Convert WMA to MP3 Online

There's an irony to converting WMA: the people who need it most are usually on a Mac, and a Mac is exactly where WMA doesn't work. You've inherited a drive of old Windows rips, or migrated from a PC, and now a decade of music simply won't open. Installing yet another desktop converter to fix it — often bundled with adware — is an unappealing answer.

A browser tab is a better one. This page loads FFmpeg compiled to WebAssembly and does the conversion on your own machine, so it works identically on macOS, Windows, Linux, and phones, with nothing installed and nothing to keep updated. And unlike other online converters, your files are never uploaded — no server sees your music library, and there's no queue to wait in.

That matters at library scale. Server-based converters make you upload each file and download it back; here the conversion is local, so the only limit is your own machine. A typical track converts in a second or two.

The conversion itself is honest about what it can do: WMA and MP3 are both lossy, so this is a second encode. Use 192 kbps or above and the difference is inaudible for normal listening. If you happen to have WMA Lossless files, send those to FLAC instead — our WMA to FLAC tool keeps every bit.

What you get back is the one format nothing refuses. The rescued library will play in Apple Music, on your phone, in the car, on a smart speaker, and in every browser — which is the entire point of doing this at all.
