Will my video files ever leave my device?No, all processing happens locally in your browser. Your video files never get uploaded to any server.
What video formats are supported?MP4, WEBM, OGV work best. MOV and other formats may work depending on your browser's codec support.
Can I extract audio from YouTube videos?You can extract audio from downloaded YouTube videos (MP4 files), but not directly from YouTube URLs due to browser security restrictions.
What's the difference between MP3 and WAV output?MP3 creates smaller, compressed files with excellent quality. WAV provides lossless, uncompressed audio but larger file sizes.
Video won't load or shows error? The video format may not be supported by your browser. Try converting the video to MP4 first, or use a different video file.
Extraction fails with "decode error"? The video's audio codec isn't supported. This commonly happens with older or proprietary formats. Try a different video or use desktop software for full format support.
No audio in the extracted file? The original video may not contain an audio track, or the audio is in an unsupported format.
Browser shows "not supported" message? Use Chrome, Firefox, or Safari for best compatibility. Internet Explorer and older browsers don't support the required APIs.
