Convert AMR to MP3

AMR is a speech codec used by older phones for voice memos and call recordings. Few computers play it, so converting to MP3 is the easiest way to keep and share those recordings.

Frequently asked questions

Why is 96 kbps preselected?

AMR recordings are narrowband speech. A higher MP3 bitrate only makes the file bigger without sounding any better.

Can I make the recording clearer?

Try Reduce Background Noise after converting, and Change Video Volume to raise a quiet recording.

Which format should I convert to?

MP3 for playback anywhere, M4A for Apple devices, WAV or FLAC for editing and archiving, Opus for the smallest voice files.

Can I convert WhatsApp voice notes?

Yes. WhatsApp voice notes are Opus audio in an OGG container; drop them in and convert to MP3.

Does converting MP3 to WAV improve quality?

No. The WAV holds the same sound as the MP3, just uncompressed. It is useful for editors that need WAV, not for better quality.

Should I choose mono?

For speech, mono halves the file size with no loss in clarity. Keep stereo for music.

Is my audio uploaded?

No. FFmpeg converts it inside your browser.

Can I convert on my phone?

Yes. Audio conversion is light and quick in mobile browsers.
