WMA to MP3

Choose or drag your WMA files onto the box above, pick a bitrate, and each file is converted to MP3 automatically — then click Download. The conversion runs inside your browser, so nothing is uploaded and you can convert as many files as you want, free.

Yes. It is completely free with no signup, and your files never leave your device because the conversion runs locally in your browser rather than on a server. That makes it safe for private recordings, voice memos and unreleased music, and it means there is no upload wait.

There is no size limit imposed by us, because your files are never uploaded — the only real limit is your device’s memory. Very large files (roughly over a few hundred MB) may be slow or run out of memory on phones, so a desktop browser is best for long recordings.

Some quality loss is unavoidable because both WMA and MP3 are lossy formats, so re-encoding discards a little more data. Choosing a higher bitrate such as 256 or 320 kbps keeps the difference inaudible for almost everyone; 192 kbps is a good balance of quality and file size.

WMA is a Microsoft format that most iPhones, Android music apps and car head units do not support, so the file appears unplayable or is skipped entirely. MP3 is supported almost everywhere, which is why converting solves the problem permanently.

Pick 192 kbps for everyday music and podcasts — it sounds good and keeps files small. Use 256 or 320 kbps when you want the best quality for music you care about, and 96 or 128 kbps for spoken-word audio like voice memos where small file size matters more than fidelity.

Yes. It runs in any modern browser on Windows, Mac, Linux, iPhone and Android, with no app to install. The converter is downloaded once the first time you convert something, then cached, so later conversions on the same device start instantly.
