Free online AIFF to WAVE converter

Source format: AIFF

AIFF (Audio Interchange File Format) is an uncompressed audio format developed by Apple. It is widely used in professional audio production, especially on macOS systems, because it preserves high audio quality and supports standard PCM audio data. AIFF files are common for music editing, mastering, archiving, and sample libraries. Because the audio is usually uncompressed, AIFF files are often larger than compressed formats such as MP3.

Target format: WAV

WAV (Waveform Audio File Format) is a widely supported audio container used across Windows, macOS, Linux, and many hardware devices. Like AIFF, WAV commonly stores uncompressed PCM audio, which makes it a good choice for editing and archiving when you want to preserve original quality. Its main advantages are broad compatibility, simple structure, and excellent support in audio software, DAWs, and media players.

How to perform the conversion

The simplest way to convert AIFF to WAV is to use the built-in converter on 101convert.com, which lets you convert the file online for free without installing any software.

1. Open the 101convert.com AIFF to WAV conversion page.
2. Upload your .aiff or .aif file.
3. Select WAV as the output format if it is not already selected.
4. Start the conversion and wait for the process to finish.
5. Download the resulting .wav file.

If you prefer desktop software, Audacity is a common choice for this conversion:

1. Open the AIFF file in Audacity.
2. Choose File → Export → Export as WAV.
3. Select the desired WAV encoding, such as WAV (Microsoft) signed 16-bit PCM for maximum compatibility.
4. Save the exported file.

Another option is FFmpeg, which is useful for batch conversion:

ffmpeg -i input.aiff output.wav

Notes on quality, compatibility, and limitations

AIFF to WAV is usually a lossless conversion when both files use PCM audio, because the audio samples can be copied without re-encoding. In that case, quality remains unchanged. However, if the source AIFF uses a compressed or unusual codec, the conversion may require decoding and re-encoding, which can affect compatibility or metadata handling.

Some differences to keep in mind:

• Metadata support may not transfer perfectly between formats or software.
• Loop points and other AIFF-specific data may be lost in some converters.
• Sample rate, bit depth, and channel count should be preserved if you want an exact copy of the audio content.
• For maximum playback compatibility, choose standard PCM WAV output.

If you need a simple, no-install option, the online converter on 101convert.com is convenient; for editing or batch jobs, desktop tools like Audacity or FFmpeg are often better.
