Frequently Asked Questions

What is an AMR file?
AMR (Adaptive Multi-Rate) is an audio compression format optimized for speech coding. It was heavily used by early 2000s 3G mobile phones (like Nokia and Ericsson) for voice recordings and MMS messages.
Why convert AMR to MP3?
Because AMR is an outdated format natively supported mainly by older mobile hardware, modern smartphones, computers, and web browsers often cannot play these files. Converting them to MP3 makes your old voice memos universally playable everywhere.
Can this tool improve the audio quality?
No. AMR is a highly compressed, low-fidelity format designed for speech. Converting it to MP3 changes the file type so modern devices can read it, but it cannot restore audio frequencies that were permanently discarded during the original AMR recording.
Is my audio file strictly private?
Yes. Our converter uses WebAssembly to run the FFmpeg media engine directly inside your web browser. Your private voice recordings are never sent over the internet or saved to our servers.
