A quick explanation
MP4 vs MP3: What is the difference?
MP4 is a multimedia container that can hold video, audio and subtitles. MP3 is an audio-only format built for broad compatibility and smaller file sizes.
Converting MP4 to MP3 removes the video track and creates audio that is easier to store, share and play on phones, computers, car stereos and MP3 players.

MP4 to MP3 converter FAQ
Everything you need to know before converting your video.
Is this MP4 to MP3 converter free?
+
Yes. You can convert MP4 videos to MP3 without creating an account or installing software.
Are my MP4 files uploaded to a server?
+
No. The conversion runs locally in your browser, so your files stay on your device and are not stored on our servers.
Is there a file-size limit?
+
There is no fixed server upload limit because files are processed on your device. The practical limit depends on your browser, available memory and device performance.
Can I batch convert multiple MP4 files?
+
Yes. Add multiple MP4 videos to the queue and download the finished MP3 files when processing is complete.
Does converting MP4 to MP3 reduce audio quality?
+
MP3 is a lossy format, so some information may be removed during encoding. Selecting 192 or 320 kbps keeps the difference difficult to notice for most listening.
What is the best bitrate for MP4 to MP3?
+
Use 128 kbps for speech, 192 kbps for general listening and 256–320 kbps for music. The ideal setting depends on the source audio.
Why is my converted MP3 larger than expected?
+
Output size depends on audio duration and bitrate. A bitrate higher than the source can create a larger file without improving quality.
Can I convert MP4 to MP3 on iPhone or Android?
+
Yes. Open the converter in a supported mobile browser, choose a video and save the converted MP3 when it is ready.
Can I turn MP4 into MP3 by changing the extension?
+
No. Renaming .mp4 to .mp3 does not remove the video or convert its audio. The file must be processed by a real converter.
