MP3 for broad playback
Re-encode the first audio track as MP3 with selectable bitrate, sample rate and channels.

How to extract audio from a video
- 1
Choose a compatible video
Select one supported MP4, MOV or WebM file that contains an audio track.
- 2
Choose MP3 or Original audio
MP3 re-encodes the track and offers optional start/end times in Advanced settings when the video length is available. Original audio copies the complete compatible AAC or Opus track; trimming is unavailable in that mode.
- 3
Extract and save
Run the local extraction and download the M4A, Ogg Opus or MP3 result.
Choose the output that fits the job
Original audio without another encode
Stream copy compatible AAC or Opus audio so extraction adds no new re-encoding loss.
Private browser-local workflow
Probe, extraction, preview and download remain on your device and require no account.
Follow the iPhone file and download stepsVerified extraction matrix
- MP4 or MOV with AAC: MP3 re-encode or original AAC copied into M4A.
- WebM with Opus: MP3 re-encode or original Opus copied into an Ogg .opus file.
- The first audio track is used; V1 does not include a track selector.
- Original audio is available only when the detected codec is AAC or Opus.
Audio extraction use cases
- Keep the original compressed audio from a compatible recording without another encode.
- Create a widely playable MP3 from an AAC or Opus video track.
- Remove the video track from a presentation, interview or screen recording you can use.
Stream copy and audio containers
M4A contains copied AAC audio
For a detected AAC track, Original audio uses stream copy and places those same compressed audio packets in an M4A audio container.
The .opus result uses Ogg
For a detected Opus track, Original audio copies the track into an Ogg container with the .opus extension.
Original audio versus MP3
Original audio uses stream copy, so it avoids additional re-encoding loss. It does not make an already compressed source lossless.
MP3 mode re-encodes audio and exposes bitrate, sample-rate and channel controls for compatibility needs.
The output is determined from the actual first audio track codec, not from the video filename or container extension.
Audio extraction limits
- Only the first audio track is extracted; selecting another track is outside V1.
- Not every audio codec supports Original audio. Unsupported codecs return a clear error and remain available for MP3 retry.
- Files without an audio track cannot produce an output.
- The soft limit is 500 MiB on desktop and 200 MiB on mobile, while available browser memory can be lower.
Frequently asked questions
What is the difference between MP3 and Original audio?
MP3 re-encodes the audio using the selected settings. Original audio stream-copies a compatible AAC or Opus track without another encode.
Is Original audio lossless?
No. Stream copy preserves the existing compressed track without adding re-encoding loss, but it does not make AAC or Opus lossless.
Why does AAC download as M4A?
M4A is the audio container used here for the copied AAC track. The AAC packets are not converted to MP3 in Original audio mode.
What happens when Original audio is unsupported?
The converter keeps the file selected and asks you to choose MP3. It does not silently fall back or disguise a re-encoded file as original audio.
