Convert AMR to WAV
Ethical Tube's free AMR to WAV converter turns AMR recordings into WAV, uncompressed audio for recording and editing. It runs entirely in your browser, so your recordings are never uploaded, and it's free with no sign-up or watermark. The first conversion downloads the FFmpeg engine (10 MB) once, and it's cached after that.
Files are converted on your device and never uploaded.

The formats
AMR and WAV at a glance
What is an AMR file?
AMR is a compressed audio format designed for speech. Phone calls, voice recorders, and voice messages on older phones use it. Files are tiny, music sounds muffled, and most computers can't play AMR without extra software. It opens in VLC, some Android phones, and specialized audio software. Windows, Mac, and iPhone generally can't play it.
What is a WAV file?
WAV is an uncompressed audio format from Microsoft and IBM. It keeps the full quality of a recording, which is why studios, podcasters, and editing apps use it, but one minute of CD-quality stereo takes about 10 MB. It opens in every computer and phone, every audio editor (Audacity, GarageBand, Logic Pro, Pro Tools), and all browsers.
Good to know
What changes when you convert AMR to WAV
- WAV is lossless, so no more quality is lost, but it can't restore what AMR compression removed, and the file gets bigger.
- The audio is saved as uncompressed 16-bit WAV.
- AMR files are converted with FFmpeg running in your browser.
- The first conversion downloads FFmpeg compiled to WebAssembly (10 MB). It's cached, so later visits start quickly.
- Copy-protected (DRM) files can't be converted.
- Very long videos can run out of memory, especially on phones.
FAQ
Questions, answered
Is this AMR to WAV converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with FFmpeg compiled to WebAssembly, so your files never leave your device. Once the page and the engine have loaded, it even works offline.
Does converting AMR to WAV lose quality?
No. WAV is lossless, so nothing is lost in the conversion. It can't add back quality that the AMR compression removed, though.
Can I convert several AMR files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each WAV file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
Yes, in any current browser on a computer or phone. FFmpeg runs on your processor without hardware acceleration, so long videos are much faster on a computer.
What can open a WAV file?
Every computer and phone, every audio editor (Audacity, GarageBand, Logic Pro, Pro Tools), and all browsers.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and a computer can usually handle recordings several hours long.
