Drop your M4A here
Anywhere on this page works
Turn M4A files into AAC in this browser tab. Drop the file on the card above, check the output options under it, and download the AAC as soon as it is ready — there is nothing to install.
No account is needed, nothing is watermarked, and the upload is deleted once your download finishes.
Drop the file in, or pull it from Drive, Dropbox, OneDrive or a URL.
Output is already locked to AAC. Quality, size and metadata options sit under the card.
Download it straight away. Nothing is watermarked and no account is needed.
Every format we can turn into advanced audio coding, each on its own page.
M4A does not have to become AAC. Here is everything else it can be.
