What to expect from AAC to MP3
What changes in the file, and what to check before you share the result.
Compressed a second time

Why MP3
MP3 plays on virtually every phone, computer, car stereo, and app.
AAC to MP3 questions
Short answers about limits, privacy, and keeping the converted file.
Is the AAC to MP3 converter free?
Yes. Without an account you can convert up to 10 files a day, 2 at a time, up to 25 MB each. A free account adds monthly conversion credits and larger files.
How long are my files kept?
Guest uploads and results are deleted automatically after 1 hour. Conversions stay temporary when you are signed in too, unless you save a result to your workspace.
Can I get a permanent link to the MP3 file?
Yes. Save the result to a SteadyLink workspace and it gets a stable link. If you make a new version later, replace the file and the link stays the same.
