How to open a .wma file
If double-clicking a WMA file did nothing useful, that is normal: the format is fine, your operating system just has no default application registered for it. This page explains the format and gives you a way to read one immediately.
What is a .wma file?
Windows Media Audio is an audio format developed by Microsoft, first appearing in 1999. It is normally produced by Windows Media Player rips.
Uses the ASF container. Rips made with 'copy protect music' enabled in old WMP versions remain locked to a licence store that no longer exists.

Open a .wma file in your browser
OpenAnyFile routes .wma to its HTML5 audio player, which plays a playback bar with duration and seeking.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .wma file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
- The extension is detected and the file is handed to the HTML5 audio player.
- Your WMA opens on its own viewer page: a playback bar with duration and seeking.
- Use fullscreen for a closer look, or download the file back out unchanged. No account, no upload, no watermark, no file-size gate.
What you can and cannot do with it here
Does not work
Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.
Is it safe to open a {E} file on a website?
It depends entirely on whether the website uploads it, and almost all of them do. That is a real problem when the audio file in question is a contract, a client deliverable or something under NDA. OpenAnyFile removes the question: the decoding happens inside your browser tab, so there is no transfer, no queue, no temporary storage and no retention window to read about in a privacy policy.
Frequently asked questions about WMA files
Can I open a .wma file without installing special software?
Yes. OpenAnyFile's HTML5 audio player runs in your browser, so you can read a WMA file with nothing installed. You get a playback bar with duration and seeking. For full editing you still need the original application — this is a viewer, not an editor.
How can I check a file really is a WMA file?
Look at the first bytes rather than the extension. A genuine WMA begins with 30 26 B2 75 8E 66 CF 11. Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .wma by mistake is easy to spot.
Is it safe to open a WMA file online?
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.
What is a .wma file, exactly?
Windows Media Audio — an audio/x-ms-wma format created by Microsoft since 1999. Uses the ASF container. Rips made with 'copy protect music' enabled in old WMP versions remain locked to a licence store that no longer exists.
Does the same viewer handle formats related to WMA?
Yes — the same engine also opens .mp3, .flac, .wav, so you can compare related files without switching tools.
