How to Extract Audio from a Video (Video to MP3)
Updated 2026-07-15
To extract audio from a video, open the Extract Audio tool, drop in the video, choose MP3 (or WAV, FLAC, OGG), and save. The conversion happens entirely in your browser — the video is never uploaded — so a private lecture recording, a voice memo filmed as video, or an interview stays on your device.
When you'd want just the audio
- A talk, lecture or meeting recording you want to listen to like a podcast.
- Music or a voice-over you recorded as video and need as an audio file for editing.
- An interview headed for a transcription tool.
- A sound effect or clip you want to reuse in another project.
Extract step by step
- Open the Extract Audio from Video tool and drop in your file. You'll see its duration, size, and audio codec. (If the video has no audio track at all, the tool tells you straight away rather than producing an empty file.)
- Pick the output format — see the guide below.
- For MP3, choose a bitrate: 128 kbps for speech, 192 kbps as an all-rounder, 320 kbps for music you care about.
- Optionally toggle extract only a section and set start/end times (type 1:23 or plain seconds) to pull just the part you need.
- Hit extract, watch the progress, preview the result with the built-in player, and save.
Which format should you pick?
- MP3 — plays absolutely everywhere; the right default for listening, sharing and voice.
- WAV — uncompressed, sample-accurate; pick it when the audio is headed into an editor (Audacity, a DAW, a video editor). Big files.
- FLAC — lossless like WAV but roughly half the size; the archival choice.
- OGG — compact and open; good for the web and game engines.
A useful rule: pick lossless (WAV/FLAC) if you'll edit the audio further, lossy (MP3/OGG) if you'll just listen to or share it. Converting a lossy source to WAV doesn't add quality back — it just makes a bigger file.
iPhone videos, screen recordings and other sources
MOV files from iPhones, MP4/WebM screen recordings, and MKV downloads all work — the tool reads the container, finds the audio track, and re-encodes it to your chosen format on-device. If you also need the video itself in another format, run it through the Video Converter separately.
What about transcription?
If the real goal is text, you can skip the middle step entirely: the Transcribe Audio tool and the Podcast Show Notes generator both accept video files directly and transcribe them on-device with Whisper.
Privacy
Most "video to MP3" sites upload your file to their servers. This one doesn't: the Extract Audio tool demuxes and encodes in the tab using your browser's own media engine. No upload, no account, no length cap beyond your device's memory — and it works on phones.
