Free online AIF to WAVE converter

Source format: AIF

AIF usually refers to AIFF or AIFC, Apple’s audio interchange file formats. They are commonly used in professional audio production, especially on macOS, in digital audio workstations, sample libraries, and archival workflows. AIFF is typically uncompressed, which makes it a good choice for preserving audio quality during editing and mastering. AIF/AIFF files often contain high-quality PCM audio and may include metadata such as track names and markers.

Target format: WAV

WAV is Microsoft’s Waveform Audio File Format, one of the most widely supported audio containers on Windows, macOS, Linux, and in hardware and software players. Like AIFF, WAV commonly stores uncompressed PCM audio, so converting between the two usually preserves quality when no re-encoding is needed. WAV is widely used for editing, playback, broadcasting, game audio, and general interchange because of its broad compatibility.

How to perform the conversion

The simplest way is to use a desktop audio tool such as Audacity, FFmpeg, or SoX. If you want a quick browser-based option, you can convert the file on 101convert.com for free without installing any software.

Using Audacity

1. Open the AIF file in Audacity with File → Open.
2. Check that the audio plays correctly and that the project sample rate matches your source if needed.
3. Choose File → Export → Export as WAV.
4. Select the desired WAV encoding, usually WAV (Microsoft) signed 16-bit PCM for maximum compatibility.
5. Save the file with a .wav extension.

Using FFmpeg

FFmpeg is a reliable command-line option for direct conversion:

ffmpeg -i input.aif output.wav

If you want to force standard PCM WAV output, you can use:

ffmpeg -i input.aif -c:a pcm_s16le output.wav

Using SoX

SoX can also convert AIFF to WAV:

sox input.aif output.wav

Notes on quality, compatibility, or limitations

AIFF to WAV is usually a lossless container conversion when both files use PCM audio. In that case, the audio quality stays the same, and only the file container changes. However, if the source AIF uses compressed AIFF-C or a non-PCM codec, the conversion may involve decoding and possibly re-encoding, depending on the tool and settings.

Some AIFF files may contain metadata, markers, or loop points that do not transfer perfectly to WAV, since WAV metadata support is less consistent across applications. Also, AIFF is common on macOS, while WAV is often preferred for cross-platform compatibility, so the conversion is mainly about workflow and compatibility, not audio quality improvement.
