What is WMA?

Windows Media Audio. Microsoft's format. Common on older Windows systems and devices.

What is WAV?

Uncompressed audio format. Perfect quality with no data loss. Standard for music production and professional audio work.

Why Convert WMA to WAV?

WMA to WAV is the editing-and-archival route out of Microsoft's legacy format. WMA files mostly date from the 2000s — Windows Media Player rips, old dictaphones and voice recorders, radio archives — and today they are doubly awkward: modern software support is shrinking, and the format is lossy, so every additional conversion risks stacking damage. Decoding to WAV addresses both problems in one move. The WMA is decoded exactly once into uncompressed 16-bit PCM; from that point the audio is in the one format every DAW, editor, transcription service, and CD-burning tool on every platform accepts, and nothing that happens afterwards — cutting, cleaning, normalizing, exporting — costs any further quality. That makes WAV the right target when the recording needs work (restoring an old interview, editing a radio archive, preparing a memorial recording) or when you want a future-proof archival copy that will still open in thirty years regardless of what happens to Windows Media support. Be clear about the ceiling: WAV cannot restore what WMA compression discarded — the file becomes bigger, not better. For WMA Lossless sources, convert to FLAC instead (our WMA to FLAC tool) and keep bit-perfect quality at half the WAV size. DRM-protected WMA from defunct music stores cannot be converted by any third-party tool. Everything runs locally in your browser.

Who Uses This Converter

Restore old recordings

Dictaphone and interview WMAs decode once to WAV, ready for cleanup and editing without further loss.

Future-proof archiving

WAV will open in everything, forever — unlike WMA, whose support shrinks with each OS release.

Radio & broadcast archives

Legacy WMA archives become editable, universally compatible masters.

Transcription prep

Speech-to-text tools take WAV most reliably; decode the WMA once and feed them clean PCM.

Frequently Asked Questions

Why should I convert WMA files?

WMA is a legacy format that's poorly supported outside Windows. Most Macs, iPhones, Android devices, and audio editors handle WAV natively. Converting ensures your audio works everywhere.

Will the WAV file be larger than the WMA?

Yes, significantly. WAV is uncompressed, so files are typically 5-10x larger than the compressed WMA source. The trade-off is universal compatibility.

Can I edit the WAV file after conversion?

Absolutely. WAV is the most widely supported audio format for editing. Every DAW, audio editor, and production tool works with WAV files natively.

Does WMA to WAV restore quality?

No — standard WMA is lossy and the discarded detail is gone. The WAV holds the same audio uncompressed, which is what you want for editing and archiving: no further loss from here on.

What about WMA Lossless files?

WMA Lossless decodes bit-perfectly — to keep it that way efficiently, convert to FLAC with our WMA to FLAC tool (half the size of WAV, still lossless). Use WAV when an editor specifically needs uncompressed input.

Why not convert WMA straight to MP3?

MP3 is fine for listening (see our WMA to MP3 tool), but it adds a second lossy generation. If you plan to edit or archive the recording, decode once to WAV and do the lossy export only at the very end.

Is this WMA to WAV converter free?

Yes. Free users get 5 conversions per month. The output is limited to the first 10 seconds as a preview, with a 20MB input file size limit. Upgrade to Pro for unlimited, full-length conversions.
