How do I convert an AMR file to CAF using LetsConvert?

Go to the AMR to CAF converter, upload your AMR audio (e.g., a phone recording), choose CAF as output format, set sample rate (default 44.1 kHz) and channels, then click Convert. Once done, download the .caf file. No need to install software—everything runs in the browser.

Why should I convert AMR to CAF instead of keeping the original AMR?

AMR is a low-bitrate speech codec (typically 4.75–12.2 kbps) designed for mobile voice notes; CAF is Apple's audio container that supports high-quality PCM/AAC and is natively supported in macOS, iOS, GarageBand, and Final Cut Pro. Converting to CAF lets you edit, archive, or integrate the audio into Apple workflows without compatibility issues, though the file size will be larger because PCM is uncompressed.

What happens to the audio quality during AMR to CAF conversion—is it truly lossless?

AMR is a lossy codec, so the original recording already lost some fidelity. Our conversion decodes the AMR and stores the resulting PCM data in a CAF container. This step adds no further compression loss—it is sample-accurate to the decoded AMR. If you choose a higher sample rate (e.g., 48 kHz) the audio is up-sampled, but it cannot recover missing frequencies. Metadata like album art is not carried over since AMR typically lacks rich metadata.
