About the AAC format
AAC (.aac, MIME type audio/aac) is one of 11 audio formats Convert Me Pls supports. AAC is the successor to MP3: better quality at the same bitrate, and the default for Apple, YouTube and most streaming.
Working with AAC files
Whether you need to open a AAC file in software that doesn't support it, shrink it for the web, or hand it to a service that demands a specific format, the converters below cover every supported route — to and from AAC — for free, online, with no sign-up and no watermarks.
How Convert Me Pls handles AAC
Audio conversions use ffmpeg with high-quality encoders, choosing sensible bitrates so the output sounds clean wherever you play it.
