WV to MKV Converter
Processing entirely on your device — large files may take a moment.
MKV is ideal for archiving movies with multiple audio tracks and subtitles intact. If your files are still in WV format, this page is the shortcut: WavPack is the hybrid lossless format — its unique lossy-plus-correction mode ships a small file that can be restored to bit-exact audio.
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 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
About the MKV format
MKV (Matroska) is the open container that refuses to say no: virtually any video codec, multiple audio tracks, multiple subtitle streams, chapters, attachments and menu structure in one file. It became the de facto standard for movie rips, anime releases and personal archives precisely because nothing needs to be thrown away.
The same generosity is its compatibility risk: smart players (VLC, mpv) handle everything, but smart TVs, consoles and car systems choke on exotic codec combinations inside MKV. It is also not a streaming standard, so web delivery runs through its subset, WebM.
+ Strengths
- ✓Unlimited tracks: audio, subtitles, chapters, attachments
- ✓Open specification, no licensing
- ✓Ideal archival container — nothing is lost
! Limitations
- −Device playback is hit-or-miss outside smart players
- −Not web/streaming native
Why convert WV to MKV?
Think of it as moving your file to the container that fits the job. Ratios slightly behind APE MKV works differently: Unlimited tracks: audio, subtitles, chapters, attachments If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this WV to MKV 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 WV to MKV?
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 WV to MKV reduce audio quality?
If MKV is lossless, the output contains everything the WV file contains — no further loss is added. If MKV 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.
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.
