Video to MP3
Pull the soundtrack out of a video and save it as MP3.

How do I get the audio out of a video as an MP3?
Drop the video onto filetity's video to MP3 converter and the soundtrack comes out as an MP3 you can play on the page before saving. Everything happens in the browser tab, so the video is never uploaded, which matters when it is a lecture, a meeting recording or anything filmed at home. The picture is discarded rather than decoded, so the conversion takes about as long for a 4K file as for a 720p one of the same length, and the resulting file is small because nearly all of a video's size is picture: the soundtrack of a 500 MB video is usually 3 to 10 MB. M4A and WAV are offered as well, and WAV is the one to pick when you want the audio with nothing thrown away at all.

When you would use this
Situations, not settings.
- A lecture or a talk you want to listen to while walking
- The soundtrack of a 500 MB recording is usually under 10 MB, which fits on a phone and plays in the background where a video will not.
- An interview you recorded on camera and need to transcribe
- Transcription tools want audio, and the picture is dead weight to them. The conversion never uploads the recording, which matters when the interview was confidential.
- Music or a sound effect from something you filmed
- Pull the audio out once and edit from that, rather than dragging a large video file into an audio editor every time.
How it works / no cloud
A conversion engine, not an upload form.
The video's audio track is read out of its container and re-encoded to MP3 by an encoder that runs in your browser, because Chrome can decode MP3 but cannot write it. The picture is discarded rather than decoded, so the work is proportional to the soundtrack and not to the resolution: a 4K file is no slower than a 720p one of the same length.

Straight answers
No accordion. Nothing hidden.
- Is it free?
- Yes, with no watermark and no page limit.
- Does it need an account?
- No. There is no account system.
- Is my file processed on my device?
- Yes. The file is read by your browser and never uploaded. There is no server to send it to.
- What formats are supported?
- MP4, MOV, WebM and MKV in. MP3 out, or M4A and WAV if you prefer.
- What are the limits?
- One file at a time, and the whole file is read into memory, so length is the practical limit rather than resolution. A video with no audio track is refused with a clear message rather than producing an empty file.
- Does it work on mobile?
- Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.
- Does it work offline?
- Yes, once the page has loaded. The tool keeps working with no network connection.
- Does the video's resolution affect how long this takes?
- Barely. The picture is skipped rather than decoded, so a 4K file and a 720p file of the same length take about the same time. What does matter is the length of the recording, because every second of sound has to be decoded and re-encoded.
- Will the MP3 sound worse than the video did?
- A little, because the audio inside a video is already compressed and this compresses it again. The tool never asks for a higher bitrate than the source spent, so it will not inflate the file pretending to add quality back. If you want no loss at all, save as WAV, which stores the decoded audio exactly and is much larger.
- Can I get just part of the video's audio?
- Not on this page, which converts the whole soundtrack. Save the MP3 here and then open the trimmer to cut it to the section you want, which keeps this page to one job and means the trim happens on a much smaller file.
- Is it legal to do this?
- That depends entirely on the video, and nothing about doing it locally changes the answer. Your own recordings, lectures you were given, and anything licensed for reuse are fine. Extracting a commercial soundtrack you do not have rights to is not, wherever the conversion happens.
- Why is the file smaller than I expected?
- Because almost all of a video file is picture. The soundtrack of a 500 MB video is usually somewhere between 3 and 10 MB, so seeing a small file is the tool working rather than something having gone missing. The player on the page lets you check the length and listen before you save it.
