About video to mp3
Extract audio track from any video file and download as MP3. Fast browser-based conversion.
Video to MP3 runs on FFmpeg compiled to WebAssembly, so your video is processed on your own device instead of being uploaded to a server. The engine downloads once the first time you use a video tool and is cached after that. There is no queue, no watermark and no account.

Frequently asked
Is my video uploaded to a server?
No. Extract Audio from Video runs entirely in your browser using FFmpeg compiled to WebAssembly. Your video never leaves your device and we don’t store anything.
Which formats are supported?
MP4, MOV, WebM, AVI, MKV and most formats your browser can decode. Output is MP4, GIF, MP3 or PNG depending on the tool.
Is there a file size limit?
We don’t impose one. Processing time scales with length and resolution, and files over a few hundred MB can exceed a phone browser’s memory — compress or trim first if that happens.
Is Video to MP3 free? Do I need an account?
Yes, it is completely free and there is no account, sign-up or watermark. It is one of 78 free browser tools from ModelsGroup.
Does it work on my phone?
Yes, in recent versions of Safari and Chrome. Video encoding runs on the phone’s CPU, so long clips take longer than on a laptop.
