WMA to MP3

Convert WMA to MP3 in three steps

1. Choose one or more WMA files, or try the included sample.
2. Pick your MP3 bitrate and press Convert to MP3. Keep this tab open while it works.
3. Listen to the preview and save individual files or download the batch as a ZIP.

When WMA to MP3 is the right move

WMA is Windows Media Audio, the music format of early Windows players, and you will meet it in old music libraries, ripped CDs, and Windows voice recorders. MP3 plays in every car stereo, phone, podcast host, and upload form, so converting closes the gap between the file you have and the tool you need. Everything stays on your device while it runs, so private recordings never reach a server.

What happens to the audio inside

The converter opens the WMA file and reads WMA Standard, Pro, or Lossless audio. It decodes that audio and writes an MP3 at the bitrate you choose, which is small enough to email. Converting WMA audio to MP3 is a second lossy step for most sources, so match or exceed the source quality instead of going lower.

Size and settings

A 192 kbps MP3 uses about 1.4 MB per minute. Choose 128 kbps for speech, 192 kbps as the all-round default, and 256 or 320 kbps for music you plan to keep. The sample rate and channel layout of your WMA file are carried across, so a mono recording stays mono.

Troubleshooting and tips

WMA files protected by Windows Media DRM cannot be converted. Unprotected files, including WMA Pro and Lossless, decode normally but may take a little longer. The first conversion of this format downloads an extra decoder of about 30 MB, and your browser keeps it for later. Only the decoder is downloaded. Your file is never uploaded. Convert a short file first to confirm that your browser can decode it, then run the rest as a batch and download the ZIP. Keep the original WMA until you have listened to the MP3 from beginning to end.
