Sometimes the sound is the only part of a video you need. You may want to keep an interview as an audio file, reuse narration in an editor, save a voice recording, or listen to a clip without the picture. This free tool lets you extract audio from a video by uploading an MP4, MOV, or WebM file from your device.
The extractor creates an MP3, M4A, or WAV file from the first audio track in the uploaded video. It is a focused video-to-audio converter: there is no account to create, no software to install, and no unrelated editing timeline to configure.
How to Extract Audio from a Video Online
- Upload the video file. Drag one MP4, MOV, or WebM into the upload area, or select it from your device. The source can be up to 200MB and 30 minutes long.
- Choose the audio output. Keep MP3 selected for a widely compatible result, or choose M4A or WAV for a different workflow.
- Start the extraction. Select Extract Audio and wait while the server reads the video's first audio track and creates the new file.
- Check and download the result. Preview the extracted audio in the result card, then save it to your device before it expires.
MP4, MOV, and WebM files containing only audio, without a video track, are also supported. The file must still meet the size and duration limits and contain a readable, intact audio track. There is no audio to extract from a file with no audio track.
Convert Video to MP3, M4A, or WAV
The best output depends on what you plan to do next. Choosing a larger format does not improve a poor source, so use the format that matches your playback or editing requirements.
Convert Video to MP3 for Easy Playback
MP3 is the practical default for phones, computers, media players, messaging, and most publishing workflows. If the first audio track is already compatible MP3 and stays within the output limit, the tool prioritizes copying it without re-encoding. When conversion is needed, the track is encoded as MP3; audio with more than two channels is downmixed to stereo.
If you specifically need to convert an MP4 video to MP3, upload the MP4 and leave MP3 selected before starting the task. The same process works with supported MOV and WebM files.
Choose M4A for AAC or ALAC Workflows
If the first audio track uses compatible AAC or ALAC and stays within the output limit, it can be copied directly into M4A without re-encoding. When conversion is needed, the track is encoded as AAC, keeping the original channel count when the encoder supports it.
Extract WAV Audio for Editing
When the first track already uses a WAV-compatible PCM codec and stays within the output limit, the tool copies it without re-encoding. Other sources are converted to uncompressed 16-bit PCM. The source sample rate and channel count are retained when the result fits. If the estimated size is too large, the sample rate is first capped at 48 kHz; the audio is downmixed to stereo only if the estimate still exceeds the limit. WAV extraction accepts source files up to 10 minutes, and the generated WAV cannot exceed 150MB.
What Happens to the Video's Audio Track?
The tool reads the audio stream stored inside the video container and writes a new audio-only file. If the video contains multiple audio tracks, such as different languages, commentary, or surround mixes, the current version uses the first audio track; it does not provide a track selector. It first tries to copy a format-compatible track without re-encoding. When conversion is required, it retains the source properties where the selected format and output-size limit allow.
A compatible track that is copied directly avoids another generation of codec loss. When re-encoding is required, MP3 and AAC-based M4A use lossy encoding, which can change audio quality. WAV transcoding uses uncompressed 16-bit PCM, which may change the source bit depth. The sample rate or channel count may also be adjusted to meet the output-size limit. No format can recover detail already removed by the video's original audio encoding, repair clipping, remove noise, or make a low-quality recording clearer.
This is audio-track extraction, not stem separation. It does not isolate vocals from music, remove background sounds, or transcribe speech. The result contains the audio already present in the first audio track.
When Is a Video-to-Audio Converter Useful?
Save Speech Without the Picture
Turn a recorded interview, lesson, meeting excerpt, or narration take into an audio file that is easier to review or use in an audio workflow. Make sure everyone involved has agreed to the recording and reuse where required.
Prepare Audio for an Editor
Extract the soundtrack before placing it in an audio editor, digital audio workstation, or another production project. Choose WAV when the next application prefers uncompressed PCM, or MP3/M4A when a smaller working file is more important.
Listen to Material as Audio
For a video you own, an audio-only copy can be more convenient when the visuals are not needed. The tool does not download media from a video URL; upload the actual file from your device.
Supported Files and Limits
| Item | Current support |
|---|---|
| Input files | MP4, MOV, and WebM |
| Files per task | One |
| General upload limit | 200MB and 30 minutes |
| Audio outputs | MP3, M4A, and WAV |
| Output file size | Up to 150MB for all output formats |
| Audio preservation | First audio track only; direct copying preferred when compatible and within the output limit |
| WAV-specific limit | Source file up to 10 minutes |
| Videos with multiple audio tracks | First audio track only |
A matching extension alone does not guarantee that a file can be processed. Corrupted videos, encrypted or DRM-protected media, files without an audio stream, and some unsupported codecs may fail. Only upload media you own or are authorized to process.
Frequently Asked Questions
Is this video audio extractor free?
Yes. You can upload one supported video, extract its first audio track, and download the result without signing in or using Echora credits.
Can I convert an MP4 video to MP3 online?
Yes. Upload the MP4 file from your device, select MP3, and start the extraction. The tool copies the first audio track when compatible and within the output limit, or converts it to MP3 when needed. The MP4 must be no larger than 200MB, no longer than 30 minutes, and contain a readable audio track.
Can I extract audio from an online video link?
No. The tool processes MP4, MOV, and WebM files uploaded from your device. It does not fetch or download videos from YouTube, TikTok, social platforms, cloud links, or other third-party URLs.
Can I choose a different audio track?
Not currently. When a video contains multiple tracks, the extractor uses the first audio track. Select the required track in another editor before uploading if you need a different language or commentary track.
Why did audio extraction fail?
The video may have no audio stream, contain a damaged or unreadable track, use an unsupported codec, or be encrypted or protected. Confirm that the original plays with sound on your device and try a valid copy within the upload limits.
Does converting video to MP3 improve sound quality?
No. Direct copying can avoid additional codec loss when the source track is compatible, but it cannot add missing detail. When re-encoding is required, it also cannot improve a poor recording, so retain the original source when sound quality matters.
