How do I convert a CAF file to AMR?

Upload your CAF file using the converter, select AMR as the output format (choose AMR-NB or AMR-WB if available), optionally adjust the bitrate, then click 'Convert'. Once processed, download the converted AMR file. No extra software is needed—conversion happens in your browser.

Why should I convert CAF to AMR?

CAF files are common on Apple devices but are less compatible with non-Apple systems. AMR is a standard speech codec used across mobile phones, VoIP services, and embedded devices. It compresses voice data to a fraction of the original size, which is ideal for sending voice memos, creating ringtones, or storing long recordings on devices with limited storage.

What happens to audio quality when converting CAF to AMR?

AMR encoding is lossy, meaning it discards some audio data to achieve small file sizes. The audio is resampled to 8 kHz for AMR-NB or 16 kHz for AMR-WB, and the bitrate ranges from 4.75 to 12.2 kbps. Speech quality remains intelligible, especially at higher bitrates, but music and high-fidelity audio will lose detail. Metadata like album art and track names are not preserved in the AMR container.

Is CAF-TO-AMR free to use?
