# How to Convert MP4 to MP3 (Konverter MP4 til MP3) on Any Device Canonical: https://filevale.com/guides/konverter-mp4-til-mp3/ Updated: 2026-11-02 > Convert MP4 to MP3 (konverter MP4 til MP3) in your browser on Windows, Mac, iPhone or Android. Pick the quality, convert several files, nothing uploaded. To convert MP4 to MP3 (konverter MP4 til MP3), open Filevale's MP4 to MP3 Converter, drop in your video and click **Extract audio from**; the MP3 is made on your own device. It works in any modern browser on Windows, Mac, iPhone, Android or a Chromebook, with nothing to install. Below are the steps, which quality to pick, and what to do on each kind of device. ## Convert MP4 to MP3 in your browser [Open MP4 to MP3 Converter](https://filevale.com/mp4-to-mp3/) 1. Open [MP4 to MP3 Converter](/mp4-to-mp3/) and drop your MP4 or M4V file on the page, or click to browse. You can add several files at once. 2. Adjust the quality if you like, then click **Extract audio from**. Everything happens on your device. 3. Download the MP3 file. If you converted a batch, you can download them all together as one ZIP. The converter keeps the audio track and saves it as MP3 at up to 192 kbps. It runs on a WebAssembly build of FFmpeg inside your browser, so your video is not uploaded to a server. That matters for recorded meetings, interviews and family videos. The first time, the converter engine (about 30 MB) is downloaded once and then cached. After that, a short phone clip usually takes seconds; longer files depend on your device's processor. If the result isn't what you wanted, change the options and run it again on the same file. ## Which quality should you pick? MP3 is the most compatible audio format, but it is lossy. For most listening, 128–192 kbps sounds good. Use the higher setting for music and the lower one for speech, such as lectures, podcasts or voice recordings, where a smaller file is more useful than extra detail. Converting can't add quality that wasn't there. If the audio in the video is quiet or noisy, the MP3 will be too. ## Your video isn't an MP4? [Open Video to MP3 Converter](https://filevale.com/video-to-mp3/) Videos from other sources often come as MOV (iPhone and Mac cameras), WebM, MKV or AVI. [Video to MP3 Converter](/video-to-mp3/) takes MP4, MOV, WEBM, MKV, AVI and M4V files and works the same way: drop the file, click **Extract audio from**, download the MP3. Both converters can also save the sound as M4A, WAV, FLAC, AIFF, CAF or OGG instead of MP3, which is handy if an editing app or a school or work submission asks for a specific format. ## On Windows, Mac, iPhone and Android - **Windows**: open the converter in Edge or Chrome and drop the file. There is nothing to install. - **Mac**: QuickTime Player can save a video's sound with *File → Export As → Audio Only*, but the result is an M4A file, not MP3. To get an MP3, use the browser converter directly, or turn the M4A into MP3 afterwards with [Audio Converter](/audio-converter/). - **iPhone and iPad**: the easiest route is the free Filevale iPhone app from the App Store, which has the same kind of tools on your device. If you would rather not install anything, the converter works in Safari: tap the drop area and pick the video from Files. - **Android**: open the converter in Chrome, tap the drop area to pick the video, and save the MP3 back to your phone. ## Good to know - Filevale can't trim or edit video, so the MP3 contains the whole audio track. If you only need part of it, cut the clip in your phone's or computer's own video editor first. - Need the MP3 even smaller to send by message or email? [Compress Audio](/compress-audio/) makes audio files small enough to send. - For more ways to pull sound out of a video, see [How to Extract Audio From a Video](/guides/mp4-to-mp3-extract-audio/), or browse all [video and audio tools](/video-audio-tools/). ## Frequently asked questions ### Is my video uploaded when I convert MP4 to MP3? No. The MP4 to MP3 Converter runs entirely in your browser, so the video never leaves your device. That makes it safe for private and confidential recordings. ### Can I convert several MP4 files at once? Yes. Add several files in one go, convert them, and download the MP3s one by one or together as one ZIP. The tool is free and adds no watermarks. ### Why is the MP3 so much smaller than the MP4? The MP4 holds both picture and sound, and the picture takes up most of the space. The MP3 keeps only the sound, and as a lossy format at 128–192 kbps it stays compact while sounding good for most listening.
