Convert AAC to WAV on Mac.
Local file processing, by renaming the file in Finder. No converter window and no upload queue.
Finder rename
report.aacreport.wav
How the rename works
- 1
Start with report.aac
Put the AAC file in a folder RenameTo watches, such as Desktop or Downloads.
- 2
Rename it to report.wav
In Finder, change .aac to .wav, then press Return. The rename is the command.
- 3
Find the WAV beside it
RenameTo produces the requested output and keeps a restorable backup of the original.
What happens under the hood
RenameTo reads the AAC with the appropriate local macOS media or document framework, then writes a new WAV beside it. The file itself is not sent to a conversion server.
About the formats
AAC is raw AAC audio. WAV is uncompressed audio suited to editing and archiving.
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 AAC 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 wav *.aac
