How do you want to download it?
Turn any MP4 video into an MP3 audio file
You filmed a concert, recorded a lecture, saved a podcast episode as video, or you just want the music from a clip: you don't need the picture, only the sound. Klipa's MP4 to MP3 converter extracts the audio track from your video and gives it back to you as a clean MP3 — right in the browser, with nothing to install.
It's the same engine as our audio extractor, focused on the most common job: MP4 in, MP3 out. If your file is a MOV, AVI or WebM, it works too. And once you have your audio, you can transcribe it to text or remove background noise with the rest of the toolbox.
How to convert MP4 to MP3
Upload your MP4
Drag and drop your MP4 video or pick it from your device. Phone recordings, screen captures, downloaded videos — anything with an audio track works.
The audio is extracted
Our server separates the audio from the video and encodes it as MP3 (you can also pick WAV, AAC, OGG or FLAC before starting). Nothing is re-filmed or degraded on the way.
Save your MP3 file
Your MP3 is ready to play anywhere — phone, car, podcast app. Need to trim it first? Cut the video before converting, or clean up the noise for a clearer track.
Why convert MP4 to MP3?
Audio only, file 10× smaller
An MP3 keeps just the sound: a 200 MB video becomes a few MB of audio you can store and share easily.
Plays everywhere
MP3 is the most compatible audio format ever made — phones, cars, smart speakers, editing software.
More output formats
MP3 by default, but you can also export WAV, AAC, OGG or FLAC depending on what you need.
No watermark, ever
Audio files are never watermarked. What you hear in your video is exactly what you download.
MP4 TO MP3: USE CASES
Music and concerts
Keep the song from a video clip or a live performance you filmed, and listen to it like any track in your library.
Podcasts and interviews
Recorded an interview or a meeting as video? Convert it to MP3 to archive it light, share it, or turn it into text.
Lectures and courses
Turn recorded classes into audio you can replay while commuting — no screen needed, a fraction of the storage.
