MP4 to MP3 converter

By using the service, you accept the Terms of Use and the Privacy Policy

Extract the sound from an MP4 video and save it as MP3 — for a player, a phone or editing. The converter works in the browser, with no software to install and no sign-up.

How to convert MP4 to MP3

Click “Select files” or drag an MP4 video into the box.
Make sure MP3 is selected on the right and choose the quality.
Click “Convert” — the MP3 will be saved to the Downloads folder.

MP3 quality

320 kbps — studio quality.
256 kbps — high quality.
192 kbps — standard quality, selected by default.
128 kbps — compressed quality, the smallest file.

What extracting sound from a video is good for

Lectures, podcasts and interviews are easier to listen to as audio — on the road or with the screen off.
Music from clips and concerts can be saved for a player or a phone.
Ringtones, voice-overs and sounds for editing — an MP3 is easy to trim in any audio editor.

Which bitrate to choose

For speech — podcasts, lectures, voice-overs — 128 kbit/s is enough: the file is small and the words are clear. For music 192 kbit/s or higher is better, and 320 kbit/s is worth it if you will process the sound or play it on good speakers.

An MP3 takes up roughly this much per minute of sound:

128 kbit/s — about 1 MB.
192 kbit/s — about 1.4 MB.
256 kbit/s — about 1.9 MB.
320 kbit/s — about 2.4 MB.

Will the sound be better at 320 kbps?

No, conversion cannot add quality that isn't in the video. If the clip's sound was recorded at 128 kbps, choosing 320 kbps only makes the file bigger.

Can I save the sound as M4A or WAV?

Yes. The format list next to the file includes M4A, AAC, WAV, FLAC, OGG, OPUS and more.

Does the converter work on a phone?

Yes, on Android and iPhone in any modern browser. The finished file goes to the Downloads folder.

How fast is the sound extracted?

Usually from a few seconds to a few minutes: the time depends on the file size and how busy the service is. The progress is shown on the page.

Can I extract the sound from several videos at once?

Yes, select several files at once — each up to 1 GB. They are converted at the same time, and each video gets its own MP3.

Formats

From video (MP4, MOV, MKV, WEBM, AVI, FLV, M4V, MPEG, VOB, 3GP, WMV) — to MP4, MOV, M4V, AVI, WEBM, FLV, MPEG, VOB, GIF and to audio: MP3, M4A, AAC, WAV, FLAC, AIFF, OGG, OPUS, WMA, MP2, AC3.
From audio (MP3, M4A, AAC, WAV, FLAC, AIFF, OGG, OPUS, WMA, MP2, AC3) — to MP4 with a black background and to other audio formats.
From GIF — to MP4.

Limits

You can select several files at once, each up to 1 GB. Files are converted at the same time.
Video length is not limited — only the file size matters, up to 1 GB. H.264 video is repacked into MP4, MOV, M4V and FLV in seconds.
A GIF is made from the whole video: 8 frames per second, 360 pixels wide. WAV, FLAC and AIFF — up to 1 hour of audio (about 10 MB per minute).

File safety

The uploaded file is used only for the conversion and is never shared with anyone. The original file is deleted right after processing. The converted file is kept for 24 hours — during that time you can download it again — and is then deleted automatically.
