AMR to WAV: what to expect
AMR does not open in most apps and browsers. WAV is uncompressed, so audio editors and transcription tools accept it without fuss. AMR is at home in voice recordings on older phones; WAV is the usual choice for recording, editing and mastering. WAV cannot bring back detail that AMR compression already removed; it simply stores the result without further loss, in a larger file.
The defaults suit most files. Under Options you can trim the start and end.
This pair uses the compatibility engine, ffmpeg built for the browser, because AMR is not handled by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB.
AMR vs WAV
WAV

WAV stores audio as raw, uncompressed samples. Nothing is lost, which makes it the standard working format in audio editing, and files run to about 10 MB per minute at CD quality.

Questions
Are my voice recordings uploaded anywhere?
No. The AMR to WAV conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
Does converting AMR to WAV reduce quality?
Nothing more is lost: WAV is uncompressed, written as 16-bit audio, the same as a CD. It cannot restore what AMR compression already discarded, and the file will be larger.
Can I convert several AMR files at once?
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
How do I convert AMR to WAV on Windows, Mac, iPhone or Android?
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the AMR file, press Convert and save the WAV. There is nothing to install.
Is there a file size limit?
Yes. AMR to WAV runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
