About this tool
Converting AAC to WAV
AAC is the modern lossy successor to MP3 — better quality at the same size, and the standard audio codec of streaming platforms and mobile devices. WAV stores audio uncompressed — every sample bit-exact, editing-grade quality, at roughly ten times the size of MP3. Decoding to WAV gives editing software uncompressed samples — the correct first step before any cutting or effects work.
What to check after converting
Listen to a section you know well — the beginning, the loudest part — and compare it against the original file. The WAV output is an exact capture of the decoded source. Your original file stays untouched on your device either way.
Frequently asked questions
Will converting AAC to WAV reduce the quality?
No further loss — WAV stores the decoded audio exactly, though what earlier lossy encoding discarded stays discarded.
Is my audio file uploaded anywhere?
Small files convert entirely in your browser; larger ones finish on our servers and auto-delete within an hour. Either way, nothing is kept, shared, or used for anything else.
Why would I pick WAV over AAC?
Decoding to WAV gives editing software uncompressed samples — the correct first step before any cutting or effects work.
