AAC format guide

What to know before converting AAC

AAC is a lossy audio codec; a .aac file usually carries raw ADTS AAC, while MP4 and M4A can also contain AAC streams.

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.

Use AAC for efficient playback and streaming, or convert to MP3 when an older player rejects AAC.

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.

Transcoding AAC to another lossy codec introduces another generation of loss.

If a AAC 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 AAC is generally supported. Try a different published target only when it fits your goal; changing the extension by hand does not convert the file.
