converted on your device — your video is never uploaded
ℹ️ This extracts audio from a video file you already have (a recording, a lecture, your own clip). It is not a YouTube/TikTok downloader.
Sometimes the picture does not matter: a lecture you want to listen to on a walk, an interview you need to transcribe, a voice you recorded as video by mistake, a song from your own performance. This tool takes the audio track out of a video and saves it as an MP3 that plays on any device.
It works on files you already have: MP4 and MOV from a phone, WebM, MKV and the other common formats. The extraction runs in your browser with the FFmpeg engine, so the video is not uploaded, and because there is no upload there is no file-size cap beyond what your device's memory can hold.
To be clear about what it is not: this is not a YouTube, TikTok or Instagram downloader. It does not fetch anything from the internet; it converts a file that is on your device. If what you actually want is the words rather than the sound, the Video to Text tool transcribes the speech directly.

Frequently asked questions
- Can I download YouTube videos with this?
- No. This tool only works on video files you already have on your device (a recording, a lecture, your own clip). It is not a YouTube or TikTok downloader.
- Is my video uploaded?
- No — the audio is extracted on your device using WebAssembly.
- Does the MP3 sound as good as the video?
- For speech, yes. For music it is very close: MP3 is a compressed format, and the file is saved at a bitrate where the difference is hard to hear.
- How long can the video be?
- There is no set limit. Long videos take longer and need more memory, so a two-hour recording is better handled on a computer than on a phone.
Guides
- How to make a video file smaller without ruining it Four things decide how big a video is: length, resolution, bitrate and codec. Which one to change for email, WhatsApp, a website or a USB stick, the arithmetic behind "fit under 25 MB", and why trimming first is free.
- How transcription in your browser works, and why nothing is uploaded A plain explanation of how a web page can turn speech into text without sending your recording anywhere: the Whisper model, the one-time download, what the Fast, Accurate and Best settings change, and what to expect on a phone.
