Video to WAV Converter
Extract a video's audio as uncompressed WAV — the correct starting point for editing, restoration or re-mixing.
Convert with this tool
or choose a file from your device — it is processed in this tab and never uploaded
Accepted: MP4, WebM, MOV, MKV, AVI, M4V and other containers with an audio track
Files stay on your device. There is no upload, no queue and no watermark, so a conversion works even with the network switched off after the page has loaded.
Supported formats & processing
| Accepted input | MP4, WebM, MOV, MKV, AVI, M4V and other containers with an audio track |
|---|---|
| Produced output | WAV — 16-bit PCM, 24-bit PCM or 32-bit float |
| Processing | Web Audio API + canvas + native JavaScript encoders |
| Upload required | No — the file is read locally and never transmitted |
How to use this tool
- Add the videoThe audio track is located and decoded to PCM.
- Choose the bit depth16-bit for delivery, 24-bit for editing, 32-bit float for processing chains.
- Keep the sample rate at the source valueVideo audio is normally 48 kHz, which is exactly what editors want.
- ConvertUncompressed output means no psychoacoustic encoding step.
- Download the WAVExpect roughly 10 MB per minute at 16-bit stereo, 15 MB at 24-bit.
About this tool
When the audio from a video is going to be edited, MP3 is the wrong destination. Every encode discards information, and an editor that works on an already-compressed file has less to work with. WAV gives you the decoded samples in full, at the sample rate and bit depth you choose.
This tool decodes the video's audio track, renders it offline at your chosen rate and bit depth, and writes a proper RIFF/WAVE file. Because nothing is compressed, the result can be imported into any editor, processed repeatedly, and re-encoded later without cumulative loss.
Features
- Uncompressed PCM extraction — no generation loss at all
- 16-bit, 24-bit and 32-bit float WAV output
- Correct RIFF header with accurate block-align and byte-rate fields
- Channel count preserved from the source track
- Ideal for dialogue editing, restoration and re-mixing
- Native decoding for MP4, WebM and MOV containers
Frequently asked questions
Why is the WAV so much larger than the video?
Video is compressed in two dimensions; uncompressed audio is not compressed at all. One minute of 16-bit stereo at 48 kHz is about 11 MB — larger than many short video files.
Should I use 24-bit for dialogue editing?
Yes. 24-bit gives 144 dB of theoretical dynamic range, which means you can apply aggressive processing without the noise floor becoming audible.
Can I extract only part of the video's audio?
Convert to WAV here, then trim the WAV with the audio trimmer — that keeps the editing lossless until the final delivery encode.
What if the video has no audio track?
The decode will fail with a clear message. Check the video info checker to confirm whether an audio stream is present before extracting.
