Converting a video to MP3 extracts just the audio track, creating a much smaller file that plays on any device. Our tool uses FFmpeg on the server — the industry-standard audio and video processing library — to extract the audio and encode it as MP3 at your chosen bitrate.
Common uses: Extracting music from a music video, saving a podcast or lecture for offline listening, ripping audio from a screen recording, or creating an audio version of a video tutorial.
Bitrate guide: 320 kbps (High) is CD quality — indistinguishable from the source for most listeners. 192 kbps (Medium) is transparent to most people and half the file size. 128 kbps (Low) is adequate for voice content and small file size.
