MP4 TO MP3

Convert MP4 to MP3

Pull the audio out of a video and save it as an MP3. Drop in an MP4 — a music video, a screen recording, a phone clip — and the sound track is re-encoded to MP3 right here in your browser. It is free, there is no sign-up, and your file is never uploaded.

Free, no sign-up. Converted in your browser — your file is never uploaded.

How it works

Three steps, all in your browser

01

Drop your MP4

Drag the video in or tap to pick it. The converter reads the audio track inside the MP4 — usually AAC — and ignores the video.

02

Convert in your browser

The audio is decoded and re-encoded to MP3 on your own device, at the bitrate you choose. Nothing is uploaded to a server.

03

Download the MP3

A Download button hands you the finished MP3. Convert another file straight away — there is no queue and no limit per session.

Why convert MP4 to MP3

When the audio is all you need

A lecture you recorded, a song stuck inside a music video, a podcast you filmed — sometimes you only want the sound. An MP3 plays everywhere, is small enough to email, and drops into any playlist or editing app. Built for songs and clips up to 30 minutes or 500 MB, this converter strips the audio out without re-touching the video itself.

Need lossless audio instead? Convert MP4 to WAV for an uncompressed file, or open the free audio converter to pick any output format.

FAQ

Frequently asked questions

How do I convert an MP4 to MP3?
Drop your MP4 onto the converter and choose a bitrate. The audio track is decoded and re-encoded to MP3 right in your browser, then a Download button appears. There is nothing to install and no account to create.
Is my file uploaded?
No — conversion happens entirely in your browser. Your file never leaves your device.
Does this keep the video?
No — you get just the audio as an MP3. The MP4 you dropped in is left untouched; the converter only reads its sound track and writes a new MP3 file.
What bitrate does the MP3 use?
You can pick 320, 192, or 128 kbps. 320 kbps is the default for the cleanest result; lower bitrates make a smaller file that is easier to share or email.
How big a file can I convert?
The converter is built for songs and clips up to 30 minutes or 500 MB. That covers music videos and most recordings; a feature-length film is too large to process in the browser.
