Video to MP3

Pull clean MP3 audio from almost any video without uploading it anywhere. Choose the exact audio track, trim precisely, tune quality, normalize loudness, add fades and tags, and optionally use a video frame as cover art.

Choose the right audioMulti-track videos are inspected first, so you can choose the language or commentary track you actually want.

Audio-first controlsTrim, normalize, fade and tune MP3 quality without navigating a full video editor.

Real MP3 tagsAdd title, artist, album, year and track metadata, plus optional embedded cover art from the video.

No upload queueNormal processing stays on your device. Nothing is sent to OneFreePlace just to extract audio.

Browser media processing is memory intensive. Very large files can exceed device memory or WebAssembly limits. OneFreePlace serves the pinned FFmpeg/WebAssembly engine. Conversion still uses your device memory.
