Free MP4 to WAV that never uploads your file
Editors who want a WAV bounce from a phone video without opening Premiere first.
Why convert locally?
Most “online converters” ask you to upload a wedding video, lecture, or kids’ recital to a stranger’s server. savetool.org’s converters load FFmpeg in your browser instead. Teachers, journalists and anyone on a locked-down Chromebook can convert MOV to MP4, MP4 to MP3, WebM to MP4 or video to GIF without waiting on a queue or hitting a file-size paywall.
Use the MP4 to WAV for MP4 files when you need a quick format fix for WhatsApp, iPhone, Android, a smart TV, CapCut, Premiere or a classroom LMS.
Also download from TikTok, X and Facebook
If you don't have a file yet — only a link — use the TikTok, X or Facebook downloader first, then convert the file here if you need another format.

How does the MP4 to WAV work?
You drop a file and FFmpeg converts it inside your browser. The original never leaves your computer or phone.
Do you upload my video?
No. Conversion is 100% local. That's why it works on school and work networks that block upload sites.
Is it free?
Yes. No account, no watermark, no daily limit other than your device's speed and RAM.
What size files work?
Clips under about 250 MB are best. Huge 4K rips may run out of memory in the browser.
Does it work on iPhone?
Safari can convert shorter clips. Big files are more reliable on a laptop.
Is this the same as CloudConvert or Zamzar?
Same idea, different privacy model — those sites upload your file. We convert on-device.
