray and most streaming-TV platforms. Netflix, Amazon and broadcast IPTV all ship it.
For authoring streaming deliverables, E-AC3 at 192-384 kbps is the safe standard. For editing or everyday playback, convert it to WAV/MP3 first — few audio editors accept it natively.
+Strengths
- ✓Better quality than AC3 at half the bitrate
- ✓The streaming-TV and UHD Blu-ray standard
- ✓Up to 15.1 surround channels
!Limitations
- −Poor editor/playback support outside TV pipelines
- −Lossy — not for archival masters

Frequently asked questions
Is this SHN to E-AC3 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 E-AC3?
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 E-AC3 reduce audio quality?
If E-AC3 is lossless, the output contains everything the SHN file contains — no further loss is added. If E-AC3 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.
