Uncompressed audio extraction
WAV audio extraction
This page selects WAV automatically and writes decoded audio as uncompressed 16-bit PCM inside a WAV container.
WAV avoids another lossy compression step and is useful for editing, transcription and audio processing.
Uncompressed audio is much larger than MP3 or M4A. Long videos require more memory and storage.
The video is decoded locally in your browser and the WAV download is generated on your device.
Select one or more supported video files from your device.
WAV is selected automatically; bitrate controls are disabled because the output is uncompressed PCM.
Start conversion, keep the tab open, then download the generated .wav files.
WAV is well suited to editing, transcription, waveform analysis and workflows that expect PCM audio. The converter writes 16-bit little-endian PCM, a widely supported uncompressed format.
WAV does not restore quality missing from a compressed source. It avoids adding another lossy encoding step, but the result can only preserve the audio that was available in the video.
Common input containers include MP4, MOV, MKV, WebM, AVI, M4V, MPEG and 3GP. Codec compatibility still determines whether a specific file can be decoded.
Unlike MP3, WAV output does not use a selectable lossy bitrate. File size depends mainly on duration, sample rate, channel count and bit depth. Stereo WAV from a long video can require substantially more storage than compressed audio.
Use MP3 or M4A when compact sharing is more important. Choose WAV when editing compatibility and avoiding another lossy step matter more than size.
Local decoding and uncompressed output can use significant memory. Desktop devices generally handle long videos more reliably than phones. Close unused tabs, keep sufficient free storage and leave this page open until processing finishes.
PCM WAV is uncompressed. It avoids new lossy compression, but cannot recover detail already missing from the source audio.
PCM stores audio samples without MP3-style compression, so size grows quickly with duration, channels and sample rate.
No. Decoding and WAV generation run locally in the browser.
The bitrate choices apply to lossy encoders. This page writes uncompressed PCM audio instead.
Yes. PCM WAV is widely accepted by audio editors, transcription tools and production software.
