Convert WMA to AC3 on Mac.
Local file processing, by renaming the file in Finder. No converter window and no upload queue.
Finder rename
report.wmareport.ac3
How the rename works
- 1
Start with report.wma
Put the WMA file in a folder RenameTo watches, such as Desktop or Downloads.
- 2
Rename it to report.ac3
In Finder, change .wma to .ac3, then press Return. The rename is the command.
- 3
Find the AC3 beside it
RenameTo produces the requested output and keeps a restorable backup of the original.
What happens under the hood
RenameTo reads the WMA with the appropriate local macOS media or document framework, then writes a new AC3 beside it. The file itself is not sent to a conversion server.
About the formats
WMA is the Windows Media audio format. AC3 is Dolby Digital audio.
Questions, answered
Does my file get uploaded anywhere?
No. File processing happens on your Mac. RenameTo does use the network for license validation, trial activation, and update checks, but your source files are not part of those requests.
What happens to the original WMA file?
RenameTo keeps a backup before processing. Undo restores the original alongside a format-changing output and does not delete that output. If the original name is already occupied, the restored copy gets “(restored)” in its name.
Can I convert a whole folder?
Yes. Rename multiple selected files in Finder and RenameTo queues each supported conversion, with a separate result and backup for every file.
Can I run the same conversion from a script?
Yes. The CLI command is: renameto ac3 *.wma
