CAF to WMA Converter

Convert CAF to WMA Online

A .caf file is Apple's Core Audio Format — fine inside Logic Pro, GarageBand, and iOS recordings, but rarely playable on older Windows machines. WMA (Windows Media Audio) is Microsoft's legacy answer to MP3, so this conversion is the Apple-to-Windows crossing: pick it when a specific tool, old player, or workflow demands a .wma file. For anything modern, MP3 or AAC is the better target — see the FAQ below. If the CAF holds uncompressed PCM or Apple Lossless, the WMA result is a clean first-generation encode; if it already holds AAC or other compressed audio, you are re-encoding lossy to lossy and the discarded detail won't come back.

How to Convert CAF to WMA

1. Upload Your CAF File: Drag and drop your .caf onto the page or click "+ Add Files". You can queue several recordings and convert them all with the same settings in one pass.
2. Set the Quality Preset or Bitrate: Open the options and choose a Quality Preset ("Very High (Recommended)" through "Lowest"), or switch to Constant Bitrate, Custom Bitrate, or Variable Bitrate — 128 kbps suits speech, 192 kbps and up suits music. The output codec defaults to WMA v2 (WMAV2); WMA v1 is available under Audio Codec for older players.
3. Adjust Sample Rate, Channels, or Trim (Optional): Leave Audio Sample Rate and Audio Channel on "Original", or set them; the WMA Standard codec tops out at 48 kHz stereo, so a 96 kHz CAF master is downsampled to fit. Use Trim to export only part of a long recording.
4. Convert and Download: Click "Convert" and download your WMA file. No sign-up, no watermark.

CAF vs WMA at a Glance

Frequently Asked Questions

Should I convert CAF to WMA, or to MP3 or AAC instead?

Choose WMA only when something specific requires it — an older Windows Media Player setup, a legacy car stereo, or software that accepts .wma and little else. WMA was Microsoft's 1999 competitor to MP3 and is now a legacy format with far narrower support than MP3 or AAC. For a file that plays on essentially any phone, browser, and player today, use CAF to MP3; for a smaller file at similar quality, especially on Apple devices, use CAF to AAC. Reach for WMA when the destination, not the quality, is what's forcing your hand.

Will converting CAF to WMA lose quality?

It depends on what the CAF holds. If it stores uncompressed PCM or Apple Lossless (ALAC) — common for Logic Pro and GarageBand bounces — the encode to WMA is a first-generation lossy pass, and at 192 kbps and above the difference is hard to hear. If the CAF already wraps compressed audio such as AAC, you are re-encoding lossy to lossy: match or exceed the source bitrate to limit further loss, but detail the original codec already discarded can't be recovered. For an exact, editable copy instead, convert to CAF to WAV, which keeps the audio as uncompressed PCM.

My CAF is 96 kHz — what happens to the sample rate in WMA?

The standard WMA codec encodes audio up to 48 kHz with up to two channels (stereo), so a higher-resolution CAF master is downsampled to fit. That's fine for playback — 48 kHz comfortably covers the audible range — but it isn't an archival-grade transfer. If you need to preserve the original sample rate and bit depth for editing or mastering, convert to WAV instead and keep the WMA only for distribution to legacy players.

Why won't my CAF file open on Windows in the first place?

Core Audio Format is Apple's container, fully supported on macOS and iOS but rarely recognized by native Windows tools, which is exactly why people convert it. WMA gives you a file the old Windows Media Player stack reads natively. If broad compatibility matters more than matching a specific Windows tool, MP3 is the safer target — it plays virtually everywhere, including the same Windows machines, modern browsers, and mobile devices.

Can I trim a long CAF recording before converting to WMA?

Yes. CAF uses 64-bit file offsets and has no practical duration limit, so these files can run for hours. Use the Trim option to set a start time and duration and export just the region you need, which keeps the WMA small and skips encoding audio you'll discard anyway. For more involved edits, the dedicated audio cutter gives you finer control before you convert.

Is the conversion private, and how long are my files kept?

Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. In our testing, a 3-minute stereo CAF holding uncompressed 16-bit/44.1 kHz PCM (about 30 MB) converted to a 192 kbps WMA of roughly 4.3 MB.
