AMR format guide

What to know before converting AMR

AMR is a speech codec used by older mobile phones and voice-recording systems, with narrowband and wideband variants.

What this converter actually supports

Published audio routes run through the deployed FFmpeg toolchain. The converter probes the source stream before conversion, and files without a decodable audio stream cannot produce an audio result.

Convert AMR voice notes to MP3 for sharing or WAV for transcription and editing.

The public upload limit is 1 GB. Convertr does not reduce dimensions, duration, resolution, or output quality merely to manage worker load.

Quality and format limits

WAV, AIFF, and FLAC are appropriate when decoded sample fidelity matters. MP3, AAC, Opus, WMA, and Vorbis are lossy; choose bitrate for the destination and do not expect a higher number to restore source detail.

AMR is optimized for speech, so music and high frequencies already discarded by the source cannot be restored.

Published AMR outputs

Choose one of these implemented routes; a listed extension is not a promise that every codec variant will decode.

If a AMR conversion fails

Check that the file opens in its original application, is not encrypted or DRM-protected, and really matches its extension. A damaged header, unsupported internal codec, missing linked asset, or mislabeled file can fail even when AMR is generally supported. Try a different published target only when it fits your goal; changing the extension by hand does not convert the file.
