Extract Audio from Blu-ray Rips, Anime, and Downloaded Videos
MKV is the container of choice for high-quality video archiving. Blu-ray rips, anime encodes, fan-subbed films, and downloaded 4K content all commonly arrive as MKV. When you need the audio track separately — for transcription, study, reference, or DAW import — extracting to WAV gives you a clean uncompressed source without re-encoding.
Extract Now
Isolate the Audio Track for Editing or Transcription
MKV files can contain multiple audio tracks — commentary, language dubs, or director audio. Once extracted as WAV, you can import the track into any audio editor for cleanup, normalization, transcription, or remixing without dealing with the video container.

Frequently Asked Questions
Does the MKV file get uploaded to a server?
No. Extraction runs entirely in your browser using the Web Audio API. The MKV file is read from your local disk into browser memory and never sent to any server.
My MKV has multiple audio tracks. Which one does the extractor use?
The browser's AudioContext.decodeAudioData() decodes the first audio track it can decode in the MKV. For MKV files with multiple tracks, the default track (usually the first one) is extracted. If you need a specific track, use a desktop tool like FFmpeg or MKVToolNix to extract it directly.
Will AC3 or DTS audio inside my MKV work?
AC3 (Dolby Digital) and DTS are supported natively in some browsers (Safari on macOS, Edge on Windows) but not in others (Chrome, Firefox). If your MKV contains AC3 or DTS audio and extraction fails, try opening the page in Safari or use the Audio Extractor tool which may handle it differently depending on your OS.
Is there a file size limit?
There is no server-imposed limit since everything runs in your browser. Very large MKV files (several GB) may push against available browser memory. For typical clips up to a few hundred MB, extraction works without issue.
Can I extract audio from other video formats?
Use the MP4 to WAV page for MP4 files, the MOV to WAV page for QuickTime MOV files, or the general Audio Extractor which accepts any video format your browser can decode.
