Is this AAC to WAV converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple AAC files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

What bitrate will the converted audio use?

We default to 192 kbps for MP3, 128 kbps for OGG/Opus, and 320 kbps for M4A/AAC. These settings are perceptually transparent — most listeners can't tell the difference in a blind test.

Will my metadata (ID3 tags, album art) be preserved?

Yes, when both formats support it. Tags carry over on conversions like MP3→M4A or FLAC→MP3. WAV has limited tag support, so some metadata may not transfer.

Will my AAC file open as WAV in Audacity?

Yes. WAV is natively supported by Audacity, Adobe Audition, Logic Pro, and all other major audio editors. Convert your AAC first, then import the WAV.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert AAC to WAV?

AAC files from iTunes purchases, iPhone voice memos, Apple Music downloads, and video exports from iMovie arrive in a compressed format that many professional audio tools do not handle natively. Avid Pro Tools, older versions of Ableton Live, and certain hardware samplers and drum machines require WAV input. When you want to process audio from an Apple device in a professional DAW session, converting AAC to WAV is often the first step before any editing or processing can begin.

WAV is the uncompressed, universally supported format that every professional audio application accepts without question. Hardware synthesizers and samplers from Elektron, Roland, and Native Instruments that accept audio import via SD card or USB all work with WAV. Broadcast playout systems, radio station audio libraries, and sound design software like SoundMiner index and play WAV files reliably. Providing audio stems as WAV to collaborators eliminates any possibility of format-related playback issues.

Converting AAC to WAV decompresses the lossy AAC audio into an uncompressed PCM representation. The WAV output will be an accurate, uncompressed version of whatever audio quality exists in the AAC file, but it will not restore information that was discarded when the AAC was originally created. This is not a quality upgrade, but it is a format upgrade that opens up compatibility. The WAV file will be substantially larger than the AAC source, typically ten to fifteen times larger, and will be immediately usable in any professional audio environment.

Quality & file size: AAC to WAV

Typical file sizes: AAC 2–5 MB → WAV 30–50 MB.

Both AAC and WAV use lossy compression. We transcode at high quality settings (equivalent to WAV's recommended web quality) to minimize generational loss.

Color depth: AAC supports standard color, WAV supports standard color.

Transparency: AAC does not support transparency. WAV does not support transparency — transparent areas become solid white.
