Extract audio from video

Save just the audio from an MP4, MOV, MKV, WebM or AVI as MP3 or WAV, with an optional start and end time.

    Drop MP4, MOV, MKV, WebM, AVI and other video files here or choose files.

    • Up to 500MB and 60 minutes per file
    • Up to 10 files at a time
    • AVI only with MP3 or PCM audio. MKV with AC-3 or DTS audio does not work

    MP3 is small and plays everywhere. WAV is uncompressed, which makes it better for editing but much larger.

    192kbps is enough for music. Use 128kbps for lectures and call recordings, 320kbps for a music archive.

    Mono merges left and right into one channel and reduces the file size (WAV drops by half). Good for voice recordings.

    You are unlikely to hear a difference either way. Pick 48kHz if the audio is going back into a video editor.

    Leave blank to start from the beginning. Write 90 or 1:30.

    Leave blank to go to the end. With several files, the same range is applied to each.

    Files never leave this device. Privacy policy

    How it works

    Choose a video, pick MP3 or WAV, and click Convert. The tool pulls out the audio and saves it. It accepts MP4, MOV, WebM, MKV and some AVI files.

    To keep only part of it, enter a start and end time. For example, 1:30 to 2:45 saves just that 1 minute 15 seconds.

    Things to know

    The browser decodes the audio itself, so codecs it does not recognize, such as the AC-3 and DTS audio common in movie files, cannot be extracted. The tool tells you when that happens.

    Long videos use a lot of memory, so the limit is 60 minutes. If a large file stalls on a phone, try it on a computer.

    Frequently asked questions

    Can I extract only part of the video?

    Yes. Enter a start and end time such as 90 or 1:30, and only that range is saved. Leave both blank for the whole file. For points past one hour, write 1:02:30.

    Should I pick MP3 or WAV?

    For listening or sharing, MP3 at 192kbps is small and plays everywhere. If the audio is going back into a video or music editor, WAV is better because it does not degrade further. Stereo WAV is about 10 to 11MB per minute.

    It says the file has no audio track.

    The video file contains no audio data at all. It was recorded muted, or exported from an editor with the audio removed. If you can hear sound when you play it and still get this message, try again in Chrome on a desktop.

    Are my files uploaded to a server?

    No. Decoding and converting happen entirely in this browser, and the file never leaves your device. The result disappears when you close the page, so use the save button to download it.
