How to extract audio from a video without installing anything
There is no app to install and no account to create. You pick the video, we pull out the soundtrack and you download an MP3 or a WAV, with no queue and no usage cap. Use it to grab the music from a clip, the audio of a lecture or the sermon from a recorded service.
Whether it works depends on the video format and the browser. Phone and camera footage in MP4 or MOV with AAC audio opens in any current browser. Some MKV and AVI files, or less common audio codecs, may not. When that happens the tool tells you, and you can try another browser.
| Video format | What to expect |
|---|---|
| MP4 (phone, camera, YouTube) | Works |
| MOV (iPhone, camera) | Works |
| WebM | Works |
| MKV | Depends on browser and codec |
| AVI | Depends on browser and codec |
MP3 or WAV: which should I use?
MP3 is the default here: compressed at a constant 192 kbps, it takes about 1.4 MB per minute and plays on any phone, player or messaging app. It is the right pick for listening, sending in a chat or publishing a podcast.
WAV stores sound uncompressed, at 16 bits. It takes about 11 MB per minute in stereo at 48 kHz, but nothing is lost between exports, which is why editors prefer it in Premiere Pro, DaVinci Resolve or an audio editor. If you only want MP3 of the lines that matter, FilmScribe transcribes the video and downloads MP3 of the passages you pick in the transcript.
| Feature | MP3 (default) | WAV |
|---|---|---|
| Compression | Lossy, constant 192 kbps | None, 16-bit |
| Size per minute (stereo) | About 1.4 MB | About 11 MB at 48 kHz |
| Plays on | Any device | Video and audio editors |
| Best for | Listening, sharing, publishing | Editing and mixing |
Does it work with long videos, like a full service?
Yes. The audio is read piece by piece, so a short phone clip takes seconds and a two-hour church service takes a few minutes, with the progress shown as a percentage on the button. If you change your mind halfway, just cancel.
In MP3 mode you see the conversion progress as a percentage, and the final file stays light. WAV grows fast: about 11 MB per minute in stereo at 48 kHz, or half that in mono. If the WAV gets too heavy, switch to MP3 or mono.
- 1 hour as MP3 (192 kbps): about 82 MB.
- 1 hour as WAV, stereo, 48 kHz: about 660 MB.
- 1 hour as WAV, mono, 48 kHz: about 330 MB.
Does converting video to MP3 reduce quality?
A little, because MP3 is compressed. At 192 kbps, voice and music sound good for listening and publishing. If the audio is headed for editing or mixing, choose WAV: it is written uncompressed, so nothing is lost in the extraction. Neither format adds quality that was never there: if the video's sound was recorded low, the file will sound the same.
Keep 48 kHz if the audio goes back into a video project, and use 44.1 kHz for a music project. Mono makes sense when there is a single voice, like a sermon picked up by the pulpit mic. Stereo is worth keeping for music, worship sets and interviews recorded with two mics panned apart.

Frequently asked questions
How do I convert a video to MP3 for free?
Choose the video on this page, keep the format on MP3 and click extract audio. You get a 192 kbps MP3, ready to play on your phone, send in a chat or publish. It is free, with no sign-up, no watermark and no usage cap.
What quality is the MP3?
The MP3 is a constant 192 kbps (CBR), in stereo or mono, at 48 or 44.1 kHz. That is a solid bitrate for voice and music, at about 1.4 MB per minute. If the audio is going into an edit, choose WAV, which is 16-bit and uncompressed.
MP3 or WAV: which should I use?
Use MP3 for listening and sharing, WAV for editing. MP3 is lossy and much smaller, about 1.4 MB per minute. WAV stores sound uncompressed, so nothing is lost between exports, but it takes about 11 MB per minute in stereo at 48 kHz.
Does it work with long videos?
Yes. One or two hour recordings work and take a few minutes, with the progress shown as a percentage. WAV files come out large; switching to MP3 or mono shrinks them a lot.
Why did my video fail?
Your browser could not read that container or audio codec. It happens with some MKV and AVI files. Try opening the page in another browser, or convert the video to MP4 first. Phone and camera MP4 or MOV files almost always work.
Can I download just part of the audio as MP3?
Not with this tool: it converts the audio of the whole video. To get MP3 of a single line, upload the video or paste a YouTube link in FilmScribe. We transcribe it word by word, you mark the passages in the transcript and download each one as MP3.
Is there a watermark or a usage limit?
No watermark, no sign-up and no usage cap. Pick a video, extract it and download the MP3 or WAV as many times as you like.
Transcribe your video's audio automatically. Then grab only the part you need.
Upload a video or paste a YouTube link. We transcribe it word by word and you download MP3 of the full audio or of the lines you choose.
