How to convert AMR to FLAC
Add your AMR voice recordings
Drop AMR files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
FLAC is already chosen
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.
Download
Save the FLAC, or download everything as one ZIP if you converted several files.

Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
Free, without an account
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
AMR to FLAC: what to expect
AMR does not open in most apps and browsers. FLAC keeps full quality at about half the size of WAV. AMR is at home in voice recordings on older phones; FLAC is the usual choice for archiving music at full quality. FLAC 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 FLAC
FLAC
FLAC audio
FLAC compresses audio to roughly half the size of WAV without losing anything, like a ZIP for sound. It is the standard for lossless music collections. Apple's Music app is the notable holdout.

Questions
Are my voice recordings uploaded anywhere?
No. The AMR to FLAC 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 FLAC reduce quality?
No further quality is lost: FLAC stores the decoded audio exactly. 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 FLAC 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 FLAC. There is nothing to install.
Is there a file size limit?
Yes. AMR to FLAC 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.
