About MP3 Compression Technology
MP3 (MPEG-1 Audio Layer III) is the most widely used audio format for music and podcasts. MP3 compression works by reducing the audio bitrate - the amount of data used per second of audio. Our tool uses the LAME encoder algorithm to efficiently reduce file size while preserving audio quality. The compression happens entirely in your browser, ensuring your audio files remain private.
