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

                

                    
Step 1
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.


Step 2
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.


Step 3
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.

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.

No watermark, ever

                        
Audio files are never watermarked. What you hear in your video is exactly what you download.

MP4 to MP3 — FAQ

                

                    
Is the MP4 to MP3 conversion free?
The first try is free, with no sign-up.
Does converting to MP3 lose quality?
The audio is encoded to high-bitrate MP3, which is transparent for speech and near-transparent for music. If you need the exact original track, choose WAV or FLAC (lossless) instead.
Can I choose another format than MP3?
Yes — before starting the conversion you can pick MP3, WAV, AAC, OGG or FLAC.
Does it work with formats other than MP4?
Yes. MOV, AVI, MKV, WebM and FLV videos are accepted too — the tool takes the audio track from any of them.
Is there a watermark on the audio?
No, never. A watermark makes no sense on audio: your file is delivered exactly as extracted.
Is my video kept on your servers?
Files are deleted automatically.
Can I extract just one part of the video?
Convert the whole file here, or cut your video first to keep only the segment you want, then convert that part to MP3.
