About MP4 to MP3 Converter

Video files are large containers carrying both a video stream and one or more audio tracks. When only the audio is needed — for a podcast source, a lecture recording, or an archival copy — stripping the video track reduces file size by 90% or more while preserving audio quality....

Extract the audio from a recorded Zoom or Teams meeting to share as a standalone audio file. Convert a downloaded video lecture to MP3 before transcribing it with a speech-to-text tool. Pull the audio track from a video production file for use as a podcast episode source. Archive audio commentary from a video file after the video itself is no longer needed.

Frequently asked questions 3 answers

We extract the audio stream directly from the container when possible, minimizing quality loss. The output audio quality depends on the original video's audio bitrate.

Free accounts can upload MP4 files up to 100MB. Pro allows files up to 500MB.

Currently the tool is optimized for MP4. For other formats, try the Video Compressor which supports broader input formats.
