Frequently asked questions
Which video formats are supported?+
You can extract audio from MP4, WebM, AVI, MOV, MKV, and most other common video formats. The tool uses WebAssembly-based decoding that handles a wide range of codecs.
What audio formats can I export to?+
Extracted audio can be saved as MP3, WAV, OGG, AAC, or FLAC. Choose the format that best fits your needs — MP3 for small size, WAV or FLAC for lossless quality.
Does it extract the original audio track or re-encode?+
The tool decodes the video's audio stream and re-encodes it into your chosen format. If you select a format matching the original codec, quality loss is minimal.
Is there a file size limit for videos?+
There is no server-imposed limit since processing is local. Large video files depend on your device's memory. Most videos under a few gigabytes process without issues.
Is my video uploaded to a server?+
No. The entire extraction runs in your browser using WebAssembly. Your video file stays on your device and is never uploaded anywhere.
