What does the AAC to AMR audio converter do?
+
It re-encodes a AAC audio file as AMR. Sample rate and channel count are preserved; the difference is the codec and container.
Will the sample rate and channel layout be preserved?
+
By default yes — stereo stays stereo, the original sample rate (44.1 kHz, 48 kHz, etc.) is carried through to the AMR output.
Is the AAC to AMR conversion reversible?
+
You can convert the AMR back to AAC on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
What output quality should I expect from AAC to AMR?
+
Default settings target broadcast / web quality — visually identical to the source for most viewers. For archival use, pick the highest quality option in the converter settings.
Is there a file-size limit when converting AAC to AMR?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several AAC files to AMR at once?
+
Yes. Drop or pick multiple AAC files in one upload — the converter processes them in parallel and returns a ZIP of the AMR results. There is no need to repeat the upload step per file.
What happens to my AAC files after the conversion?
+
Uploaded files and AMR outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.
What apps can play a AMR file?
+
AMR plays in most music players, browsers, and media libraries. iTunes / Apple Music, VLC, Foobar2000, and phone media apps handle it natively.
Do I need to install software to convert AAC to AMR?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
Do I need an account to convert AAC to AMR?
+
No. AAC to AMR conversion is free and works without an account. Signing in unlocks higher file-size caps, batch history, and API access.
Is there an API for AAC to AMR conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. AAC to AMR is one of the supported pairs.
What if my AAC fails to convert to AMR?
+
Failures are usually caused by corrupted source files or unsupported AAC variants. Re-export from the original app and try again; if it still fails, the contact page forwards the file to support so we can diagnose.
