Frequently asked questions
Is converting AAC to MP3 free?
Yes, completely free. No account, no daily limit, no watermark and no queue.
Does it work on a phone?
Yes. It works on iPhone, iPad and Android, with no app to install.
Is there a file size limit?
There is no size limit set by us. Files of hundreds of MB convert too; very large files take longer and are handled more comfortably on a computer than on a phone.
