Convert video to audio in your browser and save the soundtrack as WAV or MP3. WAV is the pick for editing: a phone clip, a screen recording or a camera file becomes an uncompressed 16-bit soundtrack ready for a DAW, a podcast edit or a transcript. MP3 is the pick for listening, at about a seventh of the WAV’s size. This video to audio converter reads MP4, MOV, MKV and WebM, decodes the sound and nothing else, and runs on your own device, so the video is never uploaded. Several videos at once come back as one ZIP.
How it works
- Drop one video or a batch: MP4 and MOV from phones and cameras, MKV from screen recorders, WebM from browser recordings.
- Choose WAV for editing or transcribing, or MP3 for listening; MP3 is selected to start with. Set trim points if you only need part of the soundtrack.
- Convert and download the audio file, or one ZIP for a batch, each file named after the video it came from.
Questions
- How do I convert a video to WAV?
- Drop the video, switch the format to WAV and convert. The soundtrack is decoded and written as 16-bit PCM WAV, the plain kind every editor opens. It is not a byte-for-byte copy of the original track, which in most videos is compressed AAC, but it adds no compression of its own, so it is the best starting point for editing, mixing or transcription.
- What if the video has more than one audio track?
- The tool takes one: the track marked as the default, or the highest-bitrate one if none is, which is normally the track a player starts with. Commentary, second languages and other extra tracks are skipped. A video with no audio track at all is flagged as soon as you drop it, rather than turned into a silent file.
- Can I extract the audio from a screen or meeting recording?
- Yes, as long as the file is MP4, MOV, MKV or WebM and its sound is in a common codec such as AAC, Opus or MP3, which covers most meeting recordings, screen recorders and phone videos. Save it as WAV if it is going to a transcription or editing tool, or as MP3 at 128 kbps to keep a long call small, at about 1 MB per minute.
- Does my file get uploaded?
- No. The models and all processing run inside your browser on your own device. You can verify this yourself: open your browser’s DevTools, watch the Network tab, and process a file: there are no uploads. After the first visit most tools also work fully offline.
- Which formats can it read?
- Anything your browser can decode: MP3, WAV, M4A/AAC, OGG, Opus, FLAC and the audio track of MP4/WebM/MOV video. Output is MP3 or WAV, the two formats that open everywhere.
- Does converting to MP3 lose quality?
- MP3 is lossy, so some information is discarded, though at 192 kbps and above most people cannot hear the difference. WAV output is lossless and correspondingly larger. Converting MP3 to WAV does not restore quality that was already gone.
