This tool supports all common video formats including MP4, MOV, AVI, MKV, WebM, FLV, WMV, and more. FFmpeg automatically detects the video format and extracts the uncompressed audio stream as WAV.

WAV is uncompressed and lossless, preserving the original audio quality without any compression artifacts. It's ideal for professional audio editing, production work, archival, or when you need maximum quality. WAV files are much larger than MP3/AAC but contain all audio data.

Use WAV when you need to edit the audio in a DAW (digital audio workstation), create high-quality samples, preserve archival material, produce professional music or podcasts, or perform audio analysis. For casual listening or file size constraints, use AAC or MP3 instead.

Choose 'Original' to preserve the video's native sample rate. Use 48kHz for video production (industry standard), 44.1kHz for CD quality or music production, or 96kHz for professional audio work. Higher sample rates create larger files but capture more frequency detail.

WAV files are uncompressed, so they're much larger than MP3/AAC. A 5-minute song at 44.1kHz stereo is approximately 50MB as WAV, compared to 5-10MB as MP3/AAC. File size increases with sample rate and audio duration.

No—extraction preserves the existing audio quality but cannot improve it. If the video has compressed audio (MP3, AAC), extracting to WAV creates a lossless container for already-compressed data. For true lossless audio, start with lossless source material.

Yes, but WAV files are large and may consume significant storage. Modern smartphones support WAV playback, but for mobile listening, converting to AAC or MP3 is more practical. Use WAV primarily for editing or archival purposes.

Extraction speed depends on video length, selected sample rate, and your device. A 5-minute video at original sample rate typically processes in 10-30 seconds on modern computers. Higher sample rates or longer videos take proportionally longer.

Currently, this tool processes one video at a time for optimal browser performance. For multiple files, process them sequentially. Each extraction uses your selected sample rate settings.

No. All processing happens entirely in your browser using FFmpeg WebAssembly. Your video files never leave your device, ensuring complete privacy. No server uploads, no cloud processing.
