Encoding speed depends on the processor available to this tab during this AIFF-to-MP3 job.
Available memory can limit very large AIFF conversion jobs.
Keep the source until the MP3 result passes a full playback check.

MP3 serves phones, websites, podcasts, and universal playback, whereas AIFF commonly serves DAWs, mastering tools, and Apple workflows.
For AIFF-to-MP3 delivery, plan for quality loss from further lossy encoding.
After leaving AIFF, the receiving app must support the streams encoded inside MP3, not only its extension.

AIFF to MP3 taking too long? Check available memory; long, high-resolution sources need substantially more.
MP3 converted from AIFF not opening? Test a compatible player and inspect the output streams.
A MP3 extension alone may not be enough; verify the required internal codec.

When does AIFF to MP3 conversion make sense?

It is useful when AIFF media created for lossless production must enter a MP3 system designed for easy sharing.

Where is the AIFF source processed?

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

How can I approve MP3 converted from AIFF?

Test the MP3 file in the receiving app and compare duration, channels and loudness with the AIFF source.
