XWMA Converter
FileFlip converts XWMA files into 12 other formats entirely inside your browser, using FFmpeg and WebCodecs compiled to WebAssembly. The XWMA file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert an XWMA file?#
- Drop your XWMA file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
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 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.
The XWMA file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
XWMA 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.
