Converting to WAV won't restore lost quality
Your MKV file has already undergone lossy compression. Converting to WAV preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Some metadata may not survive
Your MKV file may contain Matroska tags, chapter markers, attachments metadata. WAV has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.

About MKV to WAV Conversion
Short answer: yes, you can convert MKV to WAV online for free, and quality is well preserved with the right settings. Just upload your .mkv file to CocoConvert, pick WAV as the output, and click Convert. The whole process takes seconds.
Now for the details. MKV (Matroska) is an open container supporting virtually any codec, multiple audio tracks, and subtitles. WAV is uncompressed PCM audio — studio quality with no data loss, but large file sizes. Converting between these two formats lets you preserve files for long-term archival.
Full Name: MKV uses Matroska Video, while WAV uses Waveform Audio. Compression: MKV uses Lossy, while WAV uses None (uncompressed). Color Depth: MKV uses 8–10 bits (codec dependent), while WAV uses —.
Your MKV file is decoded and re-encoded as WAV. Converting MKV to WAV maintains high quality with CocoConvert's optimised encoder settings.
Common misconception: ""Converting MKV to WAV will improve the quality"" — in reality, no. mkv has already permanently discarded data during compression. converting to wav preserves what's left but cannot restore lost detail. the file will just be larger.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.

Video frames, subtitles, and chapter markers are discarded
The WAV file is saved with preserved metadata (title, artist, etc.) where possible
