Quick answer: To convert AMR to MP3, add the AMR file to the iHateFiles AMR to MP3 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. MP3 is not.
Should you convert AMR to MP3?
Yes. Very little current software opens AMR, so converting it is the way to keep listening to it. Pick a generous bitrate.
Both AMR and MP3 are lossy
AMR (AMR narrowband speech) has already discarded some of the sound, and MP3 (MPEG-1 Layer III) will discard a little more. The MP3 encoder works from the AMR, not the original recording, so pick a bitrate at or above the source. A lower one saves space and costs quality you cannot get back.
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 MP3 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 MP3 will play
MP3 plays on everything, including car stereos and hardware twenty years old.
AMR and MP3 side by side
| AMR | MP3 | |
|---|---|---|
| Inside the file | AMR narrowband speech | MPEG-1 Layer III |
| Compression | Lossy | Lossy |
| Carries sound | Yes | Yes |
| One minute of stereo | about 0.1 MB | 1 to 2.4 MB |
| Plays on | Needs converting first | everything, including car stereos and hardware twenty years old |
| Here | Read only | Read and write |
What usually goes wrong
About the AMR. Converting AMR to a high bitrate does not improve it. The frequencies were never recorded.
About the MP3. Converting an MP3 to another lossy format compounds the damage, because the second encoder is guessing at audio the first one already threw away.
How to convert AMR to MP3
- Add your AMR file. It is read from your disk and stays there.
- Check the settings. The output format is already set to MP3.
- Press convert and the MP3 file is saved back to your device.

Questions
How do I convert AMR to MP3?
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 MP3 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 MP3 lose quality?
MP3 is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
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.
