01Why this extractor
Just the audio, please.
Four reasons students, podcast editors, and recruiters reach for this page when only the sound matters.
- 01
MP3, WAV, or M4A on the way out
MP3 for sharing, WAV when nothing's allowed to be lossy, M4A when you want AAC quality at a smaller size. Pick once, done.
- 02
FFmpeg, in your browser
WebAssembly runs the same FFmpeg the pros use. Audio extraction is faster than the video's runtime on most laptops.
- 03
Sensible bitrates
MP3 and M4A export at 192 kbps — high enough that speech and music both sound clean without the file ballooning.
- 04
Recording stays on your device
Lecture recordings, podcasts, meeting captures — nothing is uploaded. We never see the file you're pulling audio from.
02How it works
Three steps from video to audio.
- Drop videolecture.mp4412 MB · 1:24:10
Step 1Drop your video
Drag in an MP4, MOV, WebM, MKV, AVI, or M4V up to 500 MB. You can also drop an existing audio file if you just want to convert it.
- FormatMP3WAVM4A
Step 2Pick the audio format
MP3 for compatibility, M4A for slightly smaller files at the same quality, WAV when you'll edit further or need lossless.

Step 3Download the audio
Click Extract. The audio downloads with the original filename — no upload spinner, no progress bar after the click.
03Use cases
When the sound is the point.
A lot of video is really audio with pictures. Pull the audio out and the file gets simpler in every direction.
Listen to a recorded lecture
Skip the visuals. Pull the audio out of a 90-minute Zoom recording and play it back on a walk like a podcast.
lecture.mp4 → lecture.mp3Podcast from a video interview
Recorded the interview over Zoom or Riverside? Strip out the audio for the podcast version while the video goes to YouTube.
interview.mov → episode.m4aSave the soundtrack of a clip
Heard a great piece of background music in a video? Extract the audio to identify it or use it in your own edit.
clip.mp4 → soundtrack.wavTranscript prep
Transcription services often take audio cheaper than video. Convert to MP3 first, upload to your transcriber of choice.
meeting.mp4 → meeting.mp3Voice memos as M4A
Pull the voice track out of a video memo and save it in the format your audio editor or phone prefers.
Memo.mov → memo.m4aAudio for a music app
Want to listen to a recording offline? MP3 imports into every music app on every device — Spotify local files, Apple Music, the lot.
performance.mp4 → MP3
04Supported outputs
Pick the audio format.
Three honest options for three honest jobs: share, edit, or archive.
- MP3
Extract to MP3
Universal lossy format at 192 kbps. Plays in every music app, every browser, every car stereo.
- M4A
Extract to M4A
AAC inside an MP4 container. Slightly smaller than MP3 at the same quality.
- WAV
Extract to WAV
Uncompressed PCM. Larger files, but lossless for editing or archival.
- Audio
Convert audio formats
Already have audio in one format and need another? Drop it in and convert between MP3, WAV, and M4A.
05Quick tips
Pick the right format.
Habits that save you a re-export when the destination doesn't like what you handed it.
- 01
MP3 is the safe default
If you don't know what to pick, pick MP3. Every app and device plays it, the bitrate is set to a clean 192 kbps, and the file size is reasonable.
- 02
WAV for editing, MP3 for sharing
If you're about to mix, edit, or process the audio, go WAV — no quality loss to compound. If you're just listening or uploading, MP3 is fine.
- 03
Trim first if you only want a piece
Need just the chorus or the opening monologue? Trim the video first, then extract — the audio output is smaller and ready to use.
- 04
M4A is the smallest at the same quality
If file size matters and your destination supports it, M4A is ~10-15% smaller than MP3 at the same audible quality.
06Loved by
Students, editors, and recruiters use it weekly.
Lectures are recorded as MP4 but I want them as audio on my commute. Extract to MP3, AirDrop to my phone, done. Saves the data plan too.
Video interviews from Riverside come out as MOV. I extract the WAV, drop it in my DAW, edit normally. Free, no upload to wait for.
I extract the audio from candidate Zooms to get a transcript made. MP3 at 192k is fine for transcription and the file uploads in seconds.
07Questions
Audio extraction, plainly answered.
What people check before extracting their first MP3. Anything missing? hello@wirelogs.com.
01Which input formats work?
Any common video format: MP4, MOV, WebM, MKV, AVI, M4V. You can also drop in an existing audio file (MP3, WAV, M4A) if you just want to convert between audio formats.
02What's the difference between MP3, WAV, and M4A?
MP3 is the universal lossy format — small files, plays everywhere. WAV is uncompressed and lossless — much bigger files, but quality stays exact. M4A wraps AAC inside an MP4 container — slightly smaller than MP3 at the same quality.
03What bitrate does the output use?
MP3 and M4A export at 192 kbps, which is the sweet spot for clean-sounding voice and music. WAV is uncompressed, so bitrate isn't relevant — it stores raw 16-bit PCM samples.
04Will the audio quality drop?
Lossy outputs (MP3, M4A) lose a small amount of detail during encoding. At 192 kbps the difference is inaudible for the vast majority of listeners. WAV is lossless if you need exact preservation.
05What's the max file size?
500 MB per input. Most videos people want to extract audio from fit easily under that. Larger files? Trim them down first or split before extracting.
06How long does extraction take?
Much faster than the video's runtime — usually a couple of minutes for a one-hour file. WAV is fastest (no encoding work), MP3 and M4A slightly slower.
07Is the tool free?
Yes. No usage cap, no watermark, no premium plan, no sign-up.
08Does my video upload anywhere?
No. FFmpeg runs in your browser via WebAssembly. The video stays on your device, which keeps personal recordings, lectures, and meetings private.
