Extract the audio track from an MP4 as an uncompressed WAV file, lossless, full length, at the original volume. It's free, needs no account, adds no watermark, and your video is never uploaded.

Why choose WAV over MP3

Reach for WAV when the audio is going somewhere else to be worked on, an edit, a mix, a master, a transcript. WAV is uncompressed, so every sample from the original MP4 track comes through with no compression artifacts. That matters because editing and re-exporting an MP3 stacks lossy compression on top of lossy compression, and you can hear it. A WAV survives repeated cuts, fades, and effects without degrading. The trade-off is size: expect roughly 10 MB per minute for standard stereo, so an hour of audio lands near 600 MB. If you just need a portable listening copy, MP3 makes more sense.

Which editors and workflows this fits

WAV is the universal exchange format for audio work, which is why this extraction targets it. Import the file into Audacity, Adobe Audition, Logic, Reaper, or any other DAW and it opens natively, no transcoding, no quality loss at the door. It's also the cleanest source for transcription tools and speech models, which prefer uncompressed input. The extraction is deliberately plain: full-length audio at the original volume, no bitrate setting because WAV isn't compressed. There's nothing to configure and nothing to second-guess. You get the raw track exactly as it sat inside the video, ready to shape however your project needs.

What to expect from the output

The WAV mirrors the MP4's audio exactly: same duration, same channels, same loudness as the source. This tool extracts only, it does not trim, fade, normalize, or merge, so if the original track is quiet or has silence at the head, that carries over untouched. Do that shaping in your editor afterward, where you have proper meters and undo. Plan for the file size before you start: a two-minute clip is around 20 MB, a full podcast episode can run into the hundreds of megabytes. Once you've finished editing, you can always bounce down to a compressed format for delivery.

Tips

Keep the WAV as your working master and export MP3 or AAC copies only for final delivery.
Budget disk space ahead of time, about 10 MB per minute of stereo, so longer videos add up fast.
Since extraction is full-length, cut the sections you don't need inside your DAW after importing.
For transcription, feed the WAV directly to your speech tool; uncompressed audio gives cleaner results than a re-encoded MP3.

Questions

Is my MP4 uploaded to a server?: No. Your file is processed privately and never uploaded, there's no account to create, and nothing is watermarked. The video stays with you the whole time.
Why is the WAV file so much bigger than my MP4?: WAV is uncompressed, so it stores the full audio with no space-saving compression, roughly 10 MB per minute for standard stereo. That size is the reason it stays artifact-free through editing.
Can I set the bitrate or quality?: There's no bitrate option because WAV is uncompressed, there's no lossy setting to choose. You get the audio exactly as it exists in the source MP4.
Does it trim or adjust the volume?: No. Extraction is full-length at the original volume. The tool doesn't trim, fade, normalize, or merge, so any editing happens later in your own software.
