AAC to WAV
Convert AAC audio to WAV — right in your browser, nothing uploaded.
Drag & drop your AAC files here, or click to choose. Everything runs in your browser — nothing is uploaded.
AAC is a lossy format, the successor to MP3, with better quality per bitrate and native support on Apple devices and YouTube. People convert AAC to WAV because audio editors, DAWs and CD-burning tools work best with uncompressed WAV. This free AAC-to-WAV converter does the whole job inside your browser using a WebAssembly build of FFmpeg, so your audio is never uploaded to any server and there is no size limit or queue. Drop in one file or a whole batch, and each file converts automatically — then preview every result in place and download it. No signup, no watermark, and nothing to install.
Frequently Asked Questions
How do I convert AAC to WAV?
To convert AAC to WAV, drag your AAC files onto the drop area or click to choose them, and each converts to WAV automatically the moment it is added — there is no format to pick and no convert button. When a file finishes it appears as a row with its new name, size, an inline player to preview it and a Download button, and everything runs in your browser so nothing is uploaded.
Is this AAC to WAV converter free and private?
Yes on both counts: it is completely free with no signup, no watermark and nothing to install, and it is private because the whole conversion runs on a WebAssembly build of FFmpeg inside your own browser rather than on a server, so your files never leave your device. That makes it safe for private or unreleased recordings. The only download is the converter itself, a one-time roughly 32 MB file that is cached afterwards.
Will converting AAC to WAV lose quality?
The WAV file itself loses nothing, because WAV is lossless and stores exactly the audio it is given. But AAC is already a lossy format, so converting to WAV cannot restore detail the AAC encode already discarded — it simply stops any further loss, and the file becomes noticeably larger. It is best when you want a lossless master to edit or archive from here on.
Why convert AAC to WAV?
People convert AAC to WAV because audio editors, DAWs and CD-burning tools work best with uncompressed WAV. WAV is uncompressed PCM audio — perfect quality but large files, and playable on virtually everything. Converting re-packages your existing AAC audio into WAV so it drops straight into that device, app or workflow, without changing how the original was recorded.
Is there a file size or number limit?
There is no fixed size or count limit, because nothing is uploaded — you can drop many AAC files at once and each is converted separately with its own preview player and Download button. The only real limit is your device’s memory, so very large files of several hundred megabytes convert more comfortably on a desktop than on a phone.
Does it work on iPhone, Mac and Android?
Yes, it runs in any modern browser on Windows, Mac, Linux, iPhone and Android, with nothing to install and no account needed, so you can convert AAC to WAV on a laptop or straight from your phone. The first use downloads a one-time converter of about 32 MB, which your browser then caches so later conversions start instantly.
