Why convert MP4 to MP3?
MP4 video files contain both video and audio tracks. When you only want the audio — for example, when saving music from a concert recording, extracting podcast audio from a video interview, or preparing audio for listening while driving — converting MP4 to MP3 strips the video and keeps only the sound. MP3 files are typically 10× smaller than MP4 videos, making them ideal for portable audio players, smartphones, and limited storage.
How to convert MP4 to MP3
Drop your MP4 video into Breklo and choose audio quality: 128 kbps for voice content, 192 kbps for general music, 320 kbps for high-fidelity audio. Our MP4 to MP3 converter uses the Web Audio API to decode the video and the LAMEjs encoder to produce MP3 output. Download your converted audio file in seconds. The conversion preserves audio quality with no degradation beyond the chosen MP3 bitrate.
