What happens to your file
AAC files are common for streaming, video soundtracks, mobile audio, but not every app or device opens them. WAV is ideal for audio editing, recording, sound effects, mastering. All-in-One Saver converts AAC to WAV with FFmpeg — real decoding and encoding, not a renamed file extension.
No quality is added. WAV is uncompressed or lossless, so the result is larger than your AAC, but the detail removed when the AAC was created can't be restored. Convert to WAV when an editor, DAW or device requires it.

WAV is lossless, so there is no bitrate to choose — you can only change the sample rate or switch to mono.
Can I convert several AAC files at once?
Yes. Drop up to 10 files at a time — each one is converted in parallel and you can download them individually or all at once.
Is there a file size limit?

Is this AAC to WAV converter free and safe?
Yes. There are no pop-ups, redirects or fake download buttons, and no software to install. Files are transferred over HTTPS, processed in isolated job folders and deleted automatically.
