M4R to FLAC: what to expect
M4R is treated as a ringtone, so ordinary players may not list it as music. FLAC keeps full quality at about half the size of WAV. M4R is at home in custom iPhone ringtones and alert tones; FLAC is the usual choice for archiving music at full quality. FLAC cannot bring back detail that M4R 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.
The conversion uses your browser's own video and audio codecs (WebCodecs), with hardware acceleration where the device has it; the file is read from disk as it goes and can be up to 2 GB. Where the browser lacks a codec, the page falls back to the compatibility engine.
M4R 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 ringtones uploaded anywhere?
No. The M4R 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 M4R to FLAC reduce quality?
No further quality is lost: FLAC stores the decoded audio exactly. It cannot restore what M4R compression already discarded, and the file will be larger.
Can I convert several M4R 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 M4R 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 M4R file, press Convert and save the FLAC. There is nothing to install.
Is there a file size limit?
Yes. Files up to 2 GB are accepted. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
