XWMA to OGG Converter
FileFlip converts XWMA to OGG entirely inside your browser, using WebCodecs and 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 OGG?#
- 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 OGG and the conversion starts on its own. FileFlip usually downloads nothing, falling back to 30.8 MB of WebAssembly if your browser cannot encode these codecs itself, then runs WebCodecs and FFmpeg on your own machine.
- Save the OGG file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting XWMA to OGG lose quality?#
Sometimes. When the codecs inside the XWMA file are ones the OGG container can hold, the streams are copied straight across and nothing at all is lost. When they are not, the file has to be decoded and encoded again, and that step does cost a little quality.
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 OGG actually does to the file#
Converting XWMA to OGG runs on WebCodecs and FFmpeg, usually downloads nothing, falling back to 30.8 MB of WebAssembly if your browser cannot encode these codecs itself, copies the streams through when the codecs fit and re-encodes when they do not.
| Engine | WebCodecs and FFmpeg |
|---|---|
| Conversion path | One step: XWMA → OGG |
| Downloaded to your browser | Nothing in most browsers, or 30.8 MB if yours cannot encode these codecs itself |
| Quality | Lossless when the codecs fit, lossy when they do not |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Encoded streams | Sometimes | Survives for some files and not others. |
Worth knowing before you start:
- whether the browser can do this without FFmpeg depends on the codecs it exposes through WebCodecs
- the encoded streams are copied when the file's codecs fit the target container, and re-encoded when they do not
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 OGG file?#
An OGG file is an Ogg-container file that, under the Xiph.Org Foundation's own naming convention, holds audio encoded with the Vorbis codec, an open, royalty-free lossy compressor comparable to MP3 or AAC.
Use OGG for Vorbis-encoded audio on Linux, in games, or anywhere royalty-free lossy compression matters more than universal playback.
Convert OGG to MP3 or AAC when the destination device or software has no Vorbis decoder, which is still common on Windows and iOS without a third-party player.
XWMA to OGG 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.
What's the difference between OGG and OGA?
OGG and OGA are the same Ogg container format with different extensions marking what's inside. Since 2007, Xiph.Org's convention reserves .ogg for audio specifically encoded with Vorbis, while .oga is the codec-agnostic extension for Ogg audio that might hold Vorbis, FLAC, Speex or another codec. In practice many tools ignore the distinction and use .ogg for any Ogg audio.
