How to use it
- Add your files. Drop AMR files on the page or use Choose files. Folders and ZIPs work too.
- Check that MP3 is selected. MP3 is already chosen on this page.
- Adjust options if you need to. Quality, size and other settings appear when the format has them.
- Convert and download. Press Convert; with several files, “Download all” gives you one ZIP.
What happens to your file
The audio is decoded and encoded as MP3 at the bit rate you choose.
MP3 is lossy, so pick a bit rate at least as high as the original’s to avoid audible loss.
About AMR and MP3
AMR: AMR is a speech codec used by phone call recorders and older Android voice recorders.
MP3: MP3 is the universal audio format: every phone, car stereo and app plays it.
Questions
Is my AMR file uploaded?
No. The conversion runs inside this browser tab, and the MP3 is created on your device. Nothing is sent to a server.
Is there a file size limit?
No fixed limit: files are processed by your device, so very large videos depend on its memory. Computers handle several GB; phones are best with smaller files.
Can I convert several AMR files at once?
Yes. Drop as many as you like, a folder or a ZIP; “Download all” saves every MP3 in one ZIP.
