XWMA to AIFF Converter
FileFlip converts XWMA to AIFF entirely inside your browser, using FFmpeg compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert an XWMA file to AIFF?#
- Drop your XWMA file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to AIFF and the conversion starts on its own. FileFlip downloads 30.8 MB of WebAssembly the first time and nothing after that, then runs FFmpeg on your own machine.
- Save the AIFF file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting XWMA to AIFF lose quality?#
AIFF is a lossless format, so nothing further is lost here, but nothing is recovered either. Whatever the XWMA encoder already threw away is gone, and the AIFF file will usually be several times larger for exactly the same content.
Is it safe to convert XWMA files online?#
Yes, because nothing is uploaded. FileFlip converts XWMA files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What XWMA to AIFF actually does to the file#
Converting XWMA to AIFF runs on FFmpeg, downloads 30.8 MB of WebAssembly the first time and nothing after that, writes a lossless file that cannot recover what the source already discarded, and drops encoded streams.

What is an XWMA file?#
An XWMA file holds audio compressed with Microsoft's WMA codec inside a RIFF container variant built for XAudio2, the low-level audio API Microsoft supplies to Xbox and Windows game developers, so the format appears almost exclusively as a game asset rather than as a general music file.
XWMA belongs inside a game's own audio pipeline, built with XAudio2, where its job is efficient streaming playback rather than general storage.
Convert XWMA to WAV or MP3 when working with audio extracted from a game, such as for modding, preservation, or listening to a soundtrack outside the game itself.
What is an AIFF file?#
An AIFF file stores uncompressed PCM audio samples in Apple's Audio Interchange File Format, a structure the company built on Electronic Arts' IFF in 1988 for professional and Mac-native audio.
Use AIFF for recording and editing on macOS, where it's the native uncompressed format for tools like Logic Pro and GarageBand.
Convert AIFF to WAV for compatibility with non-Apple software, or to FLAC or MP3 once editing is done and the file needs to be smaller for distribution.
XWMA to AIFF questions people ask#
What creates an XWMA file?
XWMA files come from game development tools built on Microsoft's XAudio2 API, and from extracting audio assets out of Xbox 360 and Windows games that used XAudio2 for their sound. It is not a format any general recording or editing software produces on its own.
What plays XWMA files?
VGMStream, the game-audio playback tool, decodes XWMA directly, and its plugins let foobar2000 and Winamp play it too. Ordinary media players do not recognize the format, since it was built specifically for XAudio2, not for general playback.
What should I convert an XWMA file to?
Convert XWMA to WAV to preserve full quality for editing, or to MP3 for a smaller file to listen to outside the game it came from. Either target opens in ordinary media players and editors, unlike the original XWMA file.
Is AIFF a lossless format?
Yes, AIFF is lossless: it stores raw, uncompressed PCM audio samples with nothing removed or approximated, so what you hear back is identical to what was recorded. Unlike FLAC, standard AIFF doesn't compress the audio at all, so there's no encode-decode step where anything could go wrong.
