About Extract Audio
Choose Original to copy the audio track exactly as it is stored in the video: it is instant and loses nothing, and the file type follows the track (for example M4A for AAC audio). Choose MP3 or another format when you need a specific type for a player or editor.
Processing happens in this tab with FFmpeg compiled to WebAssembly; your files are never uploaded. The first video or audio tool you use downloads the 10 MB engine once and keeps it cached for next time. Long or high-resolution videos take longer than on a desktop editor, especially on phones, where files are processed one at a time to stay within memory. Keep the tab open until the download appears.
Extract Audio: frequently asked questions
How do I extract the audio from a video?
Choose the video and an audio format: MP3, M4A, WAV, FLAC or Original. Then extract and download.
What does “Original” mean?
The audio track is copied exactly as it is stored in the video: instant and lossless. The file type follows the track, for example M4A for AAC audio.
Which format should I choose for music players?
MP3 plays almost everywhere. FLAC and WAV keep everything but are larger.
Can I extract audio from several videos?
Yes. Add a batch and each video gets its own audio file.
Are my videos uploaded?
No. FFmpeg runs inside your browser. The first video or audio tool you use downloads the roughly 10 MB engine from this site once; your files are never uploaded.
