Convert WMA to AIFF when you are in a Mac pro-audio workflow or feeding a sampler. WMA is Windows Media Audio — Microsoft’s lossy format from the Windows Media Player era, lingering in old libraries and devices; AIFF is Apple’s uncompressed audio format — the Mac-world twin of WAV, still standard in pro audio and sampling. Upload your WMA, hit convert, download the AIFF — free, no sign-up, no watermark.
On ConvertFormat the matrix is the interface: the WMA to AIFF Converter is organised by the format you have and the format you need, because "change the format" is the whole job description — pick the pair, convert once, from the best original you have.

WMA is Windows Media Audio — Microsoft’s lossy format from the Windows Media Player era, lingering in old libraries and devices. AIFF is Apple’s uncompressed audio format — the Mac-world twin of WAV, still standard in pro audio and sampling. The audio is decoded once and re-encoded as AIFF; tags and artwork are not carried across, so re-add them in your player if they matter. File sizes stay in the same ballpark — both formats compress with loss, so the AIFF lands within roughly a third of the WMA's size at these quality settings. People make this exact swap when you are in a Mac pro-audio workflow or feeding a sampler.

Why people pick this over other converters
No account, ever. Most big converter sites push sign-ups and paid tiers for basic jobs. Here the tool just works.
No watermarks and no job counters on standard tools — fair-use rate limits keep things fast for everyone — and a generous 200 MB upload limit.
Private by design: your file is processed in a temporary folder and deleted the moment your download finishes. Nothing is stored or shared.
Fast: this page is a fraction of the size of the ad-heavy alternatives, and the same account-free toolbox has 386 other tools when you need them.
FAQ
Will converting WMA to AIFF lose quality?
The AIFF will be a bit-perfect copy of what is in your WMA — but WMA already threw detail away when it was created, and no conversion can invent it back. Expect a much bigger file with exactly the same quality, which is worth it only for editing or archiving.
When should I convert WMA to AIFF?
Convert when you are in a Mac pro-audio workflow or feeding a sampler. If your WMA already opens where you need it, converting buys nothing — this swap earns its keep the moment a device, app or upload form refuses WMA but accepts AIFF.
Is this really free?
Yes — completely. A short ad before processing keeps every tool free; no account, subscription or credits are ever required.
What happens to my file?
It is processed in a temporary folder and deleted the moment your download finishes. We never store, view or share uploads.
Do I need to install anything?
No. Everything runs in your browser session against our servers — any phone, tablet or computer works.
