Extract audio from a video, free

Extract audio in three steps

Drop your video, pick a format (or keep the original), and download the audio. Your browser does all the work.

By default, nothing is re-encoded

The default choice, Original (no conversion), copies the audio track straight out of the video with no quality loss and no re-encoding: the same codec, the same bitrate, the exact audio that’s already in the file. It’s also the fastest option, because your browser only has to copy the stream, not convert it. The saved file gets the extension that matches the source audio, for example .m4a for most MP4 videos, or .opus / .ogg for many WebM files.

Or convert to any format

Want a specific format instead? Pick one from the menu and the audio is re-encoded to it, right in your browser:

• Lossy (smaller files): MP3, M4A (AAC), Opus, OGG (Vorbis), AC-3, E-AC-3, WMA
• Lossless / uncompressed: WAV, AIFF, FLAC, ALAC, WavPack, TTA

Converting always takes longer than keeping the original, and long videos take longer still. If you just need the audio out of the video, Original is usually the best pick. If you specifically want an MP3, our step-by-step guide to converting video to MP3 covers the settings.

Your file never leaves the device

Pulling the audio track out of webinar-recording.mp4 happens entirely on your laptop or phone: the video is read from drop to download, and not a byte leaves. It’s the same in-browser extraction Hushscript runs before transcription, so only you ever hold the audio.

About large files and file size

There’s no fixed size cap, but everything runs inside your browser tab, using your device’s memory; no server does the work. That’s what keeps your video private, and it’s also the real limit: a very large video can run out of memory and fail, more easily on phones or older machines.

• Original (no conversion) is the lightest and fastest, so it handles the biggest videos best.
• Converting uses more memory and time, especially for long videos or lossless formats.
• Lossless and uncompressed formats (WAV, AIFF, FLAC, …) produce much larger files than MP3, M4A or Opus; a few minutes of WAV can be tens of megabytes.

If a big video fails, choose Original, or shrink the video first, then try again.

Skip the step if you only need text

Converting a video just to transcribe it? You can skip that: Hushscript takes the original video, extracts the audio itself, and returns a speaker-labeled transcript. The first 30 minutes are free.
