Free Audio Extractor from Video Online — Extract MP3 from MP4
Extract the audio track from any video file as a high-quality MP3, AAC or OGG. Browser-based, no software needed. Upload MP4, MOV, AVI, MKV or WebM and download audio instantly.
Lossless audio extraction
When the video contains an AAC or MP3 audio track (most MP4 files), the audio is extracted without re-encoding — the exact audio stream is copied, preserving 100% of the original audio quality. When the video uses a different audio codec (AC3, DTS, PCM), a conversion step is applied at high quality. The result is always the best possible audio quality from the source video.
Use cases for audio extraction
Podcast creation: record your podcast on video (for YouTube) and extract the audio for audio-only distribution. Music extraction: save the audio from a music video, concert recording or YouTube video download. Transcription: extract audio from a video lecture or interview before running it through transcription software. Voice-over extraction: separate a voice-over track from a video for editing. Audio archiving: extract and archive audio from old VHS conversions or digitized home videos.
FAQ
What audio format does the extraction produce?
MP3 at 192 kbps by default. You can also choose AAC (better quality at smaller size) or OGG Vorbis (open format) in the options.
Is the extracted audio the same quality as in the video?
Yes, when no re-encoding is needed (MP4 with AAC audio). For videos using other codecs, conversion occurs at high quality with minimal loss.
What video formats are supported?
MP4, MOV, AVI, MKV, WebM and FLV. The tool extracts audio from any video file with an audio track.
Can I extract audio from a YouTube video?
You can extract audio from a video file you have already downloaded. Direct extraction from YouTube URLs is not supported due to platform terms of service.
What is the maximum video file size?
Videos up to 500 MB are supported for audio extraction.
Can I extract only a portion of the audio?
Not directly in this tool. Trim the video first with our Video Trimmer to the desired segment, then extract the audio from the trimmed clip.
