Frequently Asked Questions
Video to MP3 conversion explained.
Is my video uploaded to a server?
No. FFmpeg.wasm runs entirely in your browser. Your video never leaves your device, making this completely private.
Which bitrate should I choose?
128 kbps is sufficient for speech and podcasts. 192 kbps is transparent for most music. 256 or 320 kbps is for audiophiles or archiving. Higher bitrate doesn't improve quality beyond the source video's audio — it just preserves more of what's there.
Why does conversion take a while?
FFmpeg.wasm is powerful but runs in a browser sandbox. On first use, the FFmpeg core (~10 MB) loads from CDN. Audio extraction itself is fast — typically faster than real-time for most files.
What if the video has no audio?
The tool detects missing audio tracks and shows an error. Screen recordings, some animations, and muted videos may have no audio stream.
Can I convert YouTube videos?
This tool converts files you upload from your device. It does not support URLs or direct YouTube downloads. Download the video first using an authorized tool, then convert here.
