Before converting

Quality and limitations

Converting audio does not improve the quality of the original recording. The finished AAC file depends on the clarity and condition of the source file.

AAC output is designed for compact, modern audio playback.

Your selected file is processed on your device. For long or large files, keep the page open and avoid running too many other applications until conversion finishes.

Damaged, protected, or unusually created files may not open successfully. If conversion fails, try the original file or a more widely supported source such as MP3 or WAV.
