Extract the audio track from an MP4 video and save it as an MP3 file. Perfect for podcasts, music, and audio content.
MP4 to MP3 extracts the audio track from any video file and saves it as a high-quality MP3. Upload an MP4, MOV, WebM, or AVI video and get the audio extracted in seconds. Choose from three quality levels: 128kbps for compact files, 192kbps for balanced quality, and 320kbps for maximum audio fidelity. Processing happens entirely in your browser — your video is never uploaded to a server. Perfect for extracting podcast audio from video recordings, saving music from music videos, or isolating narration from video presentations.
Concrete advantages that save you time and effort.

Supports MP4, MOV, WebM, and AVI video formats
Direct audio stream extraction when possible for maximum quality
Fast processing — seconds for short videos, under a minute for long ones
Real-world scenarios where this tool saves hours of work.
Extract podcast audio from video recordings for audio platform distribution
Save audio tracks from music videos for offline listening
Isolate narration from recorded presentations for audio-only review
Extract meeting audio for transcription and note-taking tools

Watch your content flow through each processing stage.
Video files contain audio that often needs to exist separately. A podcast recorded as video needs an MP3 for audio platforms. A music video has a track you want to listen to offline. A recorded lecture has audio you want on your phone. A meeting recording has discussion you want to review without watching. MP4 to MP3 extracts that audio cleanly.
The extraction is not a re-encoding or conversion — it pulls the audio stream directly from the video file when possible, preserving the original quality. When the audio format requires conversion (such as AAC to MP3), the transcoding is done at the highest quality your selected bitrate allows.
Three quality levels serve different needs. 320kbps is audiophile-grade — indistinguishable from the original audio, ideal for music and high-quality podcast distribution. 192kbps is the standard for most uses — excellent quality with reasonable file sizes, perfect for lectures, meetings, and general listening. 128kbps produces compact files suitable for voice content, audiobooks, and situations where file size matters more than audio fidelity.
The entire process runs in your browser. Your video file is never uploaded to any server. This means privacy-sensitive content (meetings, confidential presentations, personal videos) stays on your device throughout the extraction. It also means the tool works offline once the page is loaded.
Multiple video formats are supported beyond MP4. MOV files from iPhones and Mac screen recordings. WebM files from browser-based recordings. AVI files from older video sources. The tool handles the most common video formats you will encounter.
For content creators, this is a core workflow tool. Record video content once, extract audio for podcast distribution, use the video for YouTube, and repurpose the audio for clips and social content. One recording, multiple output formats.
Processing speed depends on your device but is typically a few seconds for short videos and under a minute for hour-long recordings.
128kbps, 192kbps, and 320kbps. Higher bitrate means better quality.
Yes. Also supports MOV, WebM, and AVI.
Yes. Your file stays in your browser and is never uploaded to a server.
A few seconds for short videos, under a minute for hour-long recordings.
At 320kbps, the audio is indistinguishable from the original. Even 192kbps is excellent for most uses.
Currently the full audio track is extracted. Trim the video first using our video cutter if you need a specific segment.
