MP4 to MP3 without uploading
MP4 is the most common video format — phone videos, screen recordings, downloaded clips and video-call recordings are almost always MP4. Its audio is usually AAC, which this tool decodes and re-encodes as MP3 so it plays on every device and car stereo.
Which bitrate to choose
A higher bitrate means better quality and a bigger file:
- 128 kbps — speech, lectures, podcasts (about 1 MB per minute)
- 192 kbps — recommended for most music (about 1.4 MB per minute)
- 320 kbps — best quality for music (about 2.4 MB per minute)
Frequently asked questions
Does it work on iPhone and Android?
Yes. Open this page in Safari or Chrome, choose the MP4 from your photos or files, and the MP3 is saved to your downloads.
Is the audio quality the same as the video?
At 192 or 320 kbps the MP3 sounds the same as the video’s soundtrack to almost everyone. Choose WAV if you need a lossless copy.
Can I convert a YouTube link?
No — this tool converts video files you already have on your device. It does not download from YouTube or other websites.
