How do I check the WAV before I save it?
To convert video to WAV for free, choose an MP4, MOV, or WebM above, keep WAV selected, and select Extract audio. Your browser writes an uncompressed WAV at the video’s own sample rate. Play the WAV on this page before you download it; the video never leaves your device.
Play it here first
A player appears under the download button. Check the start and the end before you take it into an editor.
Spot noise before you edit
If the quiet parts of the WAV carry a steady hum or wind, the page says so and offers a free noise removal preview.
Why convert video to WAV?
WAV is what audio editors, mixers, and noise tools work in best. Converting video to WAV gets the soundtrack into that form in one step.
Edit the audio in a DAW
Audacity, Audition, Logic, and Reaper all edit WAV without first decoding it.
Fix the sound, then put it back
Clean or level the WAV, then lay it under the original picture in your video editor at the first frame.
Send a mixer or transcriber a lossless file
A sound engineer or a careful transcription service often asks for WAV, not MP3.
Remove wind or traffic
Noise removal reads any format, and a WAV keeps the cleaned result lossless until the final export.
Remove background noise from audioHow big is a WAV from a video?
WAV is uncompressed, so its size depends only on length, sample rate, and channels. The quality is the same as the video’s soundtrack.
| Length | Stereo, 44.1 kHz | Stereo, 48 kHz |
|---|---|---|
| 1 minute | About 10 MB | About 11 MB |
| 10 minutes | About 100 MB | About 115 MB |
| 60 minutes (the limit here) | About 600 MB | About 690 MB |
Why use EraseNoise instead of an upload site?
It decodes the soundtrack and writes a standard WAV, with nothing added and nothing uploaded.
Nothing is uploaded
The browser reads the video and writes the WAV, so private footage stays on your device.
The video’s own sample rate
Phone and camera video is usually 48 kHz. When you convert video to WAV here, the WAV keeps that rate and the same channels, so it lines up with the picture.
Large videos are fine
Only the audio is decoded. A 2 GB 4K file works because the picture is skipped.
Free with no account
No sign-up, no watermark, and no daily cap.
Why is it faster than uploading the video?
When you convert video to WAV here, there is no upload of the video and no download of a large WAV. Both happen on your device.
No upload wait
Online tools that convert video to WAV upload the whole file. Here a 1 GB video stays put and only the sound is decoded.
No big download
A 600 MB WAV is written straight to your disk instead of coming back over the network.
No editor needed
You do not need to open a project to convert video to WAV for one clip.
Which videos can I convert to WAV?
Convert video to WAV from files up to 2 GB with up to 60 minutes of sound.
MP4, MOV, M4V, or WebM
iPhone and Android video, GoPro and camera files, screen recordings, and editor exports.
Up to 60 minutes of sound
The WAV is built in memory. For a longer video, save the sound as M4A or MP3 instead.
MP4 to WAV and MOV to WAV
Both are the same job here. Choose the file and WAV is already selected.
MKV from OBS
Remux it to MP4 first in OBS with File, Remux Recordings.

Frequently asked questions
How do I convert video to WAV for free?
Open this page, choose the video, keep WAV selected, and select Extract audio. Your browser does the work, so it is free, needs no account, and adds no watermark.
How do I convert MP4 to WAV?
The same way: choose the MP4 and extract. The WAV keeps the MP4’s sample rate, usually 48 kHz, and its channels.
Is a WAV from a video better quality than the video’s audio?
It sounds the same. Converting video to WAV decodes the compressed soundtrack into uncompressed audio, which stops further loss while you edit but cannot add detail.
Is my video uploaded?
No. The video is read and the WAV is written in your browser. Nothing is sent to EraseNoise or anyone else.
Is there a length limit?
Yes, 60 minutes of sound, because the WAV is built in your browser’s memory. For longer videos, save M4A or MP3.
Will the WAV stay in sync with the video?
Yes. It starts at the first frame and keeps the same length, so it lines up when you place it at the start of the clip.
