AAC is not the same as M4A
AAC is a codec; M4A is one of the containers that can hold it. Converting AAC to MP3 re-encodes audio with loss, so keep the source file and avoid repeated conversions.
File processing
The file is uploaded and processed on the server. Processing deletes the original when it finishes; the MP3 is deleted after a complete download or through temporary-file cleanup. Technical conversion data is logged.
Frequently asked questions
Does renaming .m4a to .mp3 work?
No. Renaming a file does not change its encoding. Use the form to create an MP3 copy.
Will the MP3 sound better than the AAC?
It cannot recover detail from the original. Conversion produces another format; the result depends on the source and selected bitrate.
