The fastest way to extract audio from a video file without installing anything is to use a free browser-based converter: upload the video, it strips the audio track and hands you back an MP3, and nothing is kept on the server afterward. ClearVoice’s audio extractor does exactly this, and it’s free with no account required.
Why extract audio from a video file?
- You recorded a podcast or interview on video (a Zoom call, a phone recording) but only need the audio.
- You want to pull a voiceover, a song, or sound effects out of a video clip.
- You're prepping a file for noise removal or editing, and audio-only tools are faster to work with than full video.
- You need a smaller file to send or upload somewhere that only accepts audio.
How to extract audio from a video, step by step
- Go to the audio extractor page.
- Click the upload box (or drag your video file into it) -- MP4, MOV, MKV, WebM and most other common formats work.
- Click "Process file." It usually takes a few seconds, depending on the video's length.
- Your browser automatically downloads the result as an MP3.
What video formats are supported?
MP4, MOV, MKV, WebM, AVI and most other common video containers all work -- the tool reads the file's audio track directly, so the specific container format rarely matters. Files are capped at 300MB and 30 minutes, which covers the vast majority of podcast episodes, lecture recordings and video calls.
Frequently asked questions
Is this actually free?
Yes -- no signup, no watermark, no limit on how many times you use it. There's no catch; it's a plain ffmpeg conversion running on our server, which costs us very little to offer for free.
Is my file stored or shared with anyone?
No. The uploaded video and the resulting audio file are both deleted from the server immediately after your download starts. Nothing is kept, logged, or used for anything else.
Will this reduce the audio quality?
The output is a high-quality variable-bitrate MP3 (roughly 190kbps), which is effectively indistinguishable from the source for speech and most music. If you need a lossless format, this particular free tool isn't the right fit -- it's built for the common case of "I just need the audio as an MP3."
One more thing worth knowing: none of these tools remove background noise -- they just cut, convert, join or measure audio as-is. If your recording still has fan hum, room echo, traffic or a noisy AC unit under the voice, run it through ClearVoice’s AI noise removal afterward -- upload the file, and it comes back clean.
