About the SNDT format
SNDT is the Sound Tool sample format for MS-DOS — an uncompressed raw PCM cousin of SNDR found in retro archives.
ffmpeg decodes it natively inside your browser — the audio track is re-encoded to your chosen format with nothing ever uploaded.
+Strengths
- ✓Decoded natively by ffmpeg
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
!Limitations
- −Legacy niche format
- −Modern tools rarely open it
- −Keep the original for archival round-trips
About the WV format
WavPack's signature trick is the hybrid mode: encode once into a small lossy .wv plus a tiny .wvc correction file — together they are bit-exact lossless, apart the small file plays like a high-quality MP3. It also offers pure lossless and pure lossy modes in the same container.
Full WavPack files decode losslessly through ffmpeg into FLAC or WAV; hybrid correction files are handled by the original encoder only, so a .wvc alone cannot be restored.
+Strengths
- ✓Unique hybrid lossy+correction mode
- ✓Fast decode, open source
- ✓Error-robust streaming modes
!Limitations
- −Ratios slightly behind APE
- −.wvc correction files are orphaned here
- −Hardware support rare

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