About the MP4 to MP3 Converter
Convert MP4 to MP3 online for free, with no account and no watermark. Sometimes you only need the audio track, a GIF or still frames from the video, so switching to MP3 is the quickest way to get MP3 audio that plays everywhere for music, podcasts, ringtones and audio that must play on any device.
Audio and video are processed by FFmpeg compiled to WebAssembly, the same open-source engine behind VLC and HandBrake, running inside your browser tab. Because everything happens on your own device, your videos are never uploaded, stored or seen by anyone else, which makes it safe for family videos, client footage and private recordings.
What to expect: only the soundtrack is kept and encoded as MP3; the processing engine (about 30 MB) is downloaded once and then cached by your browser.
How to use the MP4 to MP3 Converter
- Click "Choose files" or drag your MP4 videos onto the box. You can add several at once.
- Choose the MP3 bitrate: 128 kbps for speech, 192 kbps for music or 320 kbps for the best quality.
- Press "Convert to MP3". The conversion runs on your device and shows its progress.
- Download each MP3 file, or use "Download all (ZIP)" when you converted several.
- Open the result in every phone or car stereo to check it; your original MP4 is never changed.
Tips & benchmarks
- 192 kbps is transparent for most listeners; use 128 kbps for speech and podcasts and 320 kbps for music archives.
- MP4 is lossless and MP3 is not, so keep your original MP4 as the master copy and use the MP3 for sharing.
- Very large videos (over about 1 GB) may exceed the memory of a phone browser; trim them first with our Trim Video tool.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the MP3 to a website or government portal.
Frequently asked questions
How do I convert MP4 to MP3?

Yes. Add as many MP4 files as you like; they are converted one after another and you can download them individually or together as a ZIP.
Does it work on iPhone, Android and Mac?
Yes. The converter works in any modern browser, including Chrome, Safari, Edge and Firefox, on Android, iPhone, iPad, Windows, macOS and Linux. No app is needed. The audio and video engine is a larger download the first time, so Wi-Fi is recommended.
What is the difference between MP4 and MP3?
MP4 (MPEG-4 Part 14) is a video container (usually H.264 + AAC) best suited to sharing on WhatsApp, Instagram and YouTube and playing on any device. MP3 (MPEG-1 Audio Layer III) is a compressed audio best suited to music, podcasts, ringtones and audio that must play on any device.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
Can I convert MP4 to MP3 from a link?
No. The converter works on video files stored on your own device. Save your video first (only download content you have the rights to), then convert it here.
