Does converting AAC to WAV improve audio quality?
No. Converting to WAV preserves the current quality without adding further compression, but it cannot restore audio data that was discarded when the AAC file was created.
Why convert AAC to WAV?
WAV is the standard format for audio editing and professional production. Converting to WAV before editing prevents additional quality loss from re-encoding.
Are my files uploaded to a server?
No. All conversion happens in your browser using the Web Audio API. Your files never leave your device.
Can I convert M4A files?
Yes. M4A is an AAC audio file in an MP4 container. This tool converts M4A files the same as AAC.
Why are WAV files so large?
WAV stores raw uncompressed audio data. A minute of stereo audio at CD quality is about 10MB as WAV compared to roughly 1MB as AAC.
Can I convert multiple files at once?
This tool converts one file at a time. Process each file individually for batch needs.
