WMA was developed by Microsoft and is poorly supported on Mac, iPhone, and most non-Windows software. fwip converts to MP3 entirely in your browser. No server, no upload, no account.

fwip works differently. The processing engine runs entirely in your browser. Your WMA is read from your device, processed on your CPU, and the result is saved back to your device. No server is involved. We literally cannot see your file.

No server processing

Everything runs on your device using WebAssembly. Your file never touches a network.

Frequently asked.

How do I convert WMA to MP3?
Drop your WMA file into fwip. It converts to MP3 in your browser. Download the result.
Is my audio file uploaded?
No. Conversion runs entirely in your browser using WebAssembly. Your audio file never leaves your device.
Why won't WMA play on Mac or iPhone?
WMA is a proprietary Microsoft format. Apple devices and most non-Windows software do not support WMA natively. Converting to MP3 solves this.
Will quality be preserved?
Both WMA and MP3 are lossy formats. Transcoding at a similar or higher bitrate will not degrade quality significantly.
Can I convert offline?
Yes. The offline version ($15, one payment) works without internet — useful for old recordings or secure environments.
