Format Details
WAV
WAV (Waveform Audio File Format) is an uncompressed audio container format developed by Microsoft and IBM for storing raw audio data. It preserves audio at full, lossless quality with no encoding artifacts, making it the preferred format for audio production, editing, and professional archival. WAV files are larger than compressed formats like MP3, but are universally supported and suffer no quality degradation when re-encoded.
audioAIFF
AIFF (Audio Interchange File Format) is an uncompressed audio container developed by Apple, commonly used in professional music production and macOS workflows. Convert to MP3, WAV, FLAC, and other formats.
audioConverting WAV to AIFF: what actually changes
WAV to AIFF is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .WAV and .AIFF each hold
.WAV is a audio format built for listening to or editing a recording, storing sample rate, channels and bitrate. .AIFF is a audio format built for listening to or editing a recording, storing sample rate, channels and bitrate. Converting between them is a decision about which of those two jobs the result needs to do.
What changes in the conversion
Both files belong to the audio category, so this is a like-for-like repackage: the same kind of content, stored in a different container. What changes is how .AIFF encodes sample rate, channels and bitrate — not what the file is about.
Quality and file size
Both .WAV and .AIFF are lossless, so the content itself survives the trip intact. The main difference is how efficiently each format packages sample rate, channels and bitrate — which is what changes the file size.
When this conversion is the right one
Reach for .AIFF when the software, device or platform you are sending to expects it — the content is the same audio, only the packaging differs. The reverse direction works the same way, so you can always convert back from .AIFF to .WAV using the same tool.
Tips for a clean WAV to AIFF conversion
Start from the original file
Convert the .WAV you started with, not an earlier .AIFF output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Audio/wav becomes audio/aiff. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Length decides the time
Conversion runs in real terms on duration: a few seconds of media finishes almost at once, while a full-length .WAV takes noticeably longer. Upload once and let it finish rather than retrying.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge audio files, split or compress the source first.
