Last updated
Quick answer: To convert AMR to AIFF, add the AMR file to the iHateFiles AMR to AIFF converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. AMR is a format most software has stopped opening. AIFF is not.
Should you convert AMR to AIFF?
Do this when an editor, DAW or device needs AIFF. It will not make the AMR sound any better, and the file grows several times over.
AIFF will not restore what AMR removed
AIFF stores every sample exactly, including the damage AMR compression already did. Expect about 10 MB per minute instead of about 0.1 MB, for audio that sounds identical. Do it because an editor or device needs AIFF, not to improve the sound.
AMR was made for voices
AMR is a phone-call codec that keeps only the frequencies speech needs, roughly up to 4 kHz. Converting to AIFF makes the recording open everywhere, but it will still sound like a phone call, because the rest of the sound was never recorded.
Where the AIFF will play
AIFF plays on Macs, Logic, GarageBand and most DAWs.

What usually goes wrong
About the AMR. Converting AMR to a high bitrate does not improve it. The frequencies were never recorded.
About the AIFF. AIFF and WAV are the same audio at the same size; only the byte order and metadata differ. Converting between them changes nothing you can hear.
How to convert AMR to AIFF
- Add your AMR file. It is read from your disk and stays there.
- Check the settings. The output format is already set to AIFF.
- Press convert and the AIFF file is saved back to your device.
Questions
How do I convert AMR to AIFF?
Open this page, add your AMR file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this AMR to AIFF converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to AIFF lose quality?
AIFF is lossless, so this step throws nothing away. If the original was already a lossy format, the damage it did cannot be undone, but nothing further is lost.
Can I convert several AMR files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
