AIFC to WMA Converter

Convert AIFC to WMA Online

AIFC (Apple's AIFF-C container, introduced July 1991) holds Mac-side audio — usually uncompressed PCM, sometimes a legacy Mac codec — that Windows tools rarely recognize. This converter re-encodes it to WMA (Windows Media Audio), Microsoft's lossy format built on the ASF container. Convert to .wma when a legacy Windows program, an old in-car head unit, or a Windows Media Player library specifically expects that extension; for anything modern, AIFC to MP3 or AIFC to AAC is the more compatible pick.

How to Convert AIFC to WMA

1. Upload Your AIFC File: Drag and drop your .aifc file onto the page or click "Add Files." Queue several at once and they all run with the same settings.
2. Pick a Quality Preset: Leave it on the recommended preset, or open Quality Preset (Highest down to Lowest) to trade size against fidelity. The standard WMA codec tops out near 192 kbps, so the upper presets are already CD-grade.
3. Set the Bitrate (Optional): Switch to Constant Bitrate for a predictable file size, or Custom Bitrate to type an exact rate. If your AIFC is uncompressed PCM, 128-192 kbps keeps it transparent; for voice sources, 64-96 kbps is plenty.
4. Convert and Download: Click Convert and save your .wma file individually or as a ZIP. No sign-up, no watermark.

AIFC vs WMA — Format Comparison

Frequently Asked Questions

Will I lose quality converting AIFC to WMA?

It depends on what's inside the AIFC. If the source is uncompressed PCM — what most modern Mac apps write, including CD imports and "AIFF" exports from GarageBand and Logic — then WMA is a clean first-generation lossy encode, and at 128-192 kbps it sounds transparent to most listeners. If the AIFC was already compressed with a legacy codec (μ-law, A-law, or IMA ADPCM, common in older telephony and classic Mac OS files), WMA preserves that audio but can't restore detail the earlier compression already discarded. Either way, a higher bitrate avoids stacking new artifacts on the old ones.

Should I pick WMA v1 or WMA v2?

This converter defaults to WMA v2 (Windows Media Audio 9, released 2003), the more efficient standard encoder, and that's the right choice for almost everyone — it delivers CD-quality audio in the 64-192 kbps range and is decoded by any reasonably modern Windows Media stack. WMA v1 is the original 1999 codec; choose it only if you're feeding a very old device that predates v2 support. In our testing, a 3-minute uncompressed stereo AIFC (about 31 MB of PCM) re-encoded to 192 kbps WMA v2 produced a file of roughly 4.3 MB.

Why convert to WMA instead of MP3 or AAC?

Mostly compatibility with legacy Windows tooling. The standard WMA codec holds detail a little better than MP3 below about 64 kbps, but at 128 kbps and up the two are broadly comparable, and Microsoft's old "half the size of MP3" marketing was disputed by independent listening tests. WMA's real disadvantage is reach: Apple's Music app, most phones, and many web players don't handle it. Convert to WMA only when something specifically requires .wma — otherwise AIFC to MP3 or AIFC to AAC plays almost everywhere.

Will my WMA file play outside of Windows?

Native WMA support is mainly a Windows and Windows Media Player story. Some third-party players (VLC, foobar2000) and certain car stereos and DLNA devices decode it, but Apple devices, most smartphones, and a lot of modern browsers do not. If you need the audio to play broadly, keep a lossless copy with AIFC to AIFF or convert to a portable format instead, and reserve .wma for the one device or program that demands it.

Are my uploaded AIFC files kept private?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion. There is no sign-up, no watermark, and your files are never shared or made public. On a big batch the practical limit is upload time, not a per-file size cap.
