Your browser is too old for this tool
It can’t read or create audio. Update Chrome, Edge, Firefox, or Safari and try again.
Your browser doesn’t include audio WebCodecs, so its own decoder is used. It works the same with MP3, WAV, M4A, and FLAC; very long audio may take longer, and OGG isn’t available.
You can drag more files into the box above.
What do you want to get?
To create M4A (AAC), your browser downloads a ≈ 250 KB encoder once, only if it doesn’t include one. On a mobile connection this can take a few seconds.
More options
Raises or lowers the volume so the loudest point ends up close to the maximum, without distorting.
This file has several audio tracks (for example, different languages).
Trim (optional)

How to use it
- Drop your video into the box or select it from your device. You can load up to 20 videos at once.
- Choose “Convert” to get an MP3, WAV, OGG, or M4A, or “Lossless” to copy the original audio without re-encoding it.
- If you only want a section, open “More options” and type the start and end times. If the video has several audio tracks, you can choose which one to extract there.
- Select “Extract audio,” listen to it, and download it. If you loaded several videos, they download together in a ZIP.
Frequently asked questions
Is my video uploaded to a server?
No. The audio is separated inside your browser, on your own device. The video never leaves it, so you can work with private recordings safely.
How do I turn an MP4 video into an MP3?
Load the video, leave “Convert” selected with MP3, and select “Extract audio.” At 192 kbps the sound is very good for music; for speech, 64 or 96 kbps is enough and the file ends up much smaller.
What does “Lossless” mean?
The audio in a video is already compressed. This option copies it as is into a new file without compressing it again: it is almost instant and loses no quality. The format depends on the original: AAC audio is saved as M4A, Opus or Vorbis as OGG, and MP3 as MP3.
What happens if the video has several audio tracks?
With a single video, the tool lets you pick the track in “More options,” for example the language. With several videos, the main track of each one is used.
Why does it say my browser can’t read the audio?
Some browsers don’t include every codec. If that happens, try the “Lossless” option, which copies the audio without needing to decode it, or open this page in a recent version of Chrome, Edge, or Safari. If the video has no audio, the tool tells you.
Is there a size limit or a watermark?
There is no watermark and no artificial limit. You can load videos of up to 4 GB each; because they are read from your device, very large files may take longer or run out of memory.
Convert or copy: which one to choose
A video stores its sound already compressed in a format such as AAC, MP3, or Opus. If you copy it, the result is identical to the original audio and is created in seconds, no matter how long the video is. It is the best choice if you want the exact quality. If you prefer a different format, for example an MP3 for an old player, convert it: the audio is decoded and compressed again.
Video formats you can use
- MP4, M4V, MOV, and 3GP: the ones that come from phones and cameras.
- MKV and WebM: common in downloads and screen recordings.
- Audio files: you can also load an MP3, M4A, WAV, OGG, or FLAC and convert it.
Tips
- For a song, use MP3 at 192 kbps or M4A. For a lecture or a call, 64 kbps is enough.
- If the recording is quiet, turn on “Normalize volume” in More options.
- To keep just a section, type the start and end times or use the audio cutter afterward.
About the encoders
MP3 files are created with an encoder based on LAME, compiled to WebAssembly (LGPL license). If your browser can’t create M4A (AAC), the AAC encoder from FFmpeg is used, also in WebAssembly (LGPL license), and FLAC files are created with libFLAC (BSD license). Each one is downloaded only when you choose that format and runs on your device.
