How it works
- Choose the MP3 file (up to 500 MB and 3 hours).
- Pick a bitrate and, if you need it, a sample rate. The defaults suit speech and music alike.
- Download the M4A. It is deleted from the server after 60 minutes.
Questions
Is quality lost?
Yes, a little: MP3 and M4A are both lossy, so this is a second encode. 192 kbps or higher keeps it hard to hear.
What happens to my file?
It is uploaded to our server, processed there, and both the upload and the result are deleted automatically 60 minutes after the job started. Nothing is kept, nothing is used for anything else, and nobody looks at it.
What are the limits?
Files up to 500 MB and 3 hours long. One job runs at a time on the server, so at busy moments yours may wait a little.
Do I need an account?
No. There is nothing to sign up for and nothing to install.
