Frequently Asked Questions
How does client-side video audio extraction work?
AG World Tools uses the native HTML5 Web Audio API. When you load a video, your browser demuxes the media container and decodes the audio track into a raw PCM AudioBuffer in RAM, which is then formatted into a RIFF WAV container for immediate download.
Is there any file size or duration limit?
Because decoding happens in browser memory, files under 500 MB and durations under 60 minutes work seamlessly across modern laptops and mobile phones.
Are my confidential video files uploaded anywhere?
Never. Zero bits leave your device. All processing is 100% offline-capable and client-side.
