When to Extract Audio from Video
Podcast from video
Record your podcast on camera, extract the audio, and publish the MP3 to Spotify, Apple Podcasts, or any RSS feed — without a separate audio recording.
iPhone interview recordings
Extract audio from MOV files shot on iPhone. Convert to MP3 for easy sharing, or WAV for clean editing in GarageBand or Audacity.
Screen recording narration
Pull the voiceover audio from a screen recording and use it in a slide deck, e-learning module, or as a standalone audio guide.
Music from live video
Captured a live performance on your phone? Extract the audio and add it to your playlist or archive without keeping the large video file.
Meeting & lecture audio
Convert Zoom, Teams, or Google Meet recordings (.mp4) to MP3 for transcription, replay at 2× speed, or sharing with people who weren't on the call.
Music video audio
Have a music video or live performance download? Pull just the audio track and skip keeping the multi-gigabyte video file.
How Video to Audio Extraction Works
Video files like MP4 and MOV are containers — they hold separate video and audio tracks packaged together. Extracting audio means discarding the video track and keeping only the audio, which can then be saved as MP3 (compressed, smaller) or WAV (uncompressed, editing-ready).
Most video files already contain compressed audio (usually AAC). Converting that to MP3 involves one re-encode. At 192–320 kbps, the result is indistinguishable from the source for voice and most music. If you plan to edit the audio extensively, extract to WAV first to avoid compounding compression losses.
AudioUtils handles all of this in your browser using FFmpeg WebAssembly. Your video file never leaves your device — particularly important when the video contains sensitive content like private meetings, unreleased material, or personal recordings.

Frequently Asked Questions
What video formats can I extract audio from?
MP4 and MOV are supported — covering iPhone videos, Android recordings, camera footage, Zoom recordings, screen recordings, and most other common video formats.
Do I need to upload my video to a server?
No. AudioUtils runs entirely in your browser using WebAssembly. Your video file never leaves your device — nothing is uploaded or stored on any server.
Should I extract to MP3 or WAV?
Extract to MP3 for sharing, podcasting, or playback — smaller files, plays everywhere. Extract to WAV if you plan to edit the audio in a DAW — uncompressed, no re-encoding loss.
Does this work on iPhone video files?
Yes. iPhone records video as .mov or .mp4. Both work. Select the video from the Files app, iCloud Drive, or a shared link. Works in Safari on iOS 15.4+.
How large can my video file be?
Free tier supports files up to 20 MB (roughly 2–3 minutes of iPhone video). Pro ($9/month) handles files up to 500 MB — about 15–20 minutes of 1080p footage.
