Why Convert AMR to MP3?
AMR (Adaptive Multi-Rate) is a mobile voice recording format. MP3 is the universal audio format:
Universal Playback
MP3 plays on every device — phones, car stereos, Bluetooth speakers, computers. AMR support is limited to VLC and specialized apps.
Share Voice Recordings
Phone call recordings and voice memos saved as AMR can't be shared easily. MP3 works in email, messaging, and social media.

Does it work on mobile?
Yes. Works in any modern browser on all devices — no app installation required.
