What's the difference between WMA and WAV?
WMA (Windows Media Audio) and WAV (Waveform Audio File Format) solve different problems: WMA is a lossy compression format built for legacy Windows audio files, while WAV is a lossless compression format whose strength is studio recording, audio editing, broadcast. In practice you will meet WMA when dealing with legacy Windows audio files, and reach for WAV when you need studio recording, audio editing, broadcast — the table below compares them point by point.
| WMA | WAV | |
|---|---|---|
| Full name | Windows Media Audio | Waveform Audio File Format |
| Developed by | Microsoft | Microsoft & IBM |
| Released | 1999 | 1991 |
| Compression | Lossy compression | Lossless compression |
| Typical use | legacy Windows audio files | studio recording, audio editing, broadcast |
| File extension | .wma | .wav |
| MIME type | audio/x-ms-wma | audio/wav |
Why convert WMA to WAV?
WMA (Windows Media Audio) is a lossy audio format Microsoft released in 1999 for Windows Media Player. Once common on Windows PCs and portable players, it has faded from modern devices — phones, Macs, and car systems often cannot play WMA, which is why most people convert it to MP3. Here is when WAV is the better choice:
- →WAV is uncompressed — the safest format for editing, mixing, and mastering.
- →Audio software, samplers, and DAWs accept WAV without any decoding quirks.
- →It runs in the cloud — 10 free conversions a day with files up to 200 MB (20/day and 500 MB with a free account) — so even a phone or an old laptop converts at full speed.
Before you convert: three quick tips
- ●Decide the use first: 320 kbps for critical listening, 128 kbps when size matters most, and the 192 kbps default for everything else.
- ●Core audio metadata (title, artist) carries over to WAV where the format supports it; extras like embedded cover art vary by format.
- ●Keep your original WMA — conversion never modifies it, and if you later need a different target format, starting from the original always gives the best quality.
WAV conversion settings explained
Bitrate controls the quality-versus-size tradeoff of your WAV file. Filevo defaults to 192 kbps — the sweet spot for music: about 1.4 MB per minute of audio, indistinguishable from the source for the vast majority of listeners.
How to choose: 128 kbps suits voice, podcasts, and audiobooks (≈0.96 MB per minute — fully transparent for speech); 192 kbps is the everyday music setting (≈1.4 MB per minute); 320 kbps is for archiving and critical listening (≈2.4 MB per minute, the ceiling of what the format can deliver).
Rule of thumb: when unsure, keep the default. Pick 320 kbps for a music collection you plan to keep, or 128 kbps to halve the size of a voice note before sending it.
How the conversion works
Filevo's WMA to WAV conversion is powered by FFmpeg, the open-source media framework behind much of the world's video infrastructure. We run it with compatibility-first settings tuned for everyday playback, and stream progress back to your browser in real time. Because everything runs in the cloud, your device's CPU stays idle — the browser only uploads and downloads.

What is WAV?
WAV (Waveform Audio File Format) is an uncompressed audio format created by Microsoft and IBM in 1991. It stores raw PCM samples — the exact waveform with zero quality loss — which makes it the standard for studio recording, audio editing, and broadcast, at the cost of large files.

WMA to WAV converter FAQ
How do I convert WMA to WAV for free?
Drop your WMA file into the converter at the top of this page, confirm WAV as the target, click Convert, and download the result. It is genuinely free: 10 free conversions a day with files up to 200 MB (20/day and 500 MB with a free account), no watermarks, no software to install, no account required.
Is it safe to convert WMA files online?
Yes. Transfers are TLS-encrypted end to end, and conversion is fully automated — no human ever sees your files. Your uploaded WMA is deleted the moment conversion finishes, and the converted WAV auto-deletes after 24 hours (you can delete it sooner). We never use your files for AI training or share them with anyone.
Will I lose quality converting WMA to WAV?
WAV is lossless and preserves the decoded data exactly. One honest caveat: detail that WMA already discarded cannot be recovered — converting stops any further quality loss, but it cannot restore what is gone. Expect the file to get larger.
How long does WMA to WAV conversion take?
Usually seconds. The conversion itself takes from under a second to a few seconds for images and audio — most of the wait is the upload, which depends on your connection speed. Since processing happens in the cloud, your device stays fast, and you can run several conversions in parallel.
Can I convert WMA to WAV on iPhone or Android?
Yes. Filevo runs entirely in the browser, so it works the same on iPhone, Android, tablets, and computers — no app to install. On mobile, tap Browse Files to pick from your photos or files.
What's the maximum file size?
Anonymous conversions accept files up to 200 MB; a free account raises that to 500 MB. Paid plans go from 1 GB up to 10 GB per file, with higher daily limits and priority queues.
Can I convert multiple files at once?
One file per conversion today — though you can start several conversions in parallel. Batch upload with zip download is on the near-term roadmap.
What will the converted file be named?
Your original name is kept and only the extension changes — holiday.wma becomes holiday.wav, so files stay easy to find.
Whether you need studio recording, audio editing, broadcast or simply a file that works where WMA will not open, the converter above turns WMA into WAV in seconds — free, private, and with nothing to install. Bookmark this page for the next time a WMA file refuses to cooperate.
