AIFF to WAV Converter

How to Convert AIF to WAV Online

1. Upload Your AIF Files: Drag and drop or click "Add Files" to select .aif or .aiff files. GarageBand exports, Logic Pro bounces, Pro Tools renders, and macOS CD-rips all work — both extensions point at the same Audio Interchange File Format. Batch is supported, so you can drop in an entire session folder at once.
2. Pick the WAV PCM Encoding: Default is 16-bit little-endian PCM, the native WAV encoding that Windows DAWs, samplers, and broadcast tools expect. Choose 24-bit little-endian for studio masters with extra headroom, 32-bit little-endian for DAW intermediates, 16-bit big-endian when a downstream tool wants Mac byte order, or A-law / μ-law for telephony archives.
3. Set Sample Rate, Channels, and Trim (Optional): Match the source rate (typically 44.1 kHz for music, 48 kHz for video audio) or pick from the sample-rate dropdown (8 kHz to 48 kHz). Choose mono or stereo. Optionally trim using start time + duration in seconds (12.5) or HH:MM:SS.sss format (00:01:30.500).
4. Convert and Download: Click Convert. Files convert in your browser session and download individually or as a ZIP — no sign-up, no watermark.

Why Convert AIF to WAV?

AIF and AIFF refer to the same Audio Interchange File Format — Apple's uncompressed PCM container from 1988. The .aif extension is the original 3-character form (a holdover from classic Mac OS file-type conventions); .aiff is the longer modern spelling. The bytes inside are identical, and most tools accept either extension. WAV is Microsoft's RIFF-based PCM container from 1991. Both store bit-perfect PCM audio; the difference is which platform treats the file as native. Common reasons to convert AIF → WAV:

• Windows DAW and sampler compatibility — Older Windows-side hardware samplers, broadcast playout systems, and certain VST sample players load WAV faster and more reliably than AIF. Many such tools either reject .aif outright or stumble on the big-endian byte order.
• Mixed Mac/Windows collaboration — Sending stems from Logic Pro on macOS to a mixer running Reaper, Cubase, or Pro Tools on Windows? WAV is the universal lingua franca and avoids byte-order surprises.
• Broadcast and BWF workflows — Broadcast Wave Format (BWF) is a WAV extension used by radio, TV, and post-production for time-stamped audio with originator metadata. Converting AIF to WAV is the first step before adding BWF chunks.
• CD authoring on Windows — Windows-side audio CD authoring tools (Nero, ImgBurn audio mode) historically expect WAV for Red Book CD masters.
• Software that simply doesn't recognize .aif — Some upload forms, web players, and older consumer apps accept .wav but flag .aif as "unknown." A lossless WAV copy sidesteps the issue without re-encoding.
• Standardizing a mixed library — If your sample library or stems folder is half AIF (from Logic) and half WAV (from Reaper/Cubase), converting everything to WAV gives a consistent set that any tool can open.

Frequently Asked Questions

Is .aif different from .aiff?

No — they're the same Audio Interchange File Format. .aif is the older 3-character extension from classic Mac OS file-type conventions; .aiff is the longer modern spelling. The file contents are byte-for-byte identical, and XConvert accepts either as input. Some Windows tools auto-rename .aiff to .aif during transfer; that rename does not change the audio inside.

Will converting AIF to WAV lose any audio quality?

No. Both AIF and WAV store uncompressed PCM. When you keep the same bit depth, sample rate, and channel layout, the conversion is bit-perfect — the audio samples are identical, only the container header and PCM byte order change. Quality only changes if you deliberately pick a lower bit depth (e.g., 24-bit AIF down to 16-bit WAV) or a lower sample rate, in which case dithering / resampling applies.

Should I pick 16-bit or 24-bit WAV?

Match the source. If your AIF is 16-bit / 44.1 kHz CD-quality (typical for older Mac sessions and CD rips), output 16-bit WAV — going to 24-bit doesn't add information that wasn't there. If your AIF is a 24-bit Logic Pro studio recording, keep 24-bit WAV to preserve the extra dynamic range. Drop to 16-bit only when the destination requires it (audio CD authoring, certain hardware samplers).

What's the difference between AIFF and AIFF-C?

Standard AIFF (sometimes called "AIFF-PCM") stores raw uncompressed big-endian PCM. AIFF-C (Compressed) extends the same container to allow compression types like A-law, μ-law, ADPCM, and even MP3-style codecs. The "sowt" AIFF-C variant carries little-endian PCM specifically so Mac tools can write WAV-style PCM data without byte-swapping. XConvert reads all of these on input; the WAV output codec dropdown lets you choose how the PCM is laid out in the resulting WAV.

Why does my WAV have the same file size as my AIF?

Because the audio data is identical. AIF and WAV are both uncompressed PCM at the same bit depth, sample rate, and channel count, so the payload size is the same. Only the small header differs (a few hundred bytes). A 5-minute 16-bit / 44.1 kHz stereo file is roughly 50 MB in either format.

Can I batch convert a folder of AIF stems to WAV?

Yes — drop in the entire stems folder and the files convert in parallel within your browser session. Settings can apply uniformly across the whole batch (typical for stems where you want consistent encoding) or be tuned per file. Downloads come individually or as a single ZIP.

Will loop points and musical metadata transfer?

The audio data transfers bit-perfectly. AIF stores loop points and musical-key metadata in dedicated chunks (MARK, INST); WAV's equivalents (cue, smpl) exist but tooling support is inconsistent. Loop and instrument metadata may not survive the round-trip cleanly. If you rely on loop points (e.g., Apple Loops, sampler instruments), keep an AIF copy alongside the WAV deliverable.

Can I trim a long AIF recording and save just the part I need as WAV?

Yes. Use the trim section to enter a start time and duration. Both fields accept seconds (12.5) or HH:MM:SS.sss format (00:01:30.500). Useful for pulling a single song out of a long live-show AIF or extracting a clean take from a Logic Pro tracking session before delivering as WAV.

Does this preserve sample rate and bit depth automatically?

By default, yes — the converter reads the input AIF's sample rate, bit depth, and channel layout and produces a WAV that matches. You only need to touch the dropdowns when you deliberately want to change one of those values (e.g., downsample 96 kHz to 48 kHz for video work, or fold stereo to mono for a podcast).
