Frequently asked
Is my video uploaded?+
No. Audio extraction runs entirely inside your browser via ffmpeg.wasm. Your file never touches a server.
Which format should I choose?+
MP3 at 192 kbps is the universal default — works everywhere, small files, transparent quality for music. WAV is lossless but huge. AAC is slightly more efficient than MP3 at the same bitrate. OGG (Vorbis) is open-source.
Can I extract audio from a YouTube video?+
Not directly. You first need a video file. This tool works on any video already on your device — it doesn't fetch from streaming services. Use the YouTube thumbnail tool for image grabbing only.
How long can the file be?+
Up to 500 MB. A 90-minute movie typically fits. Very large files may pause if your browser runs low on memory.
Why is the first run slow?+
The first conversion downloads ~30 MB of WebAssembly (ffmpeg core) from a CDN. After that the runtime is cached and starts instantly.
