Processing demand varies with the codecs found in the source during this MP3-to-WMA job.
Long MP3 files consume more memory and take longer to decode.
Check picture, sound, and timing in WMA before removing the source.

WMA serves Windows Media libraries and older devices, whereas MP3 commonly serves phones, websites, podcasts, and universal playback.
For MP3-to-WMA delivery, plan for limited support outside Microsoft ecosystems.
After leaving MP3, the receiving app must support the streams encoded inside WMA, not only its extension.

MP3 to WMA taking too long? Close other demanding apps, then test a short sample before the full file.
WMA converted from MP3 not opening? Test a compatible player and inspect the output streams.
Inspect the generated streams when an app recognizes WMA but refuses playback.

When does MP3 to WMA conversion make sense?

It is useful when MP3 media created for easy sharing must enter a WMA system designed for Windows playback.

Where is the MP3 source processed?

The browser prepares WMA from MP3 on this device instead of sending the source to a remote conversion server.

How can I approve WMA converted from MP3?
