WMA to MP3 converter
Turn Windows Media Audio (.wma) files into universally playable MP3s. Everything runs in your browser, so your files never leave your device.

WMA (Windows Media Audio) is Microsoft's audio codec, and for years it was the default output when you ripped a CD in Windows Media Player or recorded on an older Windows phone or dictaphone. It plays fine on Windows but stumbles almost everywhere else: iPhones, most Android devices, macOS, car stereos over USB, and browser-based apps frequently refuse to open a .wma file. That compatibility gap is why "convert WMA to MP3" is still one of the most common audio conversions people search for.
MP3 is the closest thing digital audio has to a universal format — nearly every phone, media player, DAW, upload form, and website accepts it without a codec pack. Converting a WMA to MP3 turns an awkward, Windows-only file into something you can drop into almost anything. Because this tool decodes and re-encodes entirely in your browser, there's no software to install and your recordings are never uploaded to a server.
How it works
- 1
Add your WMA file.
- 2
Convert it to MP3 in your browser.
- 3
Download the MP3.
When to use it
- Move a music library you ripped years ago in Windows Media Player onto an iPhone or into Apple Music, neither of which will sync .wma files.
- Turn old WMA voice recordings from a Windows dictaphone or phone into MP3s you can attach to email or drop into Google Drive for others to play.
- Prep a reference or sample clip that's stuck in WMA so it uploads cleanly to browser-based tools like Suno that expect common formats such as MP3.

FAQ
Will converting WMA to MP3 improve the audio quality?
No. WMA and MP3 are both lossy formats, so converting can only preserve or slightly reduce quality, never restore detail. The MP3 will sound about the same as the original at a comparable bitrate.
Why might my WMA file fail to convert?
DRM-protected WMA files (older purchased downloads) can't be decoded and won't convert. Some WMA variants may also be unsupported by the in-browser decoder, in which case the conversion will stop with an error.
Can I convert WMA to MP3 on a Mac or iPhone?
Yes. The conversion runs inside your browser (Safari, Chrome, or any modern browser), so it works the same on macOS, iOS, Windows, Android, or Linux with nothing to install. This is handy because Apple devices don't natively play or convert WMA at all.
What bitrate should I choose when converting WMA to MP3?
Match it roughly to the source. For music, 192–320 kbps keeps the MP3 sounding close to the original WMA; encoding well above the source bitrate just makes a larger file without adding detail. For spoken-word recordings, 96–128 kbps is usually plenty and keeps the file small.
Why can't I just rename a .wma file to .mp3?
Renaming only changes the extension, not the actual audio data inside — the file is still WMA-encoded, so most players will either error out or refuse to open it. A real conversion decodes the WMA audio and re-encodes it in the MP3 format, which is what this tool does.
