Convert AAC to WAV
Decode an AAC file into uncompressed WAV so it imports cleanly into any DAW, sampler or editor. It all runs in your browser, so nothing is uploaded.
Why convert AAC to WAV?
Raw AAC files often refuse to import into DAWs, samplers and older editing software, and editing a lossy file directly can add further loss every time you export. WAV is the universal uncompressed format that every audio tool accepts. Convert when you need to edit, sample, chop or master audio that arrived as AAC, or when a tool only takes WAV.
Quality and file size
Converting to WAV decodes the AAC into uncompressed audio. It does not restore anything the AAC encode discarded, so the WAV sounds exactly like the AAC, just in a lossless container. The benefit is that further edits and bounces will not pile on extra lossy generations. Expect the file to be much larger, roughly ten megabytes per minute of stereo audio. Keep the WAV as your working file and export to a lossy format only at the end.
AAC to WAV: common questions
Does converting AAC to WAV improve the quality?
No. The WAV is a perfect copy of the decoded AAC audio, but it cannot bring back detail the lossy encode removed. What it does is stop further loss when you edit and export.
Is my file uploaded anywhere?
No. The conversion runs entirely in your browser with FFmpeg compiled to WebAssembly. Your file never leaves your device, and we never see it, store it, or train on it.
Why is the WAV so much bigger?
WAV stores audio uncompressed, while AAC is heavily compressed. A three minute stereo track that is a few megabytes as AAC can be around thirty megabytes as WAV. That is normal and expected.
When should I use WAV instead of AAC?
Use WAV while you are editing, sampling, mixing or mastering, since it avoids extra generation loss and imports everywhere. Use AAC or M4A for the final listening copy.
