Convert WMA to WAV Online
WMA files have limited compatibility with professional audio software. Converting to WAV gives you universal compatibility for editing and production.
Since WMA is a lossy format, converting to WAV does not improve quality, but creates a file compatible with every audio application.
WMA is Microsoft's compressed audio format; WAV is uncompressed PCM. Converting WMA to WAV gives you a universally editable, lossless-container file that every DAW and audio tool accepts, which is exactly what editing and mastering workflows expect. This guide covers the one quality caveat, when the conversion makes sense, and how to do it in the browser.
What is WMA?
WMA (Windows Media Audio) is Microsoft's proprietary audio codec. While widely supported on Windows, it has poor compatibility elsewhere.
WMA files cannot be directly imported into many professional audio tools and have no support on iOS or many Linux applications.
What is WAV?
WAV is the universal audio format supported by every audio application, operating system, and professional audio tool ever made.
WAV's universal compatibility makes it the safest format for audio editing, broadcast delivery, and cross-platform workflows.
The Quality Caveat: WAV Cannot Add Back What WMA Removed
WMA (in its common lossy form) already discarded some audio data when it was created. Converting to WAV produces a larger, uncompressed file, but it does not restore the detail WMA threw away, it simply stops any further loss. Think of it as freezing the current quality in an editable container. That is exactly what you want before editing, because every subsequent operation runs on raw PCM samples with no additional compression damage. Just do not expect the WAV to sound better than the WMA; it sounds identical, only bigger and lossless from here on.
When to Convert WMA to WAV
- Editing in a DAW or audio editor: WAV is the universal working format; WMA support is patchy outside Windows.
- Cross-platform compatibility: WAV plays on macOS, Linux, and every editor, where WMA often does not.
- Archiving an editable master: WAV is a safe, open container for the working copy.
- Not for everyday listening: if you just want to play the file, keep the small WMA; WAV is roughly ten times larger for no audible gain.

Frequently Asked Questions
Is WMA to WAV conversion lossless?
No. WMA is a lossy format, so converting to WAV cannot recover the audio data already discarded by WMA compression.
Can I convert DRM WMA to WAV?
No, DRM-protected WMA files cannot be converted. Only DRM-free WMA files can be processed.
Why convert WMA to WAV?
For compatibility with professional audio software, DAWs, and cross-platform workflows.
How large will the WAV be?
WAV files are approximately 10x larger than equivalent WMA files.
What software can open WMA?
Windows Media Player, VLC, and Audacity can open WMA. Mac and iOS do not natively support WMA.
Does converting WMA to WAV improve sound quality?
No. WAV is lossless going forward, but it cannot recover detail the original lossy WMA already removed. The audio sounds the same; the benefit is an editable, universally compatible file with no further compression loss.
Why is the WAV file so much bigger?
WAV stores uncompressed PCM, roughly 10 MB per minute of CD-quality stereo, while WMA is compressed. The larger size is the cost of a lossless, edit-ready container.
