Frequently asked questions
Is converting WMA to FLAC really free?
Yes. WMA to FLAC conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
Are my WMA files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so the WMA file never leaves your device. That is also why it works without an internet connection once the page has loaded.
Is there a file size limit for WMA to FLAC conversion?
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
