About This Tool
This free MP4 to WAV converter extracts uncompressed audio from your video files in PCM WAV format. WAV is the standard uncompressed audio format used in professional audio editing, music production, mastering, and CD authoring. Unlike MP3 extraction, WAV output preserves the full audio quality without any additional lossy compression — ideal for post-production workflows where you need to apply effects, mix, or further process the audio. All processing happens directly in your browser using WebAssembly technology — your videos are never uploaded to any server.
Frequently Asked Questions
Why extract WAV instead of MP3 from video?
WAV is uncompressed, making it ideal for professional audio editing, mixing, and mastering. MP3 applies lossy compression which can introduce artifacts when you later edit or re-encode the audio.
What video formats are supported?
This converter supports MP4, MOV, WebM, AVI, and MKV video formats. Most common video files will work.
How large will the WAV file be?
WAV files are significantly larger than compressed formats. A 5-minute video will produce a WAV file around 50 MB at CD quality (16-bit, 44.1 kHz stereo). The exact size depends on the audio sample rate and channels.
Can I trim the audio before extracting?
Yes! Enable the 'Trim audio' option to set start and end times. You can use the video player to find the exact timestamps you need.
Are my videos secure during conversion?
Yes! All conversion happens locally in your browser using FFmpeg WebAssembly. Your videos are never uploaded to any server, ensuring complete privacy.
