Is this AIFF 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 AIFF 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.

Is AIFF to WAV conversion lossless?

Yes — completely lossless. Both AIFF and WAV store uncompressed PCM audio data. Converting between them changes only the file container header, not the audio samples themselves. The resulting WAV is bit-for-bit identical in audio content to the source AIFF. No quality is lost, and no frequency content is removed.

What is the difference between AIFF and WAV?

AIFF (Apple) and WAV (Microsoft/IBM) both store raw uncompressed PCM audio — the same audio data, two different container formats. AIFF is native to macOS/iOS; WAV is native to Windows. Both are lossless. Both are large files. Both are standard in professional audio production. The choice between them is purely about platform compatibility: AIFF for Apple-centric workflows, WAV for Windows and cross-platform compatibility.

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.

AIFF vs WAV: format overview

AIFF

Audio Interchange File Format

Why convert AIFF to WAV?

AIFF and WAV are technically equivalent — both are uncompressed lossless audio formats storing raw PCM data. The practical difference is platform origin: AIFF was invented by Apple in 1988 and is natively supported on macOS and iOS. WAV was invented by Microsoft and IBM in 1991 and is the universal standard on Windows and in professional audio globally.

The conversion is necessary in cross-platform workflows. A Pro Tools session on Windows may not recognise AIFF files from a Logic Pro session on Mac without a specific codec. Broadcast facilities, podcast distribution platforms, and game engine asset pipelines often mandate WAV. Video editors (Adobe Premiere Pro on Windows, DaVinci Resolve) handle WAV more reliably than AIFF in cross-platform projects. Splice, Looperman, and sample marketplace platforms typically require WAV for sound pack submissions.

Because both AIFF and WAV store identical audio data (uncompressed PCM), converting between them is mathematically lossless — not a single sample changes. The output WAV is bit-for-bit identical to the AIFF source in terms of actual audio information. Only the file container changes.

File size is essentially unchanged — a 30 MB AIFF becomes a 30–32 MB WAV. The slight difference comes from the container metadata structure, not the audio data.

Common reasons to convert AIFF to WAV:

›Submit sound files to a Windows-based production house or broadcast facility that requires WAV
›Upload samples to Splice, Looperman, or other sample marketplaces that mandate WAV
›Use Mac-produced audio assets in Windows-based game development projects
›Ensure compatibility when collaborating on music production across Mac and Windows

Quality & file size: AIFF to WAV

Typical file sizes: AIFF 30–50 MB → WAV 30–50 MB.

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

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

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

Privacy: how FormatDrop handles your files

Your AIFF files are converted 100% inside your browser. They are never uploaded to our servers, never stored, and never seen by anyone other than you. This isn't a privacy policy claim — it's an architectural guarantee: our server has no endpoint that receives file bytes.
