Bitrate converts audio files from one format to another. Everything it needs, FFmpeg included, is inside the app.
Before you start
You’ll need a Mac with Apple silicon running macOS 14 or later. Bitrate doesn’t run on Intel Macs.
Convert your first files
Move Bitrate to Applications
Drag Bitrate into your Applications folder and open it. It’s signed and notarized, so it opens without a warning.
Pick a preset
Choose a format and preset from the format menu, for example AAC 256 kbps. Bitrate remembers it next time. See Choose a format and preset if you’re not sure.
Drop your files
Drag files onto the Bitrate window or its Dock icon, or choose Open With›Bitrate in the Finder. Every file joins the queue and starts converting, with its own progress bar.
Find the results
By default each new file is saved next to its original. Click Show in Finder on a finished file to see it.
Choose where files go
In Bitrate’s settings, change the output from Next to source file to a folder of your choice. Bitrate never writes over an existing file: if the name is taken, it adds -1, -2 and so on.
Convert several at once
Files convert one at a time by default, which is kindest to your disk. Turn on parallel mode in Bitrate’s settings to run up to half your CPU cores at once. You can switch it on while a queue is running.
If a file fails
Click the failed file to see FFmpeg’s error details. Retry Failed tries again, and Clear Finished tidies the list. If it keeps failing, open a support ticket with the error and the file’s format.
