Convert MP4 to WAV
Save the sound of an MP4 as lossless WAV (16-bit PCM). Your file is never uploaded — it's processed right here in your browser.
How it works
01. Add your MP4 file
Drop or choose your MP4 file. Other video formats work too.
02. Pick the quality
Nothing to choose. It's saved as 16-bit PCM at the original sample rate.
03. Download the WAV
Hit Convert and download your WAV file when it's ready.
Why convert to WAV?
WAV is uncompressed, so it's the best input for audio editing, mixing and transcription tools — and re-saving never degrades it.
How the conversion works
The video is dropped and the audio is decoded into 16-bit PCM inside a WAV. With no compression it's fast, but the file is much larger than an MP3.
Frequently asked questions
How big is a WAV file?
About 11 MB per minute for 48 kHz stereo. Use MP3 to share, WAV to edit.
Is my video stored anywhere?
No. The file never leaves your device — it's processed inside this tab with WebCodecs. Close the tab and nothing is left behind.
Is there a file size limit?
Up to 2 GB per file. The result is held in your browser's memory, so on devices with little RAM smaller files are safer.
Which browsers are supported?
Recent Chrome, Edge, Safari and Firefox. Speed depends on your device — desktop Chrome and Edge are usually the fastest.
